An excellent immune response is required for optimal health. Your immune system acts as your body’s natural defense against disease, infections, and illness.
Some people have healthy immune systems from birth. Others have healthier lives and consume nutritional meals, which help them maintain natural immunity. Many individuals take supplements regularly to strengthen their innate immunity. Zinc, Vitamin C, plant and herbal extracts, along with the other compounds, have been found, in studies, to boost immunological function.
There are countless products available today that promise to boost your immune function. Most of them, however, are unsuccessful. We spent hundreds of hours looking for the ones that function. Continue reading to learn about the most excellent immunity booster in 2021.
13 Best Immune Boosters in 2021
To identify the finest immune system support supplements in 2021, our editorial team tested immunity boosters, studied lab results, contacted manufacturers, and conducted rigorous due diligence. Below are the results of our poll.
VitaPost Immune Support
VitaPost’s Immune Support feeds your immune function with a blend of plant extracts. Immune Support contains vitamins, herbal extracts, and other components that, according to VitaPost, can help support a healthy immune system.
Arabinogalactan, beta-glucans, quercetin, vitamin C and E, green tea, and other traditional and modern ingredients are included. Some of these chemicals boost immunity by supplying antioxidants to the body.
Other ingredients work by concentrating on different aspects of the immune system. VitaPost Immune Support has over a dozen proven components in each capsule, making it among the prominent immune support supplements on the market today. Additionally, it’s one of many products on this list with the best value for money. A bottle costs under $14.
Mushrooms are an unexpectedly effective immune booster. Studies have indicated that mushroom extracts can assist with tiredness and cognitive decline. Mushroom extracts are incorporated in many trials to improve memory and attention.
Others have demonstrated that they help with memory. Mushroom Defense’s creators claim that their supplement will defend you from bacterial and viral dangers while boosting your energy and intellect.
Bolstered by a 67-day full refunding policy, Mushroom Defense combines ingredients not commonly seen in similar mushroom-based supplements, such as Agaricus blazei, a rare and unique mushroom extract from a Brazilian mountain village near Sao Paulo.
The remaining mushroom extracts in Mushroom Defense include clinically analyzed mushrooms like turkey tail, lion’s mane, reishi, chaga, shiitake, Cordyceps Sinensis, and maitake. If you trust the efficacy of mushroom-based extracts for immune support, then Mushroom Defense’s immunity strengthening complex may be your leading choice.
VitaPost Immune Complex
Immune Complex from VitaPost has many similar characteristics as seen in Immune Support, like proven ingredients and a fair price; however, it works differently to support the immune system. Elderberry, echinacea, and other probiotics are included in this recipe, different from Immune Support’s ingredients.
These are some of the best-known immunological boosting compounds from nature. Elderberry has been shown in studies to shorten the duration of cold and flu symptoms. Many people use echinacea for similar reasons.
Probiotics are a source of good bacteria that live in your gut and create immune systems. VitaPost’s Immune Complex supports digestive health because the gut hosts roughly 70% of the immune system.
Zenith Labs Nano C
Zenith Labs’ Dr. Ryan Shelton created Nano C Immune Support, another vitamin C supplementation. Vitamin C is present in almost all supplements on this list. Dr. Shelton made a tincture that contains bioavailable forms of class C vitamins.
You use Nano C drops daily to boost your immunity by providing your body vitamin C in one substantial dose. Nano C produces 1,000-fold smaller “nano” forms of C vitamins than naturally produced vitamin C.
This means that your body will be capable of absorbing it more effectively, allowing these vitamins to reach your bloodstream quicker and more efficiently, supplying energy to the cells in your immune system. Nano C, Dr. Shelton says, will stimulate antibody formation, strengthen immune function, and assist in faster recovery from bacterial infections and viruses, among several other things.
Simple Promise’s Epishield Plus is an entirely natural product that promises to boost immunity in only two hours. This supplement contains various ingredients, including mushroom extract and vitamins C and D, among other elements. Additionally, Epishield Plus includes fermented yeast, which is uncommon in supplements.
Because the fermented yeast in Epishield Plus is supposed to help keep the immune system healthy and reliable. Priced at $50 a bottle, Epishield Plus is often a popular and common choice.
Only two products on our list include EpiCor, a fermentation of dry yeast manufactured from the Saccharomyces cerevisiae. Although many other immune booster supplements contain vitamins C and D and mushroom extracts, Epishield Plus stands out for its novel usage of fermented yeast extract.
Advanced Bionutritionals Resistol
Advanced Bionutritionals promote Resistol as a way of supporting healthy immune function. Eleuthero, Andrographis, Platycodon, licorice, and prickly chaff flower are the supplement’s five supporting plant extracts, among others. These five components have been investigated for their immune-boosting properties, and many individuals take them regularly for immunological support.
The immune supplements described below are high in vitamin D, vitamin C, and other essential vitamins. Advanced Bionutritionals takes a different approach to supplement development, including plant extracts and herbs not included in most other products.
Resistol may be the correct choice for you if you believe in the ability of Andrographis, Platycodon, and eleuthero to promote immune function. And, at less than $30 for a bottle, it’s a bargain compared to other products on this list.
Organixx 7M includes mushroom extracts as well as other substances that boost the immune system. Three of the most popularly used and proven mushroom-based extracts for immunity are all included in this formula. They are maitake mushroom extract, shiitake mushroom extracts, and reishi mushroom extract.
These different mushroom extracts’ beta-glucans are claimed to have antioxidant and anti-inflammatory properties. Along with the three listed mushroom extracts, Organixx 7M includes turkey tail extract, lion’s mane, cordyceps, which are known to improve immune function.
Organixx suggests using their supplement regularly to improve inflammation, good digestion, and immune function while guarding against ailments.
All of the top immune support products on this list have been recommended by doctors. Some of them are created by medical physicians or other immunological experts. BioShield MD supplement promotes natural energy, immunity, mental health, and joint health, among other benefits.
Dr. Mark Rosenberg from SunCoast Sciences created this recipe intended for optimum absorption and therapeutically effective doses. BioShield MD is one of our favorites since it contains the most influential and well-researched immunity substances in the appropriate quantities.
Rather than overloading the body with hundreds of compounds at low doses, BioShield MD focuses on substantial quantities of cocoa extract, sour cherry extract, curcumin, quercetin, green tea extracts, and resveratrol, among others. Flavonoids and antioxidants are abundant in BioShield MD’s ingredients, which can aid immune function in various ways.
VitaPost Turmeric and Ginger
VitaPost’s Turmeric and Ginger is the third and final VitaPost supplement on our list, a premium mix containing BioPerine. BioPerine promotes healthy immune systems as well as joint health by filling your system with antioxidants. Many people use ginger and turmeric pills regularly to boost their immunity and general health. In the immunity community, they’re two of the most popular superfoods.
You may use ginger and turmeric to boost your immune system with VitaPost’s Turmeric and Ginger. Turmeric and Ginger by VitaPost include 500mg pure turmeric and 100mg ginger in every tablet. To help your body’s absorption, there’s a 50mg turmeric dosage with 95% curcuminoids as well as 5mg extract from black pepper.
VitaPost’s Turmeric and Ginger is among the best available alternatives if you’re looking for a ginger and turmeric supplement that takes a no-nonsense approach to enhance your immune function at a fair price.
Immuno Defense 4x
Quercetin, EpiCor, Vitamin D3, and bromelain are the four sole components in JayLab Pro’s Immuno Defense 4x to promote immune health. Immuno Defense 4x, like the other top-ranked choices on our list, focuses on giving higher doses of limited numbers of components instead of lower doses of a considerable number of compounds.
Immuno Defense 4x isn’t the cheapest immune support supplement on this list, but it’s also not the most costly either, at about $45 per bottle. It’s also the second product on our list to contain EpiCor, an extract from dried yeast that’s been researched for its many immune-supporting properties. Each dosage contains 500mg of EpiCor and 500mg of quercetin and high levels of bromelain (150mg) and vitamin D3 (166 percent DV).
Q-Ion Immune Defense By Doctor G’s Naturals
Doctor G’s Q-Ion Immune Defense is one of a few products on this list that promises to be practitioner-approved, implying that at least one medical doctor has authorized it to boost immune function.
Q-Ion Immunological Defense’s creators claim that their mixture is a potent anti-inflammatory product that promotes immune health and antiviral activity. This supplement also promises to help protect your body from infections, which is a claim made by just a few other immune supplements on our list.
Doctor G’s Naturals is a supplement company created by Dr. John Gordon, a certified physician. Using his medical experience, Dr. Gordon supplemented his Q-Ion Immune Defense formula with quercetin, green tea extracts, bromelain, and zinc. Ion-Blast Technology is also included in the formulation, which improves the digestibility of the zinc and quercetin in the combination, allowing your body to absorb the compounds more efficiently and rapidly than usual.
Immunity 911, as per PhytAge Labs, has the highest concentration of crucial immunity-boosting ingredients, making it ideal for preserving your body’s natural safeguard of defense against illness. Notwithstanding PhytAge Labs’ strong medical claims, Immunity 911 seems to have an extensive range of attributes (over 20 in every capsule).
However, the doses are not relatively as high as those of some other products on our list. PhytAge Labs claims that the components in Immunity 911 are proven to work and even guaranteed. The supplement has lower doses of vitamins C (33% DV) and E than the other products on our list (133% DV).
However, the first three components are red raspberry, green tea, and Graviola leaf extracts. The patented recipe comprises many of them in higher doses than most other products. Immunity 911’s assured health claims are challenging to evaluate because of their lack of clear labeling. PhytAge Labs is confident that its approach, which contains herbs, mushroom extracts, and superfruits, works.
Immunity Formula’s Immune Support
Immune Support by Immunity Formula is a therapeutic-grade herb essential oil mix that aids in the treatment of a variety of immunological and viral problems. Immune Support can enhance your natural viral defense, boost your immune system, sanitize any surface, and purify and disinfect the surrounding air, along with other benefits.
To receive the advantages of these essential oils, take Immune Support regularly. Essential oils such as lemon, peppermint, oregano, cinnamon, and turmeric are beneficial to the immune system.
Immunity Formula’s Immune Support oil, unlike other supplements, has the convenience of being distributed or topically applied to your skin. The Immunity Formulas Immune Support may be the ideal choice for you if you want to breathe in an immune supplement rather than absorb it through your skin.
How We Ranked The 13 Best Immune Boosters in 2021
All immune support products promise to help the body’s immune system work properly. Some have substances that have been proved to work. Others include strange plant extracts that have only a few scientific studies to back them up. The following ranking criteria were used to distinguish the best and worst immune support supplements:
Ingredients that have been scientifically proven
Significant scientific data support the use of vitamin D, zinc, vitamin C, probiotics, and elderberry extract. These components have been demonstrated in several studies to help with immunity in a variety of ways. Supplements with scientifically established ingredients linked to immunity and immunological function were our favorites.
Doses that work
Some immune support pills include the correct components but at incorrect doses. For example, some supplements have hundreds of components, yet none of the dosages are strong enough to affect immunity. We chose products with high, scientifically confirmed doses of all mentioned components.
Honest Health Advantages
Supplements are not allowed to promise to cure diseases or enhance your health under FDA rules. They may only state that they are in favor of health. Many immune booster pills have even dropped the word “booster” from their titles.
Other immune supplements promote themselves as virtual cure-alls, claiming to heal illnesses, prevent COVID-19, and give a slew of other advantages. These are unsubstantiated and dishonest allegations. We stayed away from supplements that made false promises.
Location of Production
We recommended immune support supplements manufactured in licensed and accredited institutions. Some firms get their ingredients from low-cost sources in other countries. Others rely on local facilities that have been licensed by the Food and Drug Administration (FDA) and other national regulatory bodies. The more openness in the production process, the better.
Board of Medical Advisors
Doctors at the finest supplement businesses lead medical advisory boards. Each recipe is reviewed or created by this medical advisory board, who use their medical knowledge to produce the most refined immune-boosting mix possible. Some supplement businesses lack a medical advisory board or any specialists on staff, making their compositions less trustworthy and effective.
The reputation of the manufacturer
Some manufacturers have launched immune support supplements to make easy money. This has become especially common during the COVID-19 pandemic. We preferred manufacturers with a long and established reputation for offering honest, effective immune support supplements while maintaining high levels of transparency.
Sources of Ingredients
Some immune boosters contain rare mushroom-derived extracts and other mixes that you don’t find in other supplements. Nutritional supplements with transparent and reliable ingredient sources were our favorites.
Value and Price
Some people are willing to pay $10 on a vitamin that will help their immune system. Others are looking to pay $100. We provided a selection of immune booster supplements in various pricing ranges, emphasizing high value at all prices.
Immunity Booster Side Effects
If you’re a healthy adult who isn’t on any medicines, you’re unlikely to suffer any side effects if you follow the dose directions on your immune support supplement. Nutritional supplement manufacturers are required by law to utilize substances and doses that are Generally Recognized as Safe (GRAS) by the Food and Drug Administration.
When taken in regular doses, these substances are safe for humans to consume. This is the list that all respectable supplement businesses follow. After people begin taking immune boosters for the first time, they could suffer bloating, stomach pain, or indigestion.
Some people have difficulty breaking down the chemicals in capsules and tablets. However, you should consult a doctor before using any supplement, particularly if you suffer from medical conditions or are currently taking medications.
Immune Boosters: Scientific Evidence
For general health and wellness, your immune function is critical. Specific vitamins, fruits, plant extracts, herbs, and minerals have supported immunologic functions in studies. Consuming these foods can help the body’s natural ability to defend itself against aging, diseases, and illness.
That’s why many individuals use immune support vitamins regularly. Following a healthy diet and maintaining a healthy lifestyle are two of the most effective strategies to strengthen your immune system. Immunity may be boosted by eating a well-balanced diet, drinking plenty of water, getting plenty of sleep, and emphasizing exercise.
If you eat poorly or have a sedentary lifestyle, your body will be unable to defend itself. Similarly, your immunity might be weakened by a variety of factors. A bad diet, particularly one high in sugar, can severely reduce your immunity.
Smoking, excessive alcohol use, poor sleep patterns, dehydration, obesity, stress, and insufficient exercise routines can weaken your immune system.
Vitamin C is among the most often used immune support products. Vitamin C has been proven in several studies to improve immunity in a variety of ways. As a result, vitamin C is found in many of the supplements listed above.
Vitamin C is required by the body to produce collagen, L-carnitine, and some neurotransmitters, say the National Institutes of Health. It’s also vital for the formation of connective tissue, which influences wound healing. Vitamin C is also an antioxidant, meaning it fights disease-causing free radicals all over your body. Vitamin C has even been proven in specific trials to prevent or postpone the development of some malignancies.
According to studies, persons who suffer from vitamin D deficiency have much worse immune responses than those who obtain necessary daily doses. Autoimmunity and an increased risk of illness, particularly the flu, are connected to vitamin D deficiency. Before the advent of antibiotics, medical practitioners used vitamin D to cure diseases, including TB. Vitamin D may be obtained from a variety of foods. Vitamin D3 from the sunshine can also be converted into usable vitamin D by your body.
The majority of the immune booster supplements listed above are protein-free. Protein is vital for the immune system. Amino acids are the building blocks of protein, and your immune system relies on them for sustenance.
Fish, chicken, beef, pig, eggs, yogurts, almonds, beans, and soy are excellent protein sources. Protein is very crucial for maintaining immunity in your intestinal cells. Your gut contains 70% of your entire immune system, and protein can help to promote immunity from the digestive system to the rest of your body.
Many people use zinc supplements regularly to boost their immunity. Zinc is a vital mineral that we obtain through our diet. Zinc insufficiency, like vitamin D deficiency, is linked to a weakened immune system.
According to studies, persons who are deficient in zinc have a higher chance of contracting infectious illnesses. Zinc has antioxidant and anti-inflammatory properties, and even the slightest zinc deficiency can lead to immunological failure. You might consider taking a zinc supplement if you don’t receive enough zinc through meat, oysters, nuts, or whole grains in your diet.
In recent years, probiotics have become prominent supplements among immune support products. According to studies, the gut contains 70 – 80 percent of the cells that make up your immune system. If you neglect your gut health, your immune system may suffer. Probiotics have been associated with immune-related illnesses and viral infections in other studies. Probiotics have even been found in other trials to help cure and prevent seasonal allergies.
Outside of Europe, elderberries aren’t well-known, but that’s changing quickly. An increasing number of individuals are using elderberry for its medical and health advantages. It’s been used as a home treatment for cold and flu symptoms in Europe for generations.
Several European doctors are now recommending elderberry extract to speed up recovery from colds and flu. According to scientific studies, elderberry extract contains high amounts of vitamin C, making it a potent immunity booster. In one investigation, 60 individuals received 15mL of elderberry syrup four times a day for four days and saw a four-day improvement in symptoms compared to a placebo group.
Echinacea has been utilized as a medicinal herb for ages, like elderberry and other components in this article. Echinacea’s function as an immune-supporting component is now scientifically established.
This study discovered that using echinacea for a short time frame might reduce the length and severity of upper respiratory infections and colds. When taken when symptoms first occur, echinacea is helpful, but it appears to be less effective when given later.
Ginger is being used in an increasing number of immune-boosting products. For ages, ginger has been utilized for health and wellbeing in traditional medicine. Ginger’s antioxidant and anti-inflammatory effects are now well understood. Ginger has antibacterial and antiviral effects, similar to garlic. All of these qualities suggest that ginger might be a superfood for immune support.
Turmeric gets recognized for its anti-inflammatory and antioxidant effects. Many individuals use turmeric regularly to boost their immunity. Curcuminoids found in turmeric, like curcumin, have been related to anti-inflammatory effects.
Turmeric’s immunological advantages, on the other hand, may extend beyond its antioxidant qualities. Researchers discovered that turmeric might help the immune system by stimulating various immune cells in this study. Turmeric is also poorly absorbed by the body until combined with black pepper extract (available in supplements like BioPerine), enhancing bioavailability by 2,000 percent.
Finally, there’s a lot of proof that immune support pills have scientific advantages. Multiple studies have demonstrated that the top immune system support supplement components, including those listed above, have been connected to immunity.
Immunity Booster Frequently Asked Questions
Q: What is the immune system’s mechanism?
A: Healthy bodies have immune systems that protect them against harmful chemicals. Your immune function is made up of numerous levels. The primary layers, which act as the body’s first line of defense against infections, include tears and cough reflexes. Foreign invaders are successfully targeted and eliminated by a robust immune system.
Q: What is a T cell?
A: Many immune-boosting products promise to target T cells specifically. T cells assist in the fight against infections in two ways. Helper T cells stimulate B cells, causing them to secrete antibodies and destroy infected target cells. Other T cells are known as ‘killer T cells,’ which target infected cells and kill them without generating antibodies.
Q: What precisely are antibodies?
A: Antibodies are specific proteins that the immune response produces to help your body fight against infections. Antibodies are vital to your immune system’s function. Antibodies are essential for the body’s ability to fight disease.
Q: What is the best immune-boosting vitamin?
A: Vitamins C, D, and E are the most prominent immune-boosting vitamins. Numerous studies have connected all three to immunological function.
Q: What is natural immunity, and how does it work?
A: Innate or natural immunity is your body’s first line of protection against external invaders or viruses. Innate immunity is aided by the epidermis, mucus, and stomach acids. Some supplements promise to target and strengthen innate immunity particularly.
Q: What is an adaptable immunity, and how does it work?
A: An acquired or adaptive immune function pertains to the immune response component that recognizes a virus. Your thymus, spleen, lymph nodes, and bone marrow are in charge of this part of the immune function. These organs and cells generate antibodies when responding to pathogen threats.
Q: Which foods strengthen your immune system the most?
A: Dark chocolate, berries, red grapes, turmeric, leafy greens, ginger, and elderberry are among the most natural foods for boosting immunity. The worst diets for immunity include junk food, foods with extra sugars, fast food, meals containing trans fats and refined carbohydrates (including spaghetti, white bread, pastries, cakes, and cookies), and processed meats.
Q: What meals are the worst for immunity?
A: According to studies, added sugars, fast foods, junk food, meals containing refined carbohydrates (including spaghetti, white bread, pasta, pastries, cakes, and cookies), trans fats, and processed meats are the least beneficial foods for your immunity.
Q: Is it essential for somebody to lose weight to improve their immune system?
A: Studies suggest that people who maintain healthy weight levels have more effective immune functions and responses than overweight people.
Q: What are some of the most efficient ways to strengthen my immune function?

A: As you become older, your immune system weakens. On the other hand, immunity may be altered by exercise, diet, and lifestyle choices, regardless of your age.
Q: Is it true that immune supplements may boost immunity?
A: Even if a supplement does not expressly promise to enhance immunity, it can still help. According to FDA restrictions, supplements cannot promise to enhance immunity, cure disease, or improve your health.
Q: Is exercise harmful or beneficial to immunity?
A: Exercising in moderation is beneficial for one’s immunity. Additionally, those who maintain a healthy weight have a more robust immune system. Therefore, frequent and intense activity might lower your immunity levels if you don’t allow the body time to recuperate.
Q: What role does vitamin C play in immunity?
A: Vitamin C is an antioxidant, which means it protects your body from free radicals. Diseases and disorders are connected to free radicals. According to research, Vitamin C may not eliminate colds or pulmonary infections but may often decrease their duration.
Q: What role does vitamin D play in immunity?
A: Vitamin D appears to have a wide range of effects on your immune system, promoting immunity in a variety of ways. People who are vitamin D deficient have worse immune function than those who obtain the appropriate daily amount of vitamin D.
Q: Is echinacea beneficial to immunity?
A: For ages, Echinacea has been prized for its immune-boosting properties. Echinacea has been proven beneficial when given at the start of cold and flu symptoms in particular research, while other investigations have been less clear.
Q: What role does zinc play in immunity?
A: Zinc is vital for immunity, and studies suggest that taking zinc at the start of symptoms helps reduce the length of colds.
Q: What role do probiotics play in immunity?
A: Probiotics have been scientifically proven to help with intestinal health. Because 70 – 80 percent of the cells comprising your immunity reside in your gut, promoting gut health can assist with immunity. Probiotics, according to this study, can shorten the duration of respiratory infections
Q: Can elderberries be used to boost immunity?
A: Elderberry is a traditional European treatment for boosting immunity. Elderberry is backed by actual scientific data, according to studies. Elderberry, which contains high amounts of vitamin C, appears to shorten the duration of cold and flu symptoms. Elderberry has been shown in studies to be more effective than a placebo in helping people recover from colds.
Q: Does turmeric have any anti-inflammatory properties?
A: Turmeric is high in curcuminoids, like curcumin, which has antioxidant properties. Oxidation has been related to sickness and illness in studies. Turmeric may assist with immunity by reducing inflammation. According to studies, consuming turmeric daily has profound benefits on some people.
Q: What effect does stress have on my immune system?
A: Stress impairs your body’s natural defenses, according to studies. Your immunity is greatly influenced by stress. Cortisol, adrenaline, and other stress hormones are released by the body when it is agitated. Cortisol can reduce inflammation in the body. Chronic stress could raise your risk of health problems by lowering your immunity.
Q: Is it necessary for one to be exposed to germs to boost immunity?
A: Germs are necessary for good health. Your immune system can adapt. When your body comes into contact with something strange, it fights it and remembers it. Your body will know what to do if the material reappears. With measles, we’ve seen that a single infection may protect you for the rest of your life.
Q: Is having allergies a symptom of a weak immune system?
A: Allergies are caused by a faulty immune response. Your body misidentifies something harmless, such as kinds of foods, or pollen, like a sickness. As a result, your body mounts an immune reaction to fight it, which results in you experiencing allergy symptoms.
Q: What exactly are autoimmune diseases?
A: Autoimmunity is a condition in which your body incorrectly recognizes and assaults itself. Your body, for example, is fighting its tissues because it believes they are alien invaders. Autoimmune diseases include multiple sclerosis, lupus, rheumatoid arthritis, and psoriasis.
Q: What effects do vaccinations have on your immunity?
A: Vaccines work by stimulating your immune system to produce antibodies that combat an invading pathogen. Instead of infecting your body, they teach your body resistance against the sickness. The bulk of vaccines are directed towards a particular pathogen component. If you get exposed to the virus later, you will have minimal symptoms if you experience any at all.
Q: Is garlic beneficial to one’s immunity?
A: The active component in garlic, allicin sativum, has antiviral and antibacterial properties against the common cold. Some studies have indicated that garlic provides considerable immunological support, whereas others have found no difference between garlic and a placebo. Despite this, garlic is still among the most often used natural immune boosters.
