Your immunity decides how well you are going to live your life and protect yourself against infections. Your immune system works as your body’s natural defense mechanism against dangerous illnesses and diseases.
The sound your immune system is, the healthier you will be. Some people are naturally well-built and have an excellent working immune system. Others focus on exercising regularly and incorporating good lifestyle habits to improve their body’s immune system.
However, many people rely on immunity boosters or immunity supplements to help boost their daily immunity levels. Whether it is a Vitamin C supplement, zinc dosage, herbal, or other plant-based extracts, all these compounds are scientifically proven to help improve your overall immunity score.
As for the products, you can find hundreds of immunity supplements that claim to support your immunity levels. However, only some supplements can live up to the promises that they make. Unfortunately, with most immunity complexes these days, you will only see flashy claims. Most of them do not even function properly, let alone support your body for immunity.
We spent thousands of hours researching, finding, and then compiling the list of Best Immunity Boosters that genuinely support your immunity levels. Keep reading our guide to discover some of the most highly-ranked and best immunity boosters you should consider buying in 2021.

VitaPost Immune Support
VitaPost Immune Support is an immunity-boosting supplement that delivers a range of botanical extracts to help nourish your immune system. According to VitaPost’s website, the herbal extracts, vitamins, and minerals present in the Immune Support supplement can help you develop a healthy immune system.
This immunity formula comprises a mix of both modern and traditional ingredients such as beta-glucans, arabinogalactan, quercetin, green tea extract, Vitamin C, E, among others. Some of the elements equip your body with antioxidants, while others significantly boost your immunity levels. Some other components will target different aspects of your immunity system. Immune Support by VitaPost contains over a dozen scientifically proven ingredients to provide its users with life-altering benefits. This formula is hands down one of the best immunity boosters available in 2021. It comes for under $14 a bottle and is one of the best value providers on our list.
Mushroom Defense is another immunity booster that you should consider purchasing this year. Mushrooms are well-known for supporting your overall immunity levels. According to research studies, mushrooms can actively fight against fatigue and protect you against cognitive decline. As per some studies, mushrooms can even enhance your memory and sharpen your focus. Mushroom Defense’s manufacturers advertise themselves as a way to protect against viral and bacterial infections while also boosting your energy and cognition power.
Mushroom Defense comes with a 67-day refund policy. The supplement uses ingredients that we do not see other immunity formulas using, like Agaricus blazei, a sparse mushroom extract from a mountain village outside Sao Paulo, Brazil. Besides this ingredient, the formula contains other clinically studied mushroom extracts like turkey tail, reishi, lion’s mane, shiitake, chaga, maitake, and cordyceps. If you are someone who abides by mushroom extracts to help support your immunity levels, then Mushroom Defense’s immunity complex may be the perfect choice for you.
VitaPost Immune Complex
This supplement is the second immunity formula produced by VitaPost. VitaPost Immune Complex shares many of its features with the Immune Support supplement by the same brand. One of the most resembling factors in these supplements is the presence of proven ingredients and competitive pricing. This formula is uniquely built compared to the Immune Support formula in that it contains echinacea, elderberry, and probiotics, distinguishing it from other immunity supplements by VitaPost.
Echinacea, Probiotics, and Elderberry are three of the most scientifically backed immune support ingredients from a herbal and natural perspective. According to various studies, using elderberries can help you combat the symptoms of flu and the common cold. Many people consume echinacea for similar reasons. In contrast, probiotics are the beneficial bacteria present in your intestinal tract and act as a strong foothold for your entire immune system. Approximately seventy% of your immune system is present in your gut, and you will notice a holistic development of your gut health from the inside out if you start taking VitaPost Immune Complex today.
Zenith Labs Nano C
Dr. Ryan Shelton from Zenith Labs developed a Vitamin C formula called Nano C Immune Support. You can experience the goodness of Vitamin C in all of the supplements mentioned on this list. However, Dr. Shelton’s formula differentiates itself because it is a unique, bioavailable version of Vitamin C in the form of a tincture that we do not commonly see in other supplements. The company recommends taking drops of Nano C formula daily to help support your immunity by providing your body with a massive dosage of Vitamin C.
Vitamin C is one of the best antioxidants available in our natural environment. When consuming a formula like Nano C, you get “nano” versions of Vitamin C injected into your body which are about 1000 times tinier than the natural Vitamin C. This makes your body absorb these little segments of Vitamin C faster to power your immunity. According to Dr. Shelton and Zenith Labs, Nano C can strengthen your body’s immune system and speed up the absorption process using nanotechnology while promoting the antibodies’ production and supporting fast recovery from infections and viral diseases.
Simple Promise manufactures its Immunity Supplement called Epishield Plus, which is a dietary supplement. This formula claims to boost your immunity levels within two hours of consuming it. This supplement contains ingredients similar to other Immunity Boosters mentioned on our list, like Vitamin C and D alongside mushroom extracts. Epishield Plus also has an unusual ingredient that we don’t often see with other formulas: fermented yeast. This fermented yeast present in Simple Promise’s solution can purportedly help you maintain a strong and healthy immune system.
This formula costs around $50 for a bottle and often runs out of stock on Simple Promise’s website, accounting for its popularity among users. It is also one of the two immunity boosters on our list containing EpiCor, a dried yeast fermentate extracted from Saccharomyces cerevisiae. While you can provide your body with Vitamin C, E, and mushroom extracts from any supplement mentioned on our list, Epishield Plus is a popular and unique choice in the industry due to its innovative usage of fermented yeast extract.
Advanced Bionutritionals Resistol
Advanced Bionutritionals advertises its supplement- Resistol, as a nutritious supplement that can help support your immunity healthily. This supplement uses five supporting herbs: Andrographis, eleuthero, Platycodon, prickly chaff flower, and licorice. These five nutritional ingredients are studied extensively for their beneficial effects on immunity. A vast majority of people consume these ingredients daily to boost their overall immunity.
Most immunity supplements mentioned here will fill your body with Vitamin C, E, and mushroom extracts. Advanced Bionutritionals has taken a different route by including ingredients in its supplements that we do not see other brands using. If you believe in the power-packed benefits of Andrographis, eleuthero, and Platycodon, then Resistol may be the right supplement choice for you. Additionally, this immunity booster will only cost you under $30, thereby making it easier on your pockets.
Organixx 7M uses mushroom extracts and other beneficial ingredients to help boost your immune function. This formula contains mushroom extracts such as shiitake, reishi, and maitake: three of the most popular and proven immune support mushroom extracts. These mushroom extracts come blended with beta-glucans that provide antioxidant and anti-inflammatory benefits reportedly.
Apart from these three mushroom extracts, Organixx 7M also uses cordyceps, lion’s mane, and turkey tail mushroom extracts. Much similar to other nutrients, these three ingredients are also associated with boosting immunity. According to the official website of Organixx 7M, the company recommends consuming their formula daily to promote your immune function, healthy digestion, and support anti-inflammation, all while protecting you from dangerous illnesses and diseases.
Some of the best and highly-ranked immunity boosters on this list come backed with proven medical advice, and few of them are thought of by immune specialists or medical doctors themselves.
With BioShield MD, you can give yourself a supplement that will boost your immunity levels, support natural stamina, mental and physical health, among other benefits. Dr. Mark Rosenberg of Sun Coast Sciences came up with this formula and developed it to ensure maximum bioavailability with clinically effective dosage options for people.
We have chosen BioShield MD for the right reasons: the most influential is its delivery of the best and proven ingredients at effective dosages. It does not flood your body with dozens of effective ingredients at low dosages. Bioshield MD uses substantial dosages of tart cherry extract, cocoa extract, curcumin, resveratrol, quercetin, and green tea extract, among other similar ingredients. The ingredients present in Bioshield MD are rich in antioxidants and flavonoids that are known to support your immunity in numerous ways.
VitaPost Turmeric and Ginger
VitaPost’s Turmeric and Ginger is the third and final immunity supplement on our list by VitaPost. This formula is a premium mix of BioPerine with other healthy ingredients that promote a healthy immune system and joint health by providing your body with a high dosage of antioxidants. Many people consume ginger and turmeric as supplements daily to help support their overall health and well-being. Both of these ingredients are two of the most popular superfoods in the Immunity Industry. You can unleash the full power of turmeric and ginger and use them to your body’s advantage by consuming VitaPost Turmeric and Ginger formula.
Every capsule of the VitaPost Turmeric and Ginger blend comes packaged with 500 mg of organic turmeric and about 100 mg of ginger. There is also an additional 50 mg of turmeric present with ninety-five% of curcuminoids and 5 mg of black pepper extract to help boost your absorption process. If you want to support your immunity levels with a no-nonsense supplement brand, then VitaPost Turmeric and Ginger should be your go-to choice. Additionally, you can purchase this supplement at a very reasonable price. It is no doubt that VitaPost Turmeric and Ginger tincture is one of the best immunity boosters available on our list.
Immuno Defense 4x
Immuno Defense 4x is another nutritious immunity supplement manufactured by JayLab Pro. This natural supplement uses only four ingredients to support your immune system: EpiCor, Quercetin, bromelain, and Vitamin D3. Similar to other well-ranked immunity boosters on our list, Immuno Defense 4x focuses on providing robust dosage options using fewer ingredients than offering low dosage options utilizing an array of components. With every serving of Immuno Defense 4x, you will get 500 mg of EpiCor and 500 mg of quercetin, each alongside robust dosage options of bromelain (about 150 mg) and Vitamin D3 (about 166% DV).
This supplement will cost you under $45 for a bottle, and it isn’t the cheapest option available on our list of best immunity boosters. However, it is not the most pricey either. Immuno Defense 4x is also the second supplement on our list that contains EpiCor; this is a type of dried yeast extract studied scientifically for its impact on immunity.
Doctor G’s Q-Ion Immune Defense
Doctor G’s Q-Ion Immune Defense is one of the few immunity boosters on our list that claims to be medically backed by doctors; this means at least one practicing doctor has approved its usage for better immune function. The creators of the Q-Ion Immune Defense formula claim that their supplement acts as a potent anti-inflammatory supplement. This property allows the formula to help support your overall immune health and antiviral activities. This immunity supplement has also claimed to protect you against harmful pathogens, another claim that only a few immunity supplements have made.
Dr. John Gordon established the supplements company called Doctor G’s Naturals. Dr. Gordon employed his medical expertise to add quercetin, green tea extract, zinc, and bromelain to his Q-Ion Immune Defense formula. This tincture also comes blended with Ion-Blast Technology, adding an extra layer of bioavailability to quercetin and zinc present within the solution; this allows your body to absorb the complex nutrients faster than you usually would.
Immunity 911 is an Immunity enhancement supplement that PhytAge Labs developed. This supplement comes power-packed with some of the most potent ingredients that strengthen your immunity levels. This factor makes it a top choice for anyone looking to support their body’s defense mechanism against infections. PhytAge’s Immunity 911 uses several ingredients, with more than 20 ingredients per capsule. Still, the dosage options aren’t as high as the competing supplements on this list, despite the numerous health claims that PhytAge Labs makes.
According to the website of PhytAge Labs, the ingredients present in Immunity 911 will work guaranteed. This formula contains low doses of Vitamin C (about 33% DV) and Vitamin E (about 133%) compared to its counterparts on our list. Still, Immunity 911 contains substantial dosages of Graviola leaf extract, red raspberry fruit extract, and green tea leaf extract, among other nutritious ingredients. On the whole, it isn’t straightforward to evaluate the huge claims made by Immunity 911 as there is no transparency in its label. However, PhytAge Labs is confident that their immunity formula works incredibly, given the blend of superfruits, herbs, and mushroom extracts.
Immunity Formulas Immune Support
Immunity Formulas Immune Support claims to contain therapeutic-level herbal essential oils that can professedly cure all types of immunity and viral problems. According to the website of Immunity Formulas, Immune Support helps build your natural defense while boosting your body’s overall immunity. It also sanitizes the surfaces, disinfects, and purifies the air alongside providing other benefits. As recommended by the company, consume Immune Support solution daily for heightened effects and immerse yourself in the goodness of essential oils.
Some of the most vital essential oils that Immune Support contains are lemon, oregano, peppermint, turmeric, and cinnamon oils. As per information retrieved from some research studies, these essential oils can help support your immunity levels in small ways. One of the significant advantages of using the Immunity Formulas Immune Support supplement is that it can be diffused within the air or applied topically onto your skin. Suppose instead of consuming, you prefer breathing or absorbing the goodness of an immunity supplement through your skin. In that case, the Immune Support by Immunity Formulas may be the perfect choice for you.
How We Ranked the Best Immunity Boosters
Every immune support supplement available in the market today claims to support a healthy immune function within your body. However, only some of these supplements contain proven ingredients. Others are just a mixture of weird herbal extracts supporting themselves with a few scientific studies. However, to prepare this list of best immunity boosters for you, we used the following ranking metrics to help separate our team from the worst and the best immunity support supplements. These factors are as follows:
For immunity boosting, certain ingredients come with a piece of scientific evidence to help deliver life-altering benefits for your immune system. For example, zinc, probiotics, Vitamin C, D, and elderberry extract are known to improve your immune health substantially. There are several research studies conducted that depict the impact of these ingredients on immunity in a positive light. For this list, we preferred supplements that came with a scientifically proven ingredient list known to benefit your immune system.
Effective Dosage Options
Some Immunity support supplements use the right ingredients but offer the wrong dosage options to their customers. In contrast, some immunity boosters contain numerous ingredients, sometimes even more than a dozen, but offer such few dosage options that their overall impact on your body’s immune system is not evident. While preparing this list for the best immunity boosters of 2021 and comparing different products, we preferred immunity support supplements that offered robust and clinically proven dosage options of all ingredients mentioned on their labels.
Honest Advertised Health Benefits
According to FDA regulations, supplement companies cannot claim that their product or formula can help cure certain diseases to help improve your overall health. That is against their norms. The supplement companies can only claim so much: that their product can help support your health in a particular way. It comes as a surprise that many immunity boosters have even stopped using the term “boosters.”
Still, there are some immunity support supplements in the market today that blatantly claim to be your one-all, cure-all solution. They advertise themselves as the virtual go-to-options, going all the way in to claim that they can prevent certain diseases, even Covid-19, and provide powerful benefits. However, as your guides, we want to inform and lead you. We want to help you in making the right decision. As a customer, even though it gets tempting, we want you to know that such supplement companies are only making hollow claims to lure people into buying their products. But as a responsible buyer, you must know, understand, and analyze if a particular immunity booster is fit for your individual needs or not. We suggest you do not fall for these unproven and dishonest claims, which is why we took the load off your shoulders and did the work for you. We did not choose immunity supplement companies that made false claims to their customers, so you can rest assured that the supplements mentioned here are genuinely the best immunity boosters that you should consider buying this year.
While making this list, we understood the importance of having a certified manufacturing location. For this list, we preferred supplement companies that manufactured their formulas in registered and certified facilities. It is not uncommon to see that some supplement companies often outsource their products from cheap facilities located overseas. Other companies rely upon local factories approved by the FDA and other national advisory and regulatory boards.
The more transparency and honesty we observed in the manufacturing process, the higher we ranked that supplement company on our list. Some companies make fraudulent claims. However, we did thorough research to avoid misleading our readers and protect you from such illegal manufacturers. So, we only made it a point to include legitimate, certified, and approved manufacturing locations over those that misled people.
Medical Advisory Board
Some of the best immunity support supplement companies have a medical advisory board of their own. These companies have their practicing doctors and medical professionals that overlook every aspect and function of their production process. This medical advisory board either reviews or creates formulas by using their medical experience to produce the best quality immunity supplement in the market.
It is also amusing that some supplement companies operate without medical staff or a medical advisory board. It is these companies that you have to look out for and avoid generously. Without a professional doctor or medical staff, these companies’ supplements are illegitimate and without any solid backing to support their benefits. This factor makes these formulas less compelling and less legitimate. However, it would help if you did not worry, as we have only compiled the list of best immunity support formulas for you. For this list, we did not choose supplement companies that operated and produced their products without the help and guidance of a medical professional. Instead, we only included immunity boosters that medical experts led, backed, and developed under the holistic guidance of a medical advisory board.
Like other supplement industries, some manufacturers have only entered the immunity market to make a quick buck without caring about making a difference in people’s lives. We have seen more of this happening, especially during the Covid-19 pandemic. However, another level of trust comes with long-established manufacturers who have been working in the immunity industry for years. They are known for their high-quality immunity supplements, and they carry a long-standing well-rounded reputation, not just for the products they have created but also for the trust they have earned among the customers. However, for this specific list, we preferred immunity supplements produced by manufacturers with a long and well-established reputation for providing honest, high-value, and effective immunity boosters over the years, all while maintaining high-grade transparency among the users.
Some immunity boosters use unique ingredients that we do not see with other supplement companies. For example, some immunity supplements will use a mix of unusual mushroom extracts, while others may go for the routine Vitamin C, E, and zinc blend. Most of these ingredient sources are shady and not actual. Most producers do not purchase and use the best-quality ingredients that are available in the market. These kinds of manufacturers are also very vague about the origins of their ingredients. We suggest that if you do not know a product’s origins, it is better to look for more transparent options. We have done the work for you. This list for the best immunity boosters of 2021 only comprises supplements that we thought were honest with their ingredient’s origins. For this list, we only preferred supplement companies that were straightforward, honest, and transparent in disclosing their ingredients’ source locations to us, and you can trust us with this list.
Price and Value
Some people are comfortable spending $10 for an immune support supplement. Others want to spend more and go up to $100 or more to purchase the same immunity formula. We know and very well understand that different individuals assess value differently. Some associate it with price, while others relate it to quality. We tried to incorporate both ends of the spectrum by understanding that different people will have different needs and preferences. No two customers are alike. So, for this specific list of best immunity boosters, while we incorporate immunity support supplements at different price ranges, we laid a great emphasis on the value that the product offered at every price range.
What Are Some Side-effects of Immunity Boosters?
It is essential to keep in mind that every time you are following a recommended dosage instruction (either by your doctor or the immunity supplement company), you are least likely to experience any side effects of immunity boosters. This conclusion comes with a pre assumption that you are a healthy adult who is not currently under any prescribed medication.
Legally, nutritional supplement companies often need to use ingredients and dosage options that are Generally Recognised as Safe (GRAS) by the FDA. When it comes to the most common ingredients used in immunity boosters, all of them are safe for human consumption under regular dosages. All of the reputable immunity supplement companies abide by this list and follow their guidelines and instructions devotedly.
However, you may still experience a little discomfort if you have never consumed an immunity booster before, just like it happens with any new thing that you try. You may experience indigestion, bloating, nausea, or mild stomach discomfort after popping a pill of an immunity booster for the first time. It is not unusual to watch people struggle to process the supplement in a powdered, capsulated, or tableted form.
Still, just like with any other health supplement, we always recommend that you speak with your doctor first before jumping onto a decision about consuming an immunity support supplement, especially if you have never taken one before. We advise you to always take guidance from your doctor, especially if you are undergoing any treatment or on some prescribed medication. It is for your benefit so that you do not end up making changes your body cannot afford to experience yet.
FAQs About Immunity Support Supplements
Q) How does immunity work in a person’s body?
A) A healthy body is healthy because it contains a well-functional immune system which is the body’s defense mechanism to keep harmful substances at bay. Your immune response has multiple layers to it. It is not a simple concept to understand. The first layer creates a line of defense for your body against pathogens and protects you from cough, cold, reflex, or tears. The primary way in which immunity works is to ensure that no harmful substances enter the territory of your body. A healthy immune system will fight and remove foreign invaders from your body in an effective manner.
Q) What do you mean by T Cells?
A) Some immunity support supplements available in the market today claim to target T Cells in your body specifically. The T Cells in your body fight infections in two significant ways. There are helper ‘T’ Cells that further activate the B cells to secrete antibodies and kill all the infected target cells. The other type of T cells are known as Killer ‘T’ Cells, and they directly target and kill the infected cells without producing any antibodies.
Q) What do you mean by antibodies?
A) Antibodies are protein substances developed by your body’s immune system to fight infections within. Antibodies are a crucial part of the immune system. Your body always requires antibodies to fight various diseases.
Q) What are the best vitamins available in the market today to boost your immunity?
A) Some of the best vitamins available in the market today to boost your overall immunity levels are Vitamin C, Vitamin E, and Vitamin D. These are some of the most popular vitamins that people purchase to support their immune health. According to several research studies, all of these three ingredients can affect your immunity positively.
Q) What do you mean by innate immunity?
A) Innate immunity is your body’s first line of defense mechanism against pathogens or foreign invaders that try to enter your body. Some parts of innate immunity include your skin (which prevents most of the pathogens from entering your body), mucus (that is known to trap pathogens), and stomach acid (that destroys all pathogens). The enzymes present in your sweat and tears also have antibacterial properties, so we hope you take it positively the next time you sweat or cry. There are some immunity support supplements available in the market today that specifically claim to target and boost your innate immunity.
Q) What do you mean by adaptive or acquired immunity?
A) Adaptive or acquired immunity is the part of your body’s immune system that has learned to identify a pathogen. For example, your spleen, thymus, bone marrow, and lymph nodes all regulate this part of your immune system. Whenever these cells or organs perceive a pathogen threat near them, they create antibodies in response to that pathogen threat and therefore protect your body. A person’s adaptive or acquired immunity is as important as their innate immunity. Both of these immunities play a pivotal role in protecting your body against harmful bacteria, infections, and diseases.
Q) What are the best foods that one should eat to boost their immunity levels?
A) Some of the best food options you can consider and consume to boost your overall immunity levels are berries, dark chocolate, red grapes, leafy greens, turmeric, elderberry, and ginger. These foods mentioned here support your immunity in numerous ways, so you should include them in your diet when looking to boost your immunity levels.
Q) What are the worst foods that you should avoid to help support your overall immune health?
A) Some of the worst foods that you should avoid eating to help support your overall immune health are: foods with added sugars, junk, and fast food, foods that contain artificial trans fats, refined carbs (which include white bread, pasta, pastries, cookies, and cakes) alongside processed meat. According to several research studies, you should always avoid the above foods to support your long-term immune health.
Q) Do I need to lose weight to support my immunity levels?
A) There is no guidebook and no hard and fast rule when it comes to protecting your immune system. There’s a rule of thumb that we always follow and advise our readers to. And that is to prioritize your health. Always, always prioritize your health. It doesn’t matter if it’s right or wrong as long as you do something to take care of your health, lifestyle, and diet. Because once you start to take care of your health and prioritize yourself, you will feel strengthened from within, and all of these factors significantly boost your long-term immune health. So, there is no rule that you have to lose weight. However, studies depict that people in a healthy weight range tend to have more robust immunity levels and immune systems. So long as the process makes you feel good, empowered, and strengthened from within, it would be best if you made a choice that speaks to you directly. If you feel like losing weight, then go for it. But if you feel like you are well off without doing that and can still maintain healthy levels of immunity without losing an inch, then why not? After all, it is a personal choice more than a preset rule.
Q) What are some of the best ways through which I can strengthen my immune system?
A) As mentioned before, there is no comparison between a healthy lifestyle and a healthy, nutrient-rich, and fulfilling diet. One of the critical ways to fortify your immune system from within is to adopt a healthy lifestyle and solid dietary habits that support your immunity.
