Best Immunity Boosters: Review Top Immune System Supplements

Your immune system is your body’s natural defense against illness, disease, and infection.

A good immune system leads to good health. Some people naturally have good immune systems. Others have healthy lifestyle and diet habits that improve their natural immunity.

Today, many people take supplements daily to support their natural immunity. Vitamin C supplements, zinc, herbal and plant extracts, and other compounds are scientifically-proven to support immune function.

You can find hundreds of supplements that claim to support immunity. Unfortunately, many of them don’t work. We did hundreds of hours of research to find the ones that do work. Keep reading to discover the best immunity boosters of 2021.

Our Rankings

Our editorial team tested immunity boosters, read lab reports, contacted manufacturers, and did extensive due diligence to find the best immune system support supplements of 2021. Here are our rankings.

VitaPost Immune Support

image11

VitaPost’s Immune Support provides you with a range of botanical extracts to nourish your immune system. According to VitaPost, the herbal extracts, vitamins, and other ingredients in Immune Support can support a healthy immune system.

The formula contains a blend of modern and traditional ingredients, including beta-glucans, arabinogalactan, quercetin, green tea, vitamin C, vitamin E, and more. Some of the ingredients work by flooding your body with antioxidants to support immunity. Other ingredients work by targeting other aspects of your immune system. With over a dozen proven ingredients in each capsule of VitaPost Immune Support, the formula is one of the best immune support supplements available today. At under $14 per bottle, it’s also one of the best value options on our list.

Mushroom Defense

image8

Mushrooms are surprisingly good for supporting immunity. Studies show mushroom extracts can fight fatigue and protect against cognitive decline. Some studies show mushroom extracts sharpen memory and focus. Others show they improve memory. The makers of Mushroom Defense advertise their supplement as a way to protect you against viral and bacterial threats while also supporting energy and cognition.

Backed by a 67 day refund policy, Mushroom Defense uses ingredients we don’t see in other mushroom supplements, including Agaricus blazei, a rare mushroom extract from a mountain village outside of Sao Paulo, Brazil. Other mushroom extracts in Mushroom Defense include clinically studied mushrooms like lion’s mane, turkey tail, reishi, shiitake, chaga, maitake, and cordyceps sinensis, among others. If you believe in the power of mushroom extracts to support immunity, then Mushroom Defense’s immunity complex may be the best choice.

Price: $59.99

VitaPost Immune Complex

image10

This is the second VitaPost immune Complex supplement on our list. VitaPost’s Immune Complex has many of the same thing we love about Immune Support – including proven ingredients and a competitive price – but it also takes a different approach to supporting immunity. The formula contains echinacea, elderberry, and probiotics, making it unique from Immune Support.

Echinacea, elderberry, and probiotics are three of the most proven immune supporting ingredients in the natural world. Studies show elderberry can reduce the length of cold and flu symptoms. Many people take echinacea for similar reasons. Probiotics, meanwhile, are beneficial bacteria in your intestinal tract that form the foundation of your immune system. Up to 70% of your immune system lies in your gut, and VitaPost Immune Complex supports gut health from the inside out.

Zenith Labs Nano C

image13

Dr. Ryan Shelton of Zenith Labs has created a vitamin C supplement called Nano C Immune Support. You can find vitamin C in virtually every supplement on this list. However, Dr. Shelton has created a special, bioavailable version of vitamin C found in a tincture. You take drops of Nano C daily to support immunity, giving your body a significant dose of vitamin C.

Vitamin C is one of nature’s best antioxidants. With Nano C, you get “nano” versions of vitamin C that are 1,000 times smaller than the vitamin C found in nature. That means your body can absorb it more easily, allowing the vitamin C to quickly and easily enter your bloodstream to fuel your immune cells. Dr. Shelton and Zenith Labs claim Nano C will fortify your body’s immune system, enhance absorption via nanotechnology, promote the production of antibodies, and aid in faster recovery from viruses and bacterial infections, among other benefits.

Price: $49

Epishield Plus

image4

Simple Promise’s Epishield Plus is a dietary supplement that claims to boost your immunity within just two hours of taking it. The supplement uses ingredients similar to others on this list, including vitamin C, vitamin D, and mushroom extract. Epishield Plus also contains an ingredient we don’t see in many other supplements: fermented yeast. The fermented yeast in Epishield Plus can purportedly help you maintain a strong and healthy immune system.

Priced at $50 per bottle, Epishield Plus is frequently out of stock on the Simple Promise website, giving you an indication of how popular the formula is. It’s also one of only two supplements on this list that contains EpiCor, the dried yeast fermentate derived from Saccharomyces cerevisiae. Although you can get vitamin C, vitamin D, and mushroom extracts from many other immune booster supplements, Epishield Plus is unique among its peers for its innovative use of fermented yeast extract.

Price: $49

Advanced Bionutritionals Resistol

image1

Advanced Bionutritionals advertises Resistol as a way to support a healthy immune system. The supplement contains five supporting herbs, including andrographis, eleuthero, Platycodon, prickly chaff flower, and licorice. These five ingredients have been studied for their effects on immunity, and many people take these ingredients daily for their immune support benefits.

Other immune supplements listed here flood your body with vitamin C, vitamin D, and other common vitamins. Advanced Bionutritionals has taken a different approach, using herbs and plant extracts we don’t see in other formulas. If you believe in the power of andrographis, Platycodon, and eleuthero to support immune function, then Resistol may be the right choice for you. And, at under $30 per bottle, it’s affordable compared to competing options on this list.

Price: $29.95

Organixx 7M

image9

Organixx 7M contains mushroom extracts and other ingredients linked to immune function. The formula includes shiitake mushroom extract, reishi mushroom extract, and maitake mushroom extract, three of the most popular and proven mushroom extracts for immunity. These mushroom extracts are packed with beta-glucans that purportedly deliver anti-inflammatory and antioxidant properties.

In addition to these three mushroom extracts, 7M uses cordyceps, lion’s mane, and turkey tail mushroom extracts, three more powerful mushroom extracts known for their ability to support immune function. Organixx recommends taking their supplement daily to support inflammation, healthy digestion, and immune function while protecting against aches and pains.

Price: $55

BioShield MD

image2

All of the best immune support supplements on this list are supported by genuine medical advice. Some are formulated by medical doctors or other immune specialists. With BioShield MD, you get a supplement that can support immunity, natural energy, joint health, mental health, and more. The formula was created by Dr. Mark Rosenberg of Sun Coast Sciences, who has designed it for maximum bioavailability and clinically effective dosages.

We like BioShield MD because it contains some of the best and most proven ingredients for immunity at the right dosages. Instead of flooding your body with dozens of ingredients at low dosages, BioShield MD emphasizes strong doses of tart cherry extract, cocoa extract, curcumin, resveratrol, quercetin, and green tea extract, among others. The ingredients in BioShield MD are rich with antioxidants and flavonoids that can support immune function in multiple ways.

Price: $49.95

VitaPost Turmeric & Ginger

image12

The third and final VitaPost supplement on our list, VitaPost’s Turmeric & Ginger is a premium blend with BioPerine that supports a healthy immune system and joint health by flooding your body with antioxidants. Many people take turmeric and ginger supplements daily to support immunity and overall health and wellness. They’re two of the most popular superfoods in the immunity community. With VitaPost’s Turmeric & Ginger, you can unleash the power of turmeric and ginger.

Each capsule of VitaPost’s Turmeric & Ginger contains 500mg of organic turmeric and 100mg of ginger. There’s also an added 50mg dose of turmeric with 95% curcuminoids and 5mg of black pepper extract to boost absorption. If you’re looking for a no-nonsense turmeric and ginger supplement to support immunity – all at a reasonable price – then VitaPost’s Turmeric & Ginger is one of the best available options.

Price: $23.95

Immuno Defense 4x

image7

JayLab Pro’s Immuno Defense 4x uses just four ingredients to support immunity, including EpiCor, quercetin, bromelain, and vitamin D3. Like other top-ranked options on our list, Immuno Defense 4x has focused on providing strong dosages of a small number of ingredients – not small dosages of a large number of ingredients. You get 500mg of EpiCor and 500mg of quercetin in each serving, along with strong doses of bromelain (150mg) and vitamin D3 (166% DV).

At under $45 per bottle, Immuno Defense 4x isn’t the cheapest immune support supplement on this list, but it’s not the most expensive either. It’s also the second supplement on this list to contain EpiCor, a type of dried yeast extract that has been scientifically studied for its effects on immunity.

Price: $44.95

Doctor G’s Naturals Q-Ion Immune Defense

image3

Doctor G’s Q-Ion Immune Defense is one of the few supplements on this list that claims to be doctor approved, which means at least one medical doctor has approved the use of the supplement for supporting immune function. The makers of Q-Ion Immune Defense claim their formula acts as a powerful anti-inflammatory, allowing you to support antiviral activity and immune health. The supplement also claims to protect you against dangerous pathogens – another claim that few other immune supplements on our list seem to make.

Doctor G’s Naturals is a supplement company created by board-certified physician Dr. John Gordon. Dr. Gordon used his medical expertise to add quercetin, zinc, bromelain, and green tea extract to his Q-Ion Immune Defense formula. The formula also includes something called Ion-Blast Technology, which adds an extra level of bioavailability to the quercetin and zinc within the formula, allowing your body to absorb it faster and easier than normal.

Price: $79.95

Immunity 911

image5

PhytAge Labs claims their Immunity 911 supplement offers the strongest immunity strengthening ingredients, making it ideal for supporting your body’s first line of defense against infection. While its true that Immunity 911 uses a wide range of ingredients (20+ ingredients per capsule), the dosages aren’t as high as competing supplements on this list – despite the big health claims made by PhytAge Labs.

According to PhytAge Labs, the ingredients in Immunity 911 are guaranteed to work. The supplement contains low doses of vitamin C (33% DV) and vitamin E (133%) compared to other supplements on this list. However, it seems to contain strong doses of graviola leaf extract, red raspberry fruit extract, and green tea leaf extract, as these are the first three ingredients in the proprietary formula. Overall, it’s hard to evaluate Immunity 911’s confident health claims, given the lack of label transparency. However, PhytAge Labs is confident their formula works using superfruits, herbs, and mushroom extracts.

Price: $69.95

Immunity Formulas Immune Support

image6

Immunity Formulas Immune Support contains therapeutic-grade herbal essential oils that can purportedly solve all types of immune and virus problems. According to Immunity Formulas, Immune Support will build your natural virus defense, boost your body’s immunity, sanitize all surfaces, and disinfect and purify the air, among other benefits. Just take Immune Support daily to enjoy the power of essential oils.

Crucial essential oils in Immune Support include lemon, oregano, peppermint, turmeric, and cinnamon essential oils. Some studies have shown these essential oils can support immunity in a small way, although other studies have been less enthusiastic. One benefit of Immunity Formulas Immune Support, however, is that it can be diffused throughout the air or applied topically to your skin. If you’d rather breathe in an immune supplement or absorb it through your skin, then the Immunity Formulas Immune Support may be the right choice for you.

Price: $64.99

How We Ranked

Every immune support supplement claims to support immune function. Some contain proven ingredients. Others contain weird herbal extracts backed by few scientific studies. To separate the best and worst immune support supplements, we used the following ranking qualifications:

Scientifically-Proven Ingredients: Zinc, vitamin C, probiotics, vitamin D, and elderberry extract are backed by substantial scientific evidence. Multiple studies have shown these ingredients can support immunity in various ways. We preferred supplements that used scientifically-proven ingredients linked to immunity and immune function.

Effective Dosages: Some immune support supplements use the right ingredients at the wrong dosages. Some supplements contain dozens of ingredients, for example, but none of the doses are powerful enough to impact immunity. We preferred supplements with strong, clinically proven dosages of all listed ingredients.

Honest Health Benefits: Per FDA regulations, supplements cannot claim to cure diseases or improve your health. They can only claim to support health. Many immune booster supplements have even stopped using terms like ‘booster’. Other immune supplements, however, advertise themselves as virtual cure-alls, claiming they can cure diseases, prevent COVID-19, and provide other powerful benefits. These are dishonest, unproven claims. We avoided supplements that made dishonest claims.

Manufacturing Location: We preferred immune support supplements made in registered and certified facilities. Some companies source their supplements from cheap factors overseas. Others use local facilities approved by the FDA and other national regulatory boards. The more transparency we observed during the manufacturing process, the better.

Medical Advisory Board: The best supplement companies have medical advisory boards staffed by medical doctors. This medical advisory board reviews or creates each formula, using their medical expertise to create the best possible immune boosting blend. Some supplement companies do not have a medical advisory board or any professionals on staff, making these formulas less legitimate – and less effective.

Manufacturer Reputation: Some manufacturers have launched immune support supplements to make a quick buck. 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.

Ingredient Sources: Some immunity boosters contain unique ingredients we don’t see in other supplements – like unusual mushroom extracts and other blends. We preferred nutritional supplements that used transparent and reputable ingredient sources.

Price & Value: Some people want to spend $10 on an immune support supplement. Others want to spend $100. We listed a range of immune booster supplements at different price ranges, although we emphasized good value at every price.

Side Effects of Immunity Boosters

When following the recommended dosage instructions on your immune support supplement, you’re unlikely to experience any side effects, assuming you’re a healthy adult who is not taking medications.

By law, nutritional supplement companies must use ingredients and dosages that are Generally Recognized as Safe (GRAS) by the FDA. These ingredients have been found to be safe for humans to take when used at normal dosages. All reputable supplement companies stick to this list.

It’s possible you could experience indigestion, bloating, or mild stomach discomfort after taking an immunity booster for the first time. Some people struggle to process the ingredients in capsules and tablets.

However, it’s important to talk to your doctor before taking any supplement, especially if you have an illness or are taking medications.

Scientific Evidence for Immunity Boosters

Studies show that certain fruits, vitamins, minerals, herbs, and plant extracts can support immune function. By taking these ingredients daily, you could strengthen your body’s natural defense against illness, disease, and aging. Your immune system is crucial for overall health and wellness. That’s why many people take immune booster supplements daily.

One of the best ways to support your immune system is to follow good diet and lifestyle habits. Eating a well-balanced diet, drinking lots of water, getting lots of sleep, and prioritizing exercise can all have positive impacts on immunity. Your body can’t defend itself if you have poor diet or lifestyle habits.

Similarly, other things can weaken your immunity. A poor diet, including a diet with too much sugar, can significantly weaken your immunity. Smoking, excessive alcohol usage, poor sleep habits, dehydration, obesity, stress, and bad exercise habits can also weaken your immune system.

Vitamin C is one of the most popular immune support supplement ingredients. Numerous studies have shown that vitamin C can help your immunity in various ways. That’s why many of the supplements above contain vitamin C. According to the National Institutes of Health, your body needs vitamin C to synthesize collagen, L-carnitine, and certain neurotransmitters. It also plays a vital role in the creation of connective tissue, which impacts wound healing. Vitamin C is also a powerful antioxidant, which means it targets disease-causing free radicals throughout your body. Some studies have even shown that vitamin C prevents or delays the development of certain cancers.

Vitamin D is also important for immunity. Studies show that people who are deficient in vitamin D tend to have much poorer immune function than those who get their recommended daily intake. Vitamin D deficiency is linked with autoimmunity and an increased risk of getting infections, including the flu. Historically, vitamin D was used to treat infections (including tuberculosis) before the invention of antibiotics. You can get vitamin D from food sources. Or, your body can convert vitamin D3 from sunlight into usable vitamin D.

Protein is crucial for immunity. Most of the immune booster supplements above do not contain protein. However, protein is important for the immune system. Protein is made up of amino acids, and your body needs amino acids as fuel for the immune system. The best sources of protein include fish, poultry, beef, pork, eggs, yogurts, nuts, beans, and soy products. Protein plays a particularly important role in supporting immunity within your intestinal cells. 70% of your immune system is found in your gut, and protein can support immunity from the gut to the rest of your body.

Many people take zinc supplements daily for immunity. Zinc is an important mineral that we get from our food. Like vitamin D deficiency, zinc deficiency is associated with poor immune function. Studies show that people with less zinc tend to have a higher risk of developing infectious diseases. Zinc also has antioxidant and anti-inflammatory effects, and even mild zinc deficiency could cause immune dysfunction. If you aren’t getting enough zinc from food sources (like meat, oysters, nuts, or whole grains), then you may want to take a zinc supplement.

Probiotics have been some of the trendiest supplements in the immune support community in recent years. Studies show that 70% to 80% of your immune cells are located in your gut. If you ignore your gut health, then your immune function could suffer. Studies have linked probiotics to immune-related diseases and viral infections. Other studies have even shown that probiotics could help treat and prevent seasonal allergies.

Elderberry isn’t known extensively outside of Europe, but that is rapidly changing. A growing number of people are using elderberry regularly for its medicinal and health benefits. It’s been used for centuries in Europe as a home remedy for cold and flu symptoms. Today, some European doctors even recommend elderberry extract for increasing recovery from colds and flus. Science tells us that elderberry extract is rich with vitamin C, making it a powerful immune booster. In one study, 60 adults took 15mL of elderberry syrup 4 times a day, then experienced an improvement in symptoms 4 days earlier than a placebo group.

Echinacea, like elderberry and other ingredients listed here, has been used for centuries as a medicinal plant. Today, science has validated the use of echinacea as an immune support ingredient. In this study, for example, researchers found that short-term use of echinacea could shorten the duration and severity of upper respiratory infections and colds. Echinacea is effective when taken at the onset of symptoms, but it appears less effective when taken later.

A growing number of immune support supplements contain ginger. Ginger has been used in traditional medicine for centuries for health and wellness. Today, we know ginger works because of its antioxidant and anti-inflammatory properties. Like garlic, ginger also seems to have antibacterial and antiviral properties. All of these properties could make ginger a superfood for supporting immunity.

Turmeric is prized for its antioxidant properties. Many people take turmeric daily for immunity. Turmeric is rich with curcuminoids like curcumin that have been linked to anti-inflammatory properties. However, turmeric’s immune benefits may lie outside of its antioxidant properties. In this study, researchers found that turmeric could support the immune system by activating multiple types of immune cells. Studies also show that turmeric is poorly absorbed by the body unless taken with black pepper extract (often found in supplements as BioPerine), which increases bioavailability by 2,000%.

Ultimately, there’s plenty of evidence linking immune support supplements to scientific benefits. Studies have shown that the best immune support supplement ingredients, including the ingredients listed above, have been linked to immunity in multiple studies.

Q: What are T cells?

A: Some immune boosting supplements specifically claim to target T cells. T cells help to fight infections in two ways. There are ‘helper’ T cells that activate B cells, secreting antibodies and killing infected target cells. There are also ‘killer’ T cells that directly target and destroy infected cells without producing antibodies.

Q: What are antibodies?

A: Elderberry is a folk remedy popular in Europe for supporting immunity. Studies show that elderberry is backed by real scientific evidence. Because elderberry is rich with vitamin C, it appears to reduce the length of cold and flu symptoms. Studies show elderberry could help with cold recovery more than a placebo.

Q: Can turmeric help with immunity?

A: Turmeric is rich with curcuminoids like curcumin that appear to have anti-oxidant effects. Studies show that oxidation is linked to disease and illness. By targeting inflammation, turmeric could help with immunity. Studies show some people experience powerful effects after taking turmeric regularly.

Q: How stress impact my immune system?

A: Studies show that stress weakens your body’s natural defenses. Stress has a significant effect on your immune system. When stressed, your body releases cortisol, adrenaline, and other stress hormones to help your body cope. Cortisol can decrease inflammation in the body. However, chronic stress can increase your risk of health problems by impacting immunity.

Q: Should I expose myself to germs to increase immunity?

A: You need germs to stay healthy. Your immune system can adapt. When your body encounters a foreign substance, it attacks that substance and remembers it. If that substance comes back, your body knows what to do. We’ve seen this with measles: a single measles infection can protect you for life.

Q: Are allergies the sign of immune issues?

A: Allergies are caused by a mistaken immune response. Your body detects something harmless, like pollen or a type of food, as a pathogen. Your body launches an immune response against it, causing you to experience allergy symptoms.

Q: What are autoimmune disorders?

A: When your body detects and attacks itself erroneously, it’s called autoimmunity. Your body is attacking its own tissues, for example, because it believes the tissues are foreign pathogens. Multiple sclerosis, lupus, rheumatoid arthritis, and psoriasis are all common autoimmune disorders.

Q: How do vaccines impact immunity?

A: Vaccines work by stimulating the immune system to produce antibodies against a foreign invader. Instead of infecting you with the disease, they teach your body to defend against the disease. Most vaccines use a unique component of the pathogen. When you’re exposed to the pathogen at a future date, you have minimal to no symptoms.

Q: Does garlic help with immunity?

A: Garlic has an active ingredient called allicin sativum that purportedly has antiviral and antimicrobial effects on the common cold. Some studies have found significant immune support benefits linked to garlic, while others have found no difference between garlic and a placebo. Nevertheless, garlic remains one of the most popular natural remedies for immunity.

Final Word

Immunity booster supplements use vitamins, minerals, and herbal extracts to support immunity in various ways. Studies show that many ingredients, including vitamin C, vitamin D, zinc, and echinacea, could support immunity in a significant way.

By taking the right immune support supplement, you could help your body defend itself against infections by supporting your natural immunity.
