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.

Vitamin C is a water-soluble vitamin most widely known for its role in supporting immune health. It provides potent antioxidant protection, as it helps combat cellular damage from free radicals caused by oxidative stress, thus protecting health overall. Vitamin C also boosts the function of immune cells and is a key nutrient in the synthesis of collagen.
