Vitamin C’s role in immune enhancement has been strongly evidenced in supplementation research to increase natural killer cell activity, lymphocyte proliferation and immune balance. Vitamin C is also a potent antioxidant, acting to neutralize free radical damage to cells, including DNA, lipids and proteins. As a free radical neutralizing agent, vitamin C readily donates electrons to unstable molecules and breaks the chain of free radical damage to cells and tissues. Vitamin C is also involved in the synthesis of collagen, carnitine and neurotransmitters. The vitamin is considered essential to humans, and while most mammals are able to synthesize vitamin C, humans cannot. As a result, exposure to smoke, pollution, radiation, heavy metal exposure and high-stress lifestyles all increase the body’s requirement for vitamin C.

Buffered C capsules are balanced with calcium, magnesium and potassium to gently deliver high-concentration vitamin C to reduce the potential of gastrointestinal upset.
