Best Immunity Boosters – Top Immune System Supplements That Work

“Your body’s immune system protects you from illness, disease, and infection”

Good health depends on a strong immune system. While some people naturally have a strong immune system, others follow a healthy lifestyle and eat foods that boost their natural immunity. On the contrary, many people seem to have low immune function due to various reasons. There could be a variety of reasons for this, such as poor eating habits, medical problems, and unhealthy lifestyles.

Today, many people take immune booster supplements to support their natural immunity.

Hundreds of immune system supplements claim to boost immunity, so choosing the best one becomes daunting. We have spent hours researching the best immunity boosters of 2021 to find the ones that actually work and are popular.

    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, vitamin E, probiotics, green tea, 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 components, 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 false 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 medical knowledge, 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 different 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 prices, although we emphasized good value at every cost.

    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 are safe for humans to take when used at regular 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 essential to talk to your doctor before taking any supplement, especially if you have an illness or are taking medications.

    Scientific Evidence for Immunity Boosters

    Your immune system is crucial for overall health and wellness. 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. 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 positively impact 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 weaken your immune system.

    Vitamin C is one of the most prevalent 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 creating 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 essential for immunity. Studies show that people 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 diseases (including tuberculosis) before 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 essential 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 protein sources include fish, poultry, beef, pork, eggs, yogurts, nuts, beans, and soy products. Protein plays a vital role in supporting immunity within your intestinal cells.

    Zinc is an essential mineral that we get from our food. Many people take zinc supplements daily for immunity. 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 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 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 flu. Science tells us that elderberry extract is rich in vitamin C, making it a powerful immune booster. In one study, 60 adults took 15mL of elderberry syrup four times a day, then experienced an improvement in symptoms four days earlier than a placebo group.

    Like elderberry and other ingredients listed here, Echinacea has been used for centuries as a medicinal plant. Today, science has validated the use of echinacea as an immune support ingredient. For example, in this study, 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 in curcuminoids like curcumin 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 those listed above, have been linked to immunity in multiple studies.

    FAQs About Immunity Boosters

    Q: How does immunity work?

    A: A healthy body has an immune system that keeps out harmful materials. Your immune response has multiple layers. The first layers are like a cough reflex or tears, creating the first line of defense for your body against pathogens. A healthy immune system attacks and removes foreign invaders from your body efficiently.

    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: Antibodies are proteins made by the immune system to fight infections. Antibodies are a crucial part of an immune system. Your body needs antibodies to fight disease.

    Q: What are the best vitamins for immunity?

    A: Vitamin C, vitamin E, and vitamin D are some of the most popular vitamins for immunity. All three have been linked to immune function in numerous studies.

    Q: What is innate immunity?

    A: Innate immunity is your body’s first line of defense against pathogens (foreign invaders) that try to enter your body. Parts of innate immunity include your skin (which prevents most pathogens from entering your body), mucus (that traps pathogens), and stomach acid (that destroys pathogens). Enzymes in your sweat and tears also have antibacterial properties. Some nutritional supplements specifically claim to target innate immunity.

    Q: What is adaptive or acquired immunity?

    A: Adaptive or acquired immunity is the part of your immune system that has learned to recognize a pathogen. Your spleen, thymus, bone marrow, and lymph nodes regulate this part of your immune system. These cells and organs create antibodies in response to a pathogen threat.

    Q: What are the best foods for immunity?

    A: Berries, dark chocolate, red grapes, leafy greens, turmeric, elderberry, and ginger are some of the best foods for immunity.

    Q: What are the worst foods for immunity?

    A: Studies show that the worst foods for immunity are foods with added sugars, junk food, fast food, foods with artificial trans fats, refined carbs (including white bread, pasta, pastries, cookies, and cakes), and processed meat.

    Q: Should I lose weight to help immunity?

    A: Studies show that people with a healthy weight tend to have more robust immune systems than overweight people.

    Q: What are the best ways to strengthen my immune system?

    A: The best way to strengthen your immune system is to adopt a healthy lifestyle and dietary habits. Eating a balanced diet and regularly exercising are effective ways to improve your immune system.

    Q: What habits hurt my immune system?

    A: Smoking, poor diet and exercise habits, excessive alcohol consumption, stress, poor sleep habits, and other unhealthy habits can all weaken your immunity.

    Q: How is gut health linked to immunity?

    A: 70% to 80% of all cells in your immune system are found within your gut. Your gut plays a crucial role in immunity. Many people take probiotics and other gut health supplements to support immunity.

    Q: How does age impact immunity?

    A: As you get older, your immune function tends to decrease. Older people tend to have worse immune function than younger people. However, diet, exercise, and lifestyle habits can also play a significant role in immunity, regardless of age.

    Q: Can immune supplements improve immunity?

    A:Most supplements can support immunity, even if they don’t specifically claim to improve immunity. Per FDA regulations, supplements cannot claim to improve immunity, cure disease, or improve your health.

    Q: Is exercise good or bad for immunity?

    A: Moderate exercise is good for immunity. Additionally, healthy people tend to have better immune function. However, frequent, strenuous exercise can reduce immunity if you are not letting your body recover.

    Q: How does vitamin C help immunity?

    A: Vitamin C is an antioxidant, which means it neutralizes free radicals throughout your body. Free radicals are linked to diseases and illnesses. Studies show that vitamin C doesn’t prevent colds or respiratory conditions, but it could shorten the duration of the diseases.

    Q: How does vitamin D help immunity?

    A: Vitamin D appears to impact multiple aspects of your immune system, supporting immunity in various ways. People deficient in vitamin D tend to have poorer immune function than people who get their daily recommended dose of vitamin D.

    Q: Does echinacea help with immunity?

    A: Echinacea has been popular for centuries for its effects on immunity. Some studies have shown that echinacea is effective when taken at the onset of cold and flu symptoms, although other studies have been less conclusive.

    Q: How does zinc help immunity?

    A: Zinc is crucial for immunity, and studies show that taking zinc can shorten the duration of colds when taken at the onset of symptoms.

    Q: How do probiotics help immunity?

    A: Studies show that probiotics could support gut health. Your gut is home to 70% to 80% of your immune cells, so supporting gut health can help with immunity. One study found that probiotics can reduce the length of respiratory infections.

    Q: Can elderberry help with immunity?

    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 in 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 in curcuminoids like curcumin that appear to have antioxidant 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 does 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, like 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 tissues, for example, because it believes the tissues are foreign pathogens. Multiple sclerosis, lupus, rheumatoid arthritis, and psoriasis are 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 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.

    The best immune support supplements on this list are supported by sound medical advice.

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