7 Best Antioxidant Supplement for Immune System 2022

Antioxidants play a crucial role in maintaining good health because they may lessen or prevent the effects of free radicals. Free radical damage has been linked to numerous chronic health issues, including cardiovascular and inflammatory disease, cataract, and cancer. Vitamins C and E, selenium, and carotenoids including beta-carotene, lycopene, lutein, and zeaxanthin are some examples of antioxidants. 

Role of Antioxidants in Immunity

Recent clinical trials have found that antioxidant supplementation can significantly improve certain immune responses. Specifically, supplementation with vitamins C, E, and A or beta-carotene increased the activation of cells involved in tumor immunity in the elderly. Supplementation with the antioxidant vitamins also protected immune responses in individuals exposed to certain environmental sources of free radicals.
 

Do We Need Antioxidant Supplements?

Fruits and vegetables are excellent sources of antioxidants. You can increase your blood levels of antioxidants by consuming a wide variety of foods. However, some people may not be able to get enough nutrients only from their diet which is why they take an antioxidant supplement.

Antioxidant supplements contain nutrients, phytonutrients, or bioactive antioxidants, or substances that neutralize free radicals. But if they are consumed in large doses, it may have the opposite effect.

For instance vitamin A. Vitamin A is important for fetal growth and development, but at high doses, vitamin A supplements can increase the risk of birth defects (Trusted Source, Trusted Source). Therefore, women who might be or are pregnant should not take high doses of vitamin A supplements (Source).

Beta-carotene, the precursor of vitamin A, is not shown to lead to birth defects. But since taking the supplement long-term is associated with cancer, pregnant women should consult with their physician before taking beta-carotene supplements (Trusted Source, Trusted Source).

As for Vitamin C, all the adverse effects, including digestive distress and kidney stones, appear to occur when people take it in mega doses greater than 2,000 mg (Trusted Source).

Best to consult your doctor to decide which antioxidant supplement is suitable for you.

I have been taking this reservatrol now for 2 years. In the past, I used to get the flu at least once a year, had bronchitis every September with horrible throat pain. Since taking this supplement, I have only had minor colds that lasts 1-2 days and my bronchitis in September is all but gone. I haven't had a sore throat in 2 years.... for me... this was a big deal!! 

The only other supplements I take is fish oil and a probiotic. I am truly amazed!! I can only speak for myself, but this supplement has really supported my immune system. I notice when I forget to take it, I start feeling tired and less energetic. It has good natural ingredients, so it doesn't hurt to try. This really works!!

b. Do Free Radicals Have Any Benefits?

Your body is continually producing free radicals. Without antioxidants, free radicals would swiftly do serious harm and ultimately cause death. Free radicals do other crucial jobs, though, that are vital for maintaining health. Your immune system, for instance, uses free radicals to combat diseases. Therefore, our body must maintain a certain balance of free radicals and antioxidants.
