Best Immunity Booster Supplements for Immune System Support

The immune system is your natural defense against anything that will enter and attack your body. If it is healthy, then you are healthy.

There are lucky enough people to have naturally robust immune systems and others that are so poor they need medical information. Most of us fall somewhere in between.

A healthy diet and lifestyle help boost our body’s immunity, and SUPPLEMENTS can be an integral part of this. Considering the amount of international travel and global exposure to illness we are up against today, supporting our natural immunity is more critical than ever.

Unfortunately, hundreds of supplements claim to support immunity. The scientifically PROVEN individual supplements that are best for our immunity are plants, Vitamin C, and zinc. Many immune-boosting supplements on the market do not work as advertised and may not have enough of those ingredients to be considered beneficial.

With this in mind, here is our list of some of the best immunity boosters of 2021.

How We Ranked The Best Immune Supplements

All immunity booster supplements have similar claims and often even similar ingredients. So how do we rank them or decide which are the best immunity boosters for you?

The Science

First, we look at any scientific evidence for the ingredients behind these claims. For example, vitamin C and D, probiotics, Zinc, and elderberry extract have substantial scientific evidence showing benefits to the body and, specifically, the immune system.

It would be ideal to look at studies on the supplements themselves, but because the supplement industry is not FDA regulated in the United States, there is rarely a study to back them up.

Dosage, Dosage, Dosage

Unfortunately, the lack of regulation means a supplement could contain everything it claims to, all the right things, but not be at a dose that is effective in any way. It’s essential to look for supplements with science-backed dosage amounts, valid for any supplement you are looking to take.

No Illegal Lying

One part of the supplement industry that the FDA regulates to prevent extreme and life-altering fraud is the claim to be a cure. It’s important to choose supplements claiming to support good health or different parts of the body, not claim to be the cure-all or prevent-all to diseases and cancers. This is mainly because of COVID. With this new disease, there has been a flood of illegal supplement advertising online claiming to protect you from it or cure you of it- never fall for it.

Manufacturer

Any supplement you consume should be from a known manufacturer with a known location and appropriately certified facilities. Authoritativeness is not just roundabout transparency in business issues; it’s literally about safety. We are often putting these supplements directly into our bodies.

We need to know where they are coming from and follow the appropriate health guidelines when making their products. We always prefer companies with the most transparency possible.

Medical Advisory Board

Want to know if you’re buying from a highly qualified supplement provider? See if they employ a medical advisory board at their company staffed with certified medical doctors and scientists. Preferably, the entire board, but definitely at least the majority of it. It’s no accident that the healthiest, safest, and most likely to work supplement blends have medical professionals involved in their inception.

Reputation

Does the manufacturer even have a good reputation? Some companies pump out many products, and most or all have bad reviews. We looked to see if this was the case with these supplements, and so should you. We prefer a manufacturer with a long and established history, but at least not a bad history, even if that means using a product from a newer company. Using a quality supplement limits the likelihood of being conned by someone in it to make a quick dollar off of you.

Sourcing

It is ideal when a company transparently lists where their ingredients are sourced, mainly if they use a unique element not often seen in other supplements of that nature.

Price vs. Value

Hopefully, we were able to provide you with a range of choices when it comes to cost. We all have different budgets and wanted to keep that in mind. We tried to pick some of the best from each end of the price range to show you can have good value at any price.

The Science Behind the Ingredients

If you don’t particularly care about science, feel free to skip this section, but we encourage everyone to care about what science says about what we are taking to try and be healthier.

Studies support some things making a difference in immune function and being crucial to overall health. Here are the most common or most visible immune support ingredients on this list and what the science says about them:

Vitamin C

Probably the most popular ingredient, numerous studies support the positive effects of Vitamin C. The National Institutes of Health makes it clear we need this vitamin to synthesize L-carnitine, certain neurotransmitters, and collagen. As an antioxidant, it targets disease-causing free radicals throughout the body, with some studies showing it helps prevent or delay cancer growth. Because our regenerative ability must create connective tissue, it also dramatically impacts our natural healing abilities.

Vitamin D

Those deficient in this vital vitamin have a more impaired immune function and many other problems ranging from insomnia to depression to muscle soreness. It’s linked with an increased risk of infection and autoimmunity issues. They even used it to treat infections in the not-so-distant past (before antibiotics) because we could see it had positive effects even then. Vitamin D can also be obtained from sunlight and foods.

Vitamin E

Vitamin E is a nutrient that is naturally available in foods like almonds, wheat germ, spinach, broccoli, etc. Vitamin E boosts the immune systems of all humans, so it is an essential element to add to our diet. It helps to improve cell function and widen blood vessels, so you don’t have blood clotting.

Protein

Protein is crucial for several healthy body functions, not least of which is a healthy immune system. While the above supplements mostly don’t contain protein, it seemed worth noting how vital this is to our readers. You can obtain protein from foods like soy products, foul, eggs, fish, beef, pork, nuts, beans, dark green vegetables, and yogurts. Protein becomes an amino acid in the body which is highly vital for healthy immune function. 70% of the immune system is in the gut, specifically your intestinal cells.

Zinc

Zinc is an antioxidant with anti-inflammatory effects, and studies show people with less than the average healthy adult present a higher risk of developing the infectious disease. Obtained from food, zinc deficiency is also associated with a flawed immune system. Even if you are uninterested in immune-supporting supplements, people not getting enough Zinc through their diets should seriously consider a zinc supplement.

Probiotics

Although a trendy supplement, probiotics are crucial to a healthy gut fauna, and we have already established that 70% of the immune system is in the gut. Probiotics are not just beneficial for the immune system, though. It seems like discovery is made; showing a healthy heart is vital for some healthy functions. Probiotics have been linked to immune-related diseases and viral infections, with some studies showing they can help treat or prevent seasonal allergies.

Elderberry

Elderberry has been used in Europe for centuries as a herbal remedy for the common cold and flu. It has shown to be beneficial for treating fever, which was ideal before creating more potent medications. Some doctors recommend increasing cold and flu recovery (though it should not be relied on when having severe symptoms, including COVID). Science says Elderberry is rich in Vitamin C. One study had 60 adults take 15 mL of elderberry syrup 4x a day, with everyone experiencing improved symptoms up to 4 days earlier over the placebo group.

Echinacea

Much like Elderberry, echinacea has also been used for centuries as a medicinal plant. Science has since validated the positive results in supporting the immune system. One study found short-term use shortened the duration and lessened the severity of upper respiratory infections and colds. It appears to only be effective after the onset of symptoms; otherwise, it’s just a tea ingredient.

Ginger

An ingredient of traditional eastern medicines for centuries, today we know ginger to be a powerful antioxidant and anti-inflammatory. Much like garlic, it also has antibacterial and antiviral properties.

Turmeric

Another antioxidant, turmeric, is rich in curcuminoids which are linked to anti-inflammatory properties. However, this study showed turmeric activating immune cells, which is a wholly different benefit to the immune system than just as an antioxidant. Turmeric is poorly absorbed into the system unless paired with black pepper extract, which increases its bioavailability by 2,000%, which is something to keep in mind if you’re looking to add it to your daily supplement routine.

Best Immunity Booster Supplements-Final Thoughts

Everyone should consider taking supplements to support healthy body functions, including the immune system. All immune systems supporting supplements use similar vitamins, minerals, or plant extracts to help keep you healthy. There are plenty of studies to back up these ingredients, and you should consider adding something to your daily routine, whether through one of these supplements or diet choices.

Hopefully, this list has taught you how to pick out your immunity booster supplements, the basics of what you need, and has encouraged you to give something on this list a try that fits your needs, wants, and budget. In these uncertain times, it’s more important than ever to make sure we take care of ourselves and help our immune system protect us. Try one of the best immunity booster supplements in 2021 today!
