Your immune system is your body’s biggest defense against infection and disease. And keeping this vital system strong is the number one thing you can do to help your body fight off the many threats it encounters every day.
You can do several things to boost your immune system—from eating a healthy diet of nutritious foods and physical activity to getting enough sleep—but sometimes we need extra help. If you’re looking for a way to kickstart your immune cells, you might consider taking an immunity-boosting supplement.
It’s advised to always speak to a healthcare professional before taking dietary supplements.

How We Chose the Best Immunity Boosting Supplements
Quality of Ingredients
High-quality immune boosters begin with high-quality ingredients. We looked for supplements that contained elements backed by science and had a proven track record of boosting immunity.
We also looked for supplements that used natural, organic ingredients whenever possible. We believe that nature knows best and that supplements made with natural ingredients are usually better tolerated by the body than those made with synthetic ingredients.
Potency and Effectiveness
The potency of a supplement is essential because most research demonstrates that it has to be dosed correctly for an ingredient to be effective. This is especially important for immunity-boosting ingredients like vitamin C, which has a very short half-life in the body and needs to be dosed multiple times throughout the day to be effective.
We looked for supplements that contained high doses of scientifically proven immunity-boosting ingredients. We also researched verified product reviews that clarified that the supplements worked for the customers who purchased them.
Quality supplement brands are always happy to be transparent with their testing results. Therefore, we looked for brands that had their products tested by a third-party laboratory to ensure purity and potency.
We also made sure that the brands we chose had products that met all the Good Manufacturing Practices (GMP) requirements laid out by the Food and Drug Administration (FDA). This is a voluntary program, but it’s one that most supplement brands participate in to ensure that their products are of the highest quality.
Finally, we found that the best immunity booster supplements often come from brands with a mission. These companies don’t just say they care about the environment and people. They show it through their policies and actions.
We looked for brands that used sustainable packaging, donated to charity, and had a commitment to social responsibility. We also gave preference to brands that were transparent about their manufacturing processes and had a commitment to excellence.
What Are Dietary Supplements?
Supplements are things you take to improve your health and help you get the essential nutrients that you need. People take supplements for various reasons, including to:
- Boost immune health
- Support the development of healthy immune cells
- Ensure they get essential nutrients and vitamins (e.g., vitamin C, vitamin D)
- Help ward off respiratory tract infections
- Help prevent certain infections
- Help with inflammation (e.g., turmeric)
- Improve sleep
There is a broad range of supplements that offer different benefits. For example, one may target respiratory tract infections, while another may act as vitamin C or vitamin D supplementation. Some are explicitly known for their immune-enhancing properties, while others are known to help with managing stress.
Do Supplements Boost Immunity?
Yes, if you take the right kind. When it comes to immunity, there are two types of supplements: those that may help support immunity and those that make big claims but don’t have any scientific backing.
Some supplements may help support your immune response by providing nutrients essential for immune system function. For example, vitamin C is a well-known immune booster. It’s a water-soluble vitamin found in citrus fruits like oranges and grapefruits. Vitamin C is also available in supplement form.
Other supplements, such as turmeric and garlic, have been traditionally used to help fight off colds and other respiratory infections and reduce symptoms. These supplements are thought to work by stimulating the immune system. Some may even help with wound healing and have antiviral effects.
Keep in mind that there is no scientific evidence that any supplement can prevent or cure any disease, including the common cold or flu. Supplements can only give your immune system the tools to fight off infection and shorten the duration of time that you feel under the weather.
All of the products on this list contain scientifically proven immunity booster supplements that are effective in helping you stay healthy.
Can I Take Immune Boosting Supplements Forever?
Yes, you can take most immunity-boosting supplements indefinitely. However, it’s always best to speak with your doctor before starting any supplement, especially if you have a medical condition or take medications.
Some supplements may interact with medications or have side effects, so it’s best to err on the side of caution. For example, if you take a blood thinner, you should avoid supplements that contain garlic or ginseng, as these can increase the risk of bleeding.
It’s also important to remember that taking supplements is not a substitute for other health measures, such as washing your hands, getting enough sleep, physical activity, and eating a healthy diet. These measures are all essential for maintaining a strong immune defense system.
Finally, keep in mind the importance of not taking more supplements than directed. Some vitamins are fat-soluble, like vitamin E, A, D, and K. This means that they can build up in your body and become toxic if you take too much. As long as you follow the recommended dosage on the product label and don’t “double-dip” with other supplements simultaneously, you should be fine.
Are Immunity Boosting Supplements All Natural?
Most supplements supporting a healthy immune system are all-natural and derived from plants, herbs, and fruits. However, some synthetic supplements on the market may also help support immunity. For example, vitamin C is often synthetic, as it’s challenging to get the required amount from diet alone.
If you’re looking for an all-natural supplement, read the label carefully. It should list all ingredients and indicate whether the product is all-natural.
Most of the products on our list follow a model of only using all-natural ingredients, so you can be sure that you’re getting a product that doesn’t contain any synthetic fillers or ingredients.
What Are the Side Effects of Immune Boosting Supplements?
Most people don’t need to worry about side effects when taking supplements for immune health, as long as they follow the recommended dosage on the product label. However, you may experience side effects, such as:
- Liver toxicity (from too much vitamin A)
- Jitters, anxiety, insomnia (from supplements containing caffeine)
- Upset stomach (if taken on an empty stomach)
It’s always best to speak with your doctor before starting any supplement, especially if you have a medical condition or take medications.
