While it is important to get most of the micronutrients your body needs to support your immune system from wholesome food, vitamin supplements can offer added nutritional support

A large body of research affirms that you can strengthen your immune system with an adequate supply of vitamins. As such, combining these nutrients from standalone products can help address any potential nutritional shortfalls in your diet and provide added support to help boost your immunity this winter cold and flu season.

The A B C D and E of immunity

Vitamin A1 protects epithelium and mucus integrity in the body, which serve as our primary physical barriers against possible infection. This micronutrient is also vital for developing immune system strength and function as it regulates immune cell and antibody responses. In addition, vitamin A works synergistically with vitamin D across specific immune functions.

Your body requires adequate amounts of all eight B vitamins2 to produce various cells involved in the immune response. Two B vitamins (B6 and B12) are particularly important as they are involved in numerous biochemical reactions related to optimal immune function.

Certain immune cells require vitamin C to function optimally and for protection against free radical damage. As such, this vitamin is highly concentrated in immune cells and is consumed quickly during an infection. However, your the body cannot produce vitamin C, which means we need to supply sufficient amounts from our diet and from supplements. A study3 also showed that vitamin C can reduce the duration of a cold (an 8% reduction for adults and 14% reduction for children).

Vitamin D functions as an immune system modulator4 to regulate its response and various functions. Specifically, vitamin D reduces levels of inflammatory proteins called cytokines and helps to increase levels of antimicrobial proteins such as B lymphocytes and killer T cells that destroy invading germs and viruses. Vitamin D supplements can help to compensate for a lack of exposure to sunlight during winter as we cover up or spend more time indoors.

Vitamin E5 boosts immune cell production, including the B-cells that produce antibodies to fight bacteria. Vitamin E also acts as an antioxidant, protecting immune cell membranes from damage by free radicals, and produces proteins and other key mediators in the immune response.

Biogen’s Vitamin E contains D-Alpha Tocopheryl, a natural and bioavailable form of this antioxidant vitamin.
