11 Vitamins, Nutrients & Peptides That Boost Immune Function

While immunity is an important part of everyday life, it’s hasn’t always been front and center when people think about their overall health. However, that has changed in recent years. Since the onset of the COVID pandemic, many people have begun thinking more seriously about their immune health. After all, the immune system is the first line of defense against pathogens such as the one that causes COVID-19. 

With more people than ever now focused on this type of preventive health care – the type that aims to prevent bad infections as opposed to simply treating them – natural and dietary health avenues are being explored more frequently. Those natural avenues tend to center around nutrients from food and other supplementation that can help give the body a boost when it needs it most.

Why is immune function important in the winter?

The immune system is important all year round, but it’s especially vital during the cold months. This is often when cold and flu seasons are at their peak. To complicate things further, research shows that cold temperatures also suppresses the immune system and provides viruses with optimal living conditions. These two factors play a large role in why it’s vital to keep your immune system in tip-top shape throughout the winter months.

No one wants to fall ill, and making sure that the immune system is running at its best is the only way to ensure that even if you do come into contact with a flu, cold, or even COVID, your body is prepared to fight it off and bounce back.

Peptides that boost immune function

Peptides are naturally occurring strings of amino acids that the body produces on its own. Unlike the typical amino acids that act as building blocks of protein, peptides are shorter chains, meaning they have fewer amino acids. That doesn’t mean they’re less important for health, just that they have different tasks to perform. One such task is making sure that the immune system gets the boost it needs to run properly.

Peptides naturally occur in the body; however, to boost your levels, you can eat foods that are high in protein such as meat, fish, dairy, eggs, whole grains, and beans. Peptides can also be found isolated in supplement form.

Some of the best peptides for immune health include:

Thymosin Alpha 1

Thymosin Alpha 1 is perhaps one of the most well-known peptides. It aids immune function and has also been used in the treatment of certain diseases. The peptide helps immune function by enhancing the action of immune cells known as killer T-cells so they’re better prepared to fight off infection.It also positively affects the action of dendric cells, which help to mediate the immune response on a cellular level.


Thymalin regulates the thymus, a gland that is key to producing T-lymphocytes, or immune cells, that aid in the adaptive immune response.Without proper amounts of this peptide, those cells will not be produced in adequate numbers and the immune system will suffer.


Also known as insulin growth factor one, IGF 1 binds to a receptor known as IGF 1R to encourage cell production throughout the entire body. Cells that are created include T-cells, which aid in immunity.


GHRP 6 acts as ghrelin, which is the hunger hormone. Its job is to invoke the action of IGF 1 so that more immune cells are created, thus boosting immunity.

CJC 1295

CJC 1295 affects the growth hormone, causing it to be released. This leads to a reaction that causes the thymus to create T-cells.

Vitamins that boost immune function

Vitamins are needed for the body to function, and many of them play a vital role in the immune system. Some vitamins that are good for boosting immune health include:

Vitamin C

Vitamin C is the most well-known immune booster, and for good reason. Research shows that vitamin C helps immune function by supporting cellular responses in both the adaptive and the innate immune systems. It can also prevent the entry of pathogens through the skin by supporting skin barrier function. Vitamin C can also enhance the body’s ability to fight off disease by accumulating certain phagocytic cells.

This vitamin can be found in a variety of fruits and vegetables such as oranges, strawberries, and red bell peppers.

Vitamin B6

Vitamin B6 has the ability to boost the immune response because it helps to increase the production of antibodies in the system, and enhances the way cytokines and chemokines interact with one another (cytokines and chemokines are molecules within the body that aid in cell signaling).

Vitamin B6 can be found in seafood, fortified cereals, and chickpeas.

Vitamin E

Vitamin E is found in high concentrations in immune cells; it aids the cells in modulating immune function. It also helps to regulate T-cells, improve the integrity of immune cells so that they are safe from damage, and encourage proper cell division.

The best sources of vitamin E include plant-based oils, nuts, seeds, and dark, leafy greens.

Nutrients that boost immune function

Other nutrients that play a vital role in boosting immune function include:


Zinc is a chemical element that has been shown to aid in the development and function of certain immune cells such as natural killer cells and neutrophils.

Red meat and poultry contain high levels of zinc.


Selenium has been shown to help lower oxidative stress, which occurs when free radicals outnumber antioxidants and cause inflammation within the body. Inflammation can hinder the immune system, so having enough selenium can help to lower the risk of immune-suppressing inflammation.

Broccoli, spinach, and green peas are great sources of selenium.


Iron is an important part of immune health because of the crucial role it plays in the maturation of immune cells. One type of cell that benefits from adequate iron levels are lymphocytes, which help with specific responses against certain pathogens.

Iron can be included in your diet through foods such as red meat, beans, and dark, leafy greens, or through supplementation.

6 Activities That Boost Immune Function

The way your immune system functions will determine your overall level of health. After all, it is the first line of defense your body has against pathogens and chronic illness. When the immune system is in good working order, the body is able to fight off infections more easily, which is a vital component of staying healthy.

Everyone’s immune system could use a little boost from time to time, especially in this day and age. Things such as leading a sedentary lifestyle, eating the wrong foods, and not getting enough sleep can all negatively affect how the immune system does its job. But by addressing specific lifestyle factors and performing activities that boost immune function, you can give your system the jolt it needs to protect you and your health.

How can I naturally boost my immune system?

There are plenty of ways to naturally boost your immune system. Many are simple lifestyle changes that can be implemented seamlessly into your daily routine. Let’s take a look at some specific immune-boosting activities everyone should do get that extra level of protection.

1. Get some shut-eye

Sleep and immune function work together symbiotically. This means that the amount and the quality of sleep you’re getting will be crucial in how well your immune system responds if pathogens enter your system.

Sleep doesn’t just affect one facet of the immune system, but several, as research has shown. For example, sleep and the circadian system, or the body’s natural sleep-cycle regulator, work together to help regulate the immune system. Both sleep and the circadian system help the body to communicate with the immune system, and when that communication is disrupted, it can lead to weakened immune function.

During sleep, your body has lower levels of stress hormones that can lessen the function of molecules called integrins. These molecules are designed to help immune cells known as T-cells stick to viruses to rid them from the body. When those hormones are lowered, the integrins are more well-equipped to help T-cells get into contact with infected cells and thus get them out of the body.

2. Practice mindful meditation

Mindful meditation is a practice designed to enhance awareness in daily life. Research has shown that this practice, when performed regularly, can help to increase the function of the immune system. It does this by modulating certain immune functions, such as the proinflammatory processes, enzyme production, and cell-mediated defense.

These parameters are important because they play direct roles in the immune function. For example, the proinflammatory process can cause an abundance of inflammation, which is bad for the immune system; and enzymes are needed to help protect against cell aging, which can decrease how well the immune system works.

3. Get moving

Exercise is important for overall health, but when it comes to the immune system, it is especially crucial to get the body moving on a regular basis. Research has shown that regular exercise can help to modulate the immune system. It does this by encouraging the circulation of important immune cells known as lymphocytes. During and after exercise, the body also releases other immune cells known as cytokines, which are crucial in protecting the body.

4. Adopt a positive mindset

It’s not possible to think happy thoughts every hour of every day. Everyone experiences annoyances and struggles. But having a positive mindset towards negative situations can help to increase how the immune system functions in the long run.

Research has shown that focusing on the positives help people increase the strength of their immune systems. One specific study had participants look at both positive and negative images. They were later asked to think about the experiment and underwent blood tests to determine immune function. The participants who remembered more positive images had better immune functioning for up to two years following the experiment.

This just goes to show that thinking about the silver lining can have a great impact on how well your body fights off illness.

5. Learn to cook

Diet may not be everything when it comes to healthy living, but it does make up a huge portion of how well the body works. Eating a diet rich in antioxidants, vitamins, minerals, and other nutrients will help to keep the immune system running as it should.

Research has shown that when a person is deficient in any nutrient, it can affect the way the body produces antibodies for pathogens as well as other immune cells. For example, natural killer cells are required to help contain infections within the body so that other immune cells can prepare to clear them out. These natural killer cells rely on having enough B6 and B12 within the body to keep them ready and able to do their job.

Learning to cook and eat with intention can help you get all the nutrients you need because you will be more in control of what goes into your body, and thus more in control of the fuel you give your immune system.

6. Spend more time outside

Being out in the great outdoors is great for both physical and mental health, but it can also positively affect how well the immune system functions. This is because the immune system needs vitamin D, and being outside is the best way to get it.

The immune system is vital to overall health, and keeping it running at its best will help you stave off illnesses and decrease your risk of developing chronic disease later in life.

How Meditation Can Affect Your Immune System

Meditation is a health practice that has been utilized by many cultures for thousands of years. Almost every type of religion has its own meditation practices; however, it isn’t just for religious people. In recent years, it has been used as a form of independent self-care to benefit both the body and the mind.

By definition, meditation is a mental technique or techniques that can be performed with the goal of heightened awareness and improved focus. People meditate today for religious reasons, to help ease physical pain and mental issues, and to help combat stress in everyday life.

What are the different forms of meditation?

There are nine specific forms of meditation, all of which are performed in different ways and by different cultures. Each type has its own focus, though many seem to share a similar goal of achieving peace and calmness.


Mindfulness meditation is a Buddhist type of meditation and is the most widely practiced form in the western world.It is aimed at acknowledging thoughts and allowing them to pass without dwelling on them. It tends to push towards observation and pattern recognition when it comes to the way people think.


Eastern religions such as Hinduism and Daoism use spiritual meditation. It is done using essential oils to enhance the experience, with the goal of reflecting on silence and connecting deeper with the universe or God.


Focused meditation revolves around concentration using internal or external influences. Examples of focused meditation include counting objects, listening to a repeating sound, or watching a candle burn. It is meant to help control and sharpen the mind’s focus.


This type of meditation revolves around activities that require movement, such as yoga, walking in the woods, or gardening. It is meant to bring about a sense of peace from the movement.

Using one particular sound on a loop, this type of meditation is designed to clear the mind. This could be through repeating a word or phrase over again or humming the “Om” sound. It is thought that practicing mantras helps a person become more in tune with their surroundings, enhancing awareness.


Studies have investigated the effects of transcendental meditation on things such as anxiety and found that it can help those suffering from the condition find relief from their symptoms.It involves similar techniques to the mantra type of meditation; however, the mantra chosen here is more unique and specific to the person practicing.


This type of meditation is also referred to as the body scan, because it involves tightening and relaxing one part of the body at a time. The goal of progressive meditation is to help relieve physical tension.


Loving-kindness meditation is exactly as it sounds in the sense that the practice revolves around both sending and receiving love and kindness. The goal is to promote compassion, love, and acceptance towards others as well as oneself.


This type of meditation relies heavily on the imagination and is performed by visualizing positive images in the brain using all five senses. It is designed to promote relaxation, peace, and calmness.

What are the long-term effects of meditation?

Practicing meditation over a longer period of time is the best way to reap the benefits of the techniques. There are multiple different health effects of meditation, both physical and mental.


Meditation has long been thought to be a helpful aid in reducing stress and promoting relaxation. However, it has also been proven to help in the treatment of mental health conditions such as anxiety and depression.

Other mental health benefits include a high self-awareness, enhanced compassion and kindness, and higher levels of empathy. Transcendental meditation, in particular, has also been found to help combat addiction.  


Practicing meditation regularly can lead to many physical health benefits. One such benefit is better sleep. Research has found that those with insomnia who practiced meditation found relief from their condition and a better night’s rest.

Meditation has also been shown to help elevate brain activity and improve cognitive functions such as memory, attention span, concentration, and executive function in the brain. It does this by positively changing both brain function and structure.

Studies have also shown that meditation regularly could help those with chronic pain alleviate their symptoms. Meditation has also been linked to a decrease in blood pressure in those with high blood pressure.

Meditation and immune health

Another of the physical health benefits of meditation is that it can help with the health of the immune system. Practicing meditation, specifically mindfulness meditation, can help to modulate immune system function. Certain processes (such as the proinflammatory response, cell-mediated defense, and enzyme activity) have been shown to be positively influenced by regular practice of meditation.

Meditation also lends a hand in immune health because of the effects it has on overall stress levels throughout the body. Since chronic levels of stress can wreak havoc on the way the immune system functions, and meditation can improve stress levels over time, it indirectly leads to a better-functioning defense system.

The many health benefits of meditation have been studied rigorously in recent years, and for good reason. The practice is a proven technique that people of all ages and backgrounds can utilize on the road to better physical health and mental wellbeing.

14 Immune-Boosting Winter Foods To Fight Off Illness

The immune system can always use an extra boost, but that is especially true in the winter months. During the winter, colds and flus typically affect people in higher numbers because people are more likely to stay in enclosed spaces for longer and because viruses thrive in the cold, low-humidity conditions.

Making sure your immune system is up to par when flu season rolls around is crucial to warding off illness and keeping yourself healthy all year round. There are plenty of things you can do to stay on top of your immune function – including eating some immune-boosting winter foods.

What are home remedies to boost your immune system?

There are a few things you can do for your immune system that require little effort and can be done from the comfort of your own home. Getting enough quality sleep is vital to immune health because the less quality sleep a person gets, the more likely their immune system will weaken, leaving them open to illness.

Moderate exercise is also a great way to help improve the functionality of the immune system. Research has shown that people who engage in moderate exercise regularly, such as brisk walking, jogging, swimming, light hiking, and biking, show an improvement in the way their immune system functions. The one caveat is that the activity shouldn’t be too intense, as intense bouts of exercise can actually suppress immune function.  

Staying hydrated is also a simple way to keep the immune system up to par. Dehydration can cause a variety of ailments such as headaches, mood imbalances, and heart and kidney issues, and when the body is fighting to stay healthy on its own, it has a hard time fighting off pathogens. It’s also worth noting that keeping stress levels down can have a positive effect on immune function. You can reduce stress through relaxation exercises such as meditation or yoga.

What foods boost your immune system when sick?

Diet is the best way to ensure that your immune system is running at its best. If a cold or flu has already taken hold of your body, there are specific foods that can lessen the duration and severity of the illness by boosting your immune function and getting you back to health.

  1. Broths. Broths are great when you’re sick because they keep you hydrated, are easy to stomach, and contain vital nutrients that the immune system needs to be ready for battle.
  2. Garlic. Garlic has both antibacterial and antiviral effects, so it’s a great addition to your diet if you’ve caught a cold. It has been shown to help stimulate the immune system.
  3. Honey. Honey is full of antimicrobial compounds, which give it antibacterial effects. This has led to honey being used to help people ward off illnesses and get over common flus and colds.
  4. Oatmeal. Oatmeal is bland enough to eat while sick but also packs a punch when it comes to helping you get over that pesky cold. Oats contain beta-glucans, which stimulate the immune response.
  5. Berries. The immune-boosting effects of berries come from polyphenols, a type of antioxidant.
  6. Green leafy vegetables. Green leafy vegetables such as spinach have vitamin C, beta carotene, and antioxidants. When consumed regularly, they can give the body a better chance at fighting off infection.  
  7. Citrus fruits. Citrus fruits are full of vitamin C, a vital nutrient for immune health. The vitamin plays a role in the production of white blood cells, which are responsible for fighting off infection. Having more white blood cells will make the immune response stronger.
  8. Yogurt. Natural yogurt is high in vitamin D, a nutrient that helps regulate the immune system and its response to outside invaders.Vitamin D can also be found in supplement form, and in Vital RX’s Immune Health Subscription Box.
  9. Bell peppers. Bell peppers have both vitamin C and beta-carotene, two crucial nutrients for optimal immune health.
  10. Sunflower seeds. Sunflower seeds are a great immunity booster because they are full of nutrients that help immune function, such as vitamin E, vitamin B6, and magnesium.
  11. Kiwi. When the body is fighting off an infection, it needs all the nutrients it can get. The kiwifruit is a superfood of sorts and is full of essential nutrients such as folate, vitamin K, and vitamin C.
  12. Almonds. The immune system requires vitamin E to do its job; almonds are packed with this nutrient.
  13. Papaya. Another vitamin C-packed fruit that you can eat while sick is papaya. The fruit also contains a specific digestive enzyme known as papain that lowers inflammation throughout the body.
  14. Shellfish. Shellfish may not be your first thought when considering immune-boosting foods, but they are a great food to eat when sick. This is because they have a ton of zinc, a mineral that helps immune cells function properly.

This list, although not exhaustive, is a great place to start when thinking about boosting your immune system this winter. The important thing to remember is the vital nutrients that are needed to help ward off infection and keep the immune system running strongly.

Specific nutrients that are vital to immune health include:

  • Vitamin C. (Spinach, kale, strawberries)
  • Vitamin E. (Nuts, seeds, oils)
  • Vitamin A. (Carrots, sweet potatoes, butternut squash)
  • Vitamin D. (Salmon, tuna, fortified cereals)
  • Folate/Folic acid. (Enriched foods such as pasta, bread, and rice)
  • Iron. (Red meat, chicken, turkey, beans, broccoli)
  • Selenium. (Seafood, poultry, cottage cheese)
  • Zinc. (Baked beans, yogurt, chickpeas)

The Importance Of Vitamin D3 In Immune Health

Immune health is a vital component of overall health. In fact, without the immune system functioning at its best, all other systems in the body would falter in the presence of pathogens that have made it through due to a lack of proper immune response. When the body is able to fight off infection properly, it leaves all the body’s other systems to do their respective jobs and maintain a consistent level of wellness.

Many vitamins play a role in immune health, but some are more important than others. For example, vitamin C is often hailed as a great immune booster, but it’s not the be-all-end-all when it comes to keeping immune function running as it should. Vitamin D3 is one such vitamin that is a great immune assistant, but doesn’t get talked about as often as it should when it comes to the vitamins that keep the body’s defenses up to par.

What is the role of vitamin D in the immune system?

Vitamin D has a direct role to play in bone homeostasis and the way the body absorbs calcium, but that’s not the only thing it can do. Studies have shown that the nutrient can also help regulate both the innate and adaptive immune responses in the body by acting as an autocrine signaler for B and T cells and antigen-presenting cells.  

When it comes to protective immunity, vitamin D has been shown to be a great assistant. Prior to the use of antibiotics on tuberculosis, some patients were seeing great improvements in their conditions after exposure to sunlight. Doctors had assumed that sunlight killed TB; however, it is now thought that the increase in vitamin D levels was the catalyst for healing.

It has also been found that a deficiency in vitamin D can lead to increased risk for developing autoimmunity, the process that occurs when the body signals an immune response to its own cells that pose no threat. Not having enough vitamin D can also lead to a higher risk of frequent infections. 

Vital RX - bone health

What are the benefits of vitamin D?

Vitamin D isn’t just good for bone health and the immune system. According to studies, the vitamin can actually help ward off further diseases, including decreasing the risk of developing heart disease, multiple sclerosis, and the flu. It has also been shown to help fibromyalgia patients manage their symptoms.

Those who suffer from depression may also see an improvement in their symptoms if they increase their levels of vitamin D. Research has shown that the nutrient acts as a mood regulator, and that those who took vitamin D supplements during treatment for their mental illness saw a higher reduction in negative symptoms than those who did not. Vitamin D deficiency is also common in those who suffer from anxiety.

Another novel benefit of vitamin D is weight loss. One study found that weight loss group participants were able to see a larger reduction in weight when they added both calcium and vitamin D supplements to their regimen. It was suggested that this is because the supplements acted as appetite suppressants, leading to less consumed calories and more weight lost.

Does vitamin D help with illness?

As mentioned above, vitamin D holds a myriad of different health benefits when it comes to illnesses such as declining mental health, heart disease, and the common flu. This is due to its ability to help activate immune markers and keep the body free of pathogens.

In the current state of the COVID-era world, ensuring the body has enough vitamin D has never been more important, primarily due to its ability to keep the immune response functioning as it should. In terms of common illnesses such as colds and flu, many studies have evidenced the role of vitamin D as both a preventative method as well as a treatment. Other chronic health issues could also benefit from vitamin D, including heart disease, certain cancers, autoimmune disorders, and diabetes.

How much vitamin D should I take for immune system health?

The amount of vitamin D you take for your immune system will be entirely dependent on your current levels. It’s always important to assess how much you need prior to beginning a new supplementation plan. That being said, there are general amounts that can be taken to ensure that you’re getting enough and not becoming vitamin D deficient.

For adults, between 600 to 800 IU per day should be an adequate amount, whereas children would need between 400 and 600 IU per day. Those deficient in the nutrient may need to begin with more supplementation to return to healthy levels. For people with bone health disorders, more vitamin D may be needed to ensure that calcium and phosphorous are being absorbed thoroughly enough to manage symptoms.

What’s Included In Our Immune Health Subscription Box (And Why)

In the wake of the COVID-19 pandemic, immune health has never been more important. The immune system is the body’s first line of defense against any pathogen, and when it’s not functioning as it should, the body is more susceptible to illness. Often in modern-day living, the immune system is one of the first parts of the body that suffers from a lack of good nutrition, adequate exercise, and an increase in pollutants and toxins.

When diet isn’t up to par, many people choose to supplement for an increased boost in immune health so that if an illness does happen to invade, the body has a better chance of fighting it off quickly and efficiently. The popularity of the wellness subscription box (and more specifically, the immune health subscription box) is proof that people are looking for better ways to improve their immune system during these trying times.

What is immune health?

Immune health is the body’s capability of fighting off or resisting an invasion on a multicellular level. It is driven by T-cells, and there are two types of immune responses: innate and adaptive. The innate part of the immune system is non-specific in nature, so its defense is generalized to all pathogens, whereas the acquired immune system practices immunological memory. The cells responsible for the acquired immune response often remember pathogens that have entered the body by creating antibodies to target specific invaders. The two systems work together against germs or other substances that come into contact with the body.

How can I boost my immune system fast?

For those who suffer from a weakened immune system, it can be hard to correct because the system isn’t a single entity. It relies on several different things to work symbiotically for it to function the way it should.

It can be hard to boost the immune system quickly, but there are ways to keep it healthy. The best way to keep things running smoothly is through diet and exercise. Other forms of immunity protection include:

  • Avoiding toxins such as cigarettes and alcohol.
  • Getting enough sleep.
  • Practicing good hygiene to avoid exposure to harmful infections.
  • Managing stress levels.

What foods increase immunity?

For a fighting chance against pathogens and other bacteria, the immune system relies heavily on nutrition. Many foods contain vitamins and minerals that can aid in the protection of the immune function and should be consumed regularly for full effect. These foods include:

Fermented or probiotic foods

Foods such as yogurt, sauerkraut, kimchi, and kefir can help to replenish the stomach with good bacteria. Research has shown that when the gut bacteria is balanced properly, the immune system has an easier time telling healthy cells and invader cells apart. 

Healthy fats

Inflammation can lead to a suppression in immune function, and research has shown that eating healthy fats can reduce widespread inflammation. Foods such as avocado, salmon, and extra-virgin olive oil can all be a great addition to your diet if you want to reduce inflammation and strengthen your immune system.

Whole foods

Plant-based foods are full of nutrients the body needs. They are also full of antioxidants that can lessen the risk of oxidative stress, and thus keep the immune system running optimally.

Foods low in added sugar and carbs

Refined carbs and sugars can lead to obesity if consumed in high amounts. Being overweight or obese can significantly decrease your body’s ability to fight off infection.

Vital RX Immune Subscription Box

To help strengthen a struggling immune system, an immune health subscription box like the one offered by Vital RX is the perfect addition to a healthy lifestyle. The high-quality ingredients in the box have been curated by specialized doctors to create an immune supplementation package that really works.

Thymosin Alpha

Oxidative damage and other chronic health issues can lead to a significant risk of a weakened immune system. The peptide thymosin alpha can restore the immune function by stimulating pathways that help to signal cells and increase production of cytokines, a group of small proteins that assist in cell signaling.  

Research has also shown that the peptide can play a vital role in the efficacy of vaccines, improvement of chronic fatigue, reduction of oxidative stress, and elimination of unhealthy cells from the body.


CJC is an amino acid peptide hormone that plays a crucial part in protein synthesis throughout the body. It can assist in overall wellness by improving sleep quality and promoting an increase in overall energy levels. When it comes to the immune system, the CJC has the ability to lend a hand by increasing the secretion of human growth hormone (HGH). HGH has a direct role in the effect the immune system has on pathogens, since it can lead to a more efficient stimulation of both B and T cells that help fight off infections. 

Multicomplete 360

The body needs all the essential vitamins and minerals it can get, and if your diet is lacking, a multivitamin can pick up the slack. Included in the Immune Subscription Box is Vital RX’s Multicomplete 360 to help balance out any deficiencies that may be leading to a suppressed immune function.

Vitamin D3

Vitamin D3 is an essential part of overall health, and is especially important when it comes to the body’s ability to absorb calcium and phosphorous. Without adequate D3 levels, the body will not be able to use the vitamins it needs and thus could suffer from weakened bones and loss of bone mass. Vitamin D3 plays a vital role in immune health because of its effect on immunologic cells. It acts as an autocrine to help modulate both innate and acquired immune responses.

Why Immune Health Subscription Boxes Are Surging In Popularity In 2020

Flu season has begun, and with the current state of the COVID-19 pandemic, the ability to ward off seasonal sickness is more important than ever. The current viral spread and possible grave repercussions of contracting coronavirus also has many people exploring preventive medicine options, as opposed to focusing on recovery if they do fall ill.

Since viruses are not treated with antibiotics due to increased risk of complications, this leaves the bulk of the recovery up to your immune system if you happen to catch COVID-19 or even the seasonal flu. But what can you do if your immunity isn’t functioning as it should? The solution to this modern 2020 problem could be as simple as a monthly immune health subscription box. People use them for all sorts of products from dog toys to clothing, but this year, a monthly investment in health is becoming all the rage.

What causes a weakened immune system?

The immune system can falter for a variety of reasons. Poor diet, lack of physical exercise, chronic disease, and even long bouts of emotional or physical stress can lead to weakened immune function. This is not good for those wishing to beat the winter illness that affects millions of Americans each year. But the upside to having a less-than-adequate immune system is that with the right lifestyle changes, it’s not likely permanent.

The most effective way to boost immunity is by getting a vaccine. This helps immune cells to identify specific pathogens as they enter the body, while also equipping them with the memory they need to fight them off. But when a vaccine hasn’t been created, as is the case with COVID-19, there’s still hope in the battle of combating the virus.

How to boost your immunity

Exercise is great for overall health, but it can also lead to a better response in the innate and adaptive immune systems, which increases one’s ability to fight off viral infection if it does happen to infiltrate the body. Antiviral foods are also a huge assistant when staying healthy all the way through flu season.

The foods that are hailed best in show when it comes to viral protection include:

Vitamins that have been shown to help support healthy immune function include vitamins A and D. Research found that these can lead to a better immune response because of their ability to help modulate the immune system response and increase the production of lymphocytes, the antibody isotypes.

The concept of the immune support subscription box is the same as any other monthly or quarterly subscription. Customers can sign up and continue to receive regular products so that they always have access to what they need, when they need it.

Health subscription boxes are rising in popularity this year. The pandemic has shed a light on unhealthy lifestyles and how important it is to maintain overall wellness at all times. Specifically, the immune health subscription box has popped up everywhere because of the aforementioned inability to fight off viral infections without a healthy immune response.

Vital RX Immunity Health Box

The Vital RX Immunity Health Box has been carefully curated with ingredients proven to assist in the overall healthy function of the immune system. The box features a variety of different products to be used in conjunction with one another to boost immunity throughout flu season, while the risk of transmission of COVID-19 is still high, and all year round.

To help assist with immune health, the box contains products with powerful antioxidants, peptides, and a daily multivitamin to help achieve year-long overall health. CJC is an amino acid peptide hormone that encourages protein synthesis by improving sleep quality and increasing energy. The Multicomplete 360 balances everything you need in a day and packs it into one, while the addition of vitamin D3 gives the body what it needs to properly absorb essential nutrients. The box also includes thymosin alpha.

What is thymosin alpha and what does it do?

This synthetic amino acid peptide activates certain cells within the immune system to help people with weakened or impaired immune responses build their ability to fight off infection. The peptide’s ability to modulate certain responses within the body gives it its potent antiviral properties, and it has been used to treat various ailments such as chronic inflammatory autoimmune diseases.

Other uses of thymosin alpha include:

  • Improving chronic fatigue
  • Protecting against oxidative damage
  • Suppressing the growth of tumors
  • The detoxification of unhealthy cells within the body

Thymosin alpha has also shown to improve the efficacy of vaccines, so for those who do intend to get the flu shot, it can help increase how well the shot works as a supplemental form of protection.

5 Ways To Enhance Your Natural Immunity

Your immune system is your first line of defense against pathogens and other threats to your health. During fetal development, the immune system starts to mature, with B series lymphocytes being present in the liver by nine weeks. Following birth, both the innate (against non-self-pathogens) and adaptive (immunity that develops over time) immune systems need time to progress to the full level of protection. By the time a person reaches eight or nine years old, they will have a good indication of how well it works to battle illness.  

Having a functional immune system is vital to staying healthy throughout one’s life, but it can be compromised by certain factors such as poor diet, lack of exercise, inadequate sleep, and the contraction of certain diseases. When one catches an illness, that’s where natural immunity comes into play. Knowing how to support your immune system naturally is a great step on the road to a healthier you.

What is natural immunity?

The process of natural immunity can only occur once a person has contracted a certain pathogen. The immune system targets a threat and creates antibodies to battle against the specific disease cells in an attempt to rid the body of them, and to be ready if it happens to show up again in the future. The specialized antibodies will then be present with only one job to do: recognize and protect against the specific illness they were created for.

For example, a chicken pox infection relies heavily on natural immunity. That is why it’s unlikely for a person to develop the disease twice, even if the virus infiltrates the body more than once. The antibodies are in wait to ensure that it doesn’t make you sick a second time.

How can I increase my immunity naturally?

There are many ways to help increase the function of the immune system to help protect against certain diseases and illnesses. Although immune systems develop based on exposure to pathogens, natural immunity protection, and the environment in which they were developed, they are not always stuck functioning at the same level throughout one’s life.  


Adequate sleep is important for all aspects of life. Giving the brain time to rest, reset, and process activities is important to cognitive function, memory, and the clearing out of toxins that may have built up over the previous day. It’s not just the brain that requires sleep – studies have shown that every process and part of the body relies on shutting down for the night to help reinvigorate it so it can run properly the following day. Being without adequate quality sleep can lead to cognitive decline, increased risk of heart disease, and high blood pressure.

When it comes to the immune system, sleep plays a direct role in the production and function of T-cells and cytokines. One study has suggested that during sleep, the body extravasates immune cells throughout the body to help give the immune function a better chance at responding to pathogens. It can also help with immunological memory, which gives antibodies the ability to recall certain threats and fight them accordingly. 


The act of mentally training your body to respond to certain experiences can lead to a decreased level of anxiety, but some studies suggest that it can also help with immunity. It has been found that meditation can lend a helping hand when it comes to lessening inflammation that may be detrimental to immune function; slowing the process of aging, which affects how the immune system functions; and activating T-cells.

Nutrition and hydration

Nutrition and hydration are both key elements when it comes to healthy living. Giving the body the proper amount of nutrients, vitamins, and water is a vital component in ensuring that all systems are running at their best.

When it comes to immunity, nutrition and hydration can have a huge impact. Many foods can help boost the process of fighting against pathogens because they improve the activation of pathogen-fighting cells. No one nutrient can lead to the improved function of the immune system, but a varied diet full of vitamin C, vitamin D, zinc, selenium, iron, amino acids and protein can help prepare cells for battle and curb inflammation that may make it harder for your immune system to respond to a threat.


Regular exercise is an important part of immunity because it can help improve cardiovascular function and increase circulation throughout the body. When circulation is improved, cells are able to travel freely at a much higher rate. This, in turn, leads to their advanced ability to be where they need to be when fighting off infection and disease.

There have been many studies on the effects of exercise and the immune system. One in particular found that acute and regular exercise could have a direct impact on the body’s immunosurveillance response, along with its ability to improve the microbiota, which in turn positively impacts the body’s immune response.

Social interaction

It might not appear to have a huge impact on health, but studies have shown that social interaction can lead to improved levels of mental wellbeing. Not only that, but spending time with loved ones can also improve the immune system by reducing stress levels within the body, thus helping to regulate immune response.

Supplements and peptide therapy

It can be difficult to get all the required vitamins and minerals through diet alone, and that’s where supplements come in. Since immunity relies on what a person feeds their body, supplementation is required for those who do not get enough on a daily basis. Peptide therapy can also be a good assistant for immunity because it can encourage the development of T-cells.

Vital RX has developed an immune-boosting subscription box that contains an assorted group of peptides and supplements to help keep your immune system running optimally all winter long. The Vitamin D3 promotes the absorption of vital nutrients calcium and phosphorous, and the gluten-free multivitamin acts as your everyday vitamin.

The box also has CJC, a powerful amino acid peptide designed to assist the body in protein synthesis by improving sleep, lessening injury recovery time, and boosting energy levels. Also included is the immune modulator peptide Thymosin Alpha, which leads to a heightened immune function, less overall fatigue, and protection against oxidative damage.
