    How We Ranked the Best Immunity Boosters

    For more information on every brand listed on this post, follow the links to visit the official supplement website:

    Our research and editorial team noticed that every nutritional supplement promises an improved functioning of the body’s immune system. Some brands claim the use of proven effective ingredients, whereas others function on the efficiency of scientifically studied herbal extracts. Our list aims to identify the best and the worse immune support supplements available in the market based on the following aspects:

    Scientifically-Proven Ingredients

    The contents of a supplement are paramount for effective performance. Components like zinc, vitamin C, vitamin D, probiotics, and elderberry extracts are scientifically proven effective in supporting the immune system. We preferred supplements with medically proven ingredients that assist the immune system for enhanced immunity and functioning.

    Honest Health Benefits

    Under regulations stated by FDA (Food and Drug Administration), no supplements can promise to provide remedy over diseases or avail health benefits. Supplements can only claim to support health. It has resulted in some products dropping terms like booster from their names. Some supplement brands still advertise themselves as cure-alls claiming to cure diseases, prevent covid-19 and provide various health benefits. We tried our best to eliminate supplements with false claims and dishonest promises.

    Medical Advisory Board

    A medical advisory board is an integral part of supplement manufacturing companies. The board is responsible for creating and reviewing the formulas that are best suitable for immunity boosting. The best supplement companies ensure the appointment of a medical advisory board to overlook product development with their medical expertise. The absence of medically professional staff makes the supplement formula less legitimate and untrustworthy.

    Manufacturer’s Reputation

    The Covid-19 pandemic has availed many manufacturers with opportunities to sell new immune support supplements to make quick cash. We have chosen the best immunity boosters with an established reputation and offer honest, effective immunity aiding supplements while functioning at high levels of transparency.

    Ingredient Sources

    Various immunity booster ingredients include rare and uncommon components with special medicinal qualities. The companies claim to source some of these ingredients from exotic locations. We preferred nutritional supplements with trustworthy and reputable ingredient sources.

    Price and Value

    Every customer expects an effective supplement within their budget. Best immunity boosters may range from $10 to $100. Our list contains a range of immunity support supplements at different price ranges. We tried to emphasize good value at every price.

    Side Effects of Immunity Boosters

    If consumed as per the prescribed dosage, immunity supplements do not tend to cause any side effects. All the nutritional supplement components have to be Generally Recognised as Safe (GRAS) by the FDA. These ingredients, when taken in normal dosages, are recognized as safe. All well-established supplement manufacturing companies are known to adhere to the list of ingredients.

    Indigestion, bloating, or mild stomach discomfort is possible when consuming the immunity support supplements for the first time. Few users may face issues with any particular ingredient in the product.

    Consulting a doctor before taking any kind of supplements is ideal; it is crucial if you are on any medications or have an illness.

    Scientific Evidence for Immunity Boosters

    Some studies show the benefits of certain fruits, vitamins, minerals, herbs, and plant extracts to support the immune system and its functions. Daily intake of these ingredients can result in a strong and well-developed natural defense against illness, diseases, and anybody ailments. People opt for additional oral supplements to maintain the mannerly functioning of the immune system as it is responsible for the overall health and well-being of the body.

    A well-balanced diet and healthy lifestyle habits go a long way and promote a strong immune system with efficient responses to any antigens or pathogens. Hydration and ample amount of sleep also help in maintaining healthy immune functions. Prioritizing the immune system’s health will help achieve a fitter and healthier body. Carelessness and poor maintenance of the system make you prone to various ailments that can turn into fatal consequences.

    The excessive consumption of alcohol, smoking, stress, bad sleeping schedules, dehydration, obesity, and insufficient exercise can deplete the immune system’s functioning capacities and make you more susceptible to harmful diseases.

    Best Ingredients For Immune Support

    Following are some of the popular ingredients used in oral immune support supplements scientifically proven to aid the system’s functioning:

    Vitamin C

    An essential ingredient found in many immune boosters, vitamin C, has various proven benefits for the human body. It is also popular for its benefits to the immune system. Vitamin C supplements encourage the production of lymphocytes or white blood cells that protect the body against infection. It is responsible for boosting the functional capabilities of the white blood cells by protecting them from any harm or damage caused by the free radicals. The skin defense system needs vitamin C, as it acts as an antioxidant and helps strengthen the skin barriers. The body needs it to synthesize collagen, L-carnitine, and neurotransmitters. Studies show that vitamin C can cut short the healing time of wounds. The deficiency of this vitamin has resulted in poor health outcomes.

    Vitamin D

    Vitamin D has various effects on the immune system cells. The role of vitamin D in the immune system has been acknowledged for 35 years now. Vitamin D plays a crucial role in modulating both the innate and the acquired immunity systems. It is of great importance in autoimmunity. The deficiency of this vitamin can result in various autoimmune diseases. Daily exposure to sunlight is the most efficient and natural way to stock up vitamin D in the system.


    Proteins are the paramount nutrients essential for the functioning of the immune system. They are the backbone of our body’s defense mechanism. Proteins are composed of amino acids responsible for forging immunity. Leukocytes, cytokines, phagocytes are the immune cells that benefit from the presence of protein. The natural sources of proteins are fish, beans, eggs, nuts, poultry, and more. Many immune support supplements overlook the benefits of protein and fail to include it. Protein intake is crucial as it supports immunity throughout the body.


    A majority of people consume zinc supplements. The importance of this mineral is a lot more than we know. Similar to vitamin D, the deficiency of Zinc results in a weak immune system with poor responses. Studies have shown that lower zinc amounts in the body result in potential risks of developing infectious diseases. Zinc is essential for immune cell function and cell signaling. The intake of Zinc supplements stimulates certain immune cells and effectively reduces oxidative stress. A sufficient amount of zinc present in the body promotes immune response in older adults. The natural sources of zinc are meat, oyster, nuts, and whole grains.


    Probiotics are the most popular ingredient found in supplements all over the market. Probiotics are the good bacteria known to maintain a healthy digestive and immune system. Studies suggest that 70% of the immune cells are present in the gut. On the entrance of any foreign invader in the system, the probiotics secrete protective substances to boost the immune functions and prevent the invader’s attack. Probiotics have also been related to aiding immune-related diseases and viral infections. They are also linked to treating and preventing seasonal allergies. Foods loaded with these good bacterias are plain greek yogurt, kefir, and fermented vegetables.


    Elderberries are rapidly gaining popularity all over the world for their numerous medicinal and health benefits. Historically used as a cure for cold and flu, the elderberry extracts are proving more effective in recovery from these diseases. These berries contain a bunch of immune boosters, antioxidants, and vitamins A, B, and C. They serve to keep the immune system strong and powerful to defend against any type of infection.


    Echinacea has been used as a medicinal plant for centuries now. It is validated as an immune support ingredient that shortens the duration and severity of respiratory infections and colds. Echinacea has been deemed more effective when consumed on the onset of symptoms rather than later. Research shows that echinacea is responsible for increasing the number of white blood cells that serve to fight infections.

    Turmeric and Ginger

    Turmeric and ginger supplements are in trend these days. Traditionally used for medicinal purposes, Ginger is gaining recognition for its antioxidants and anti-inflammatory properties. The presence of Gingerol makes Ginger a perfect immunity booster. On the other hand, Turmeric is widely popular for its antioxidant properties. A study suggests that Turmeric supports the immune system by activating multiple immune cells.

Cortisol is responsible for decreasing inflammation in the body. But chronic stress can result in serious damages to the system and lead to chronic ailments.

    Q: Does exposure to germs increase immunity?

    Q: How do vaccines impact immunity?

    A: Vaccines are a precautionary measure. They work by stimulating the body’s immune system to produce antibodies against the invader. The dose from the vaccine works without infecting the body to help the immune system learn defense against the disease. Most vaccines use unique strains of the pathogen. When the body faces an actual pathogen attack, it eliminates the pathogens effortlessly with zero to no symptoms.
