Product Details

    Vitamin C, or L-ascorbic acid, is a water-soluble vitamin found naturally in citrus fruits and green leafy vegetables. Humans are unable to synthesize Vitamin C endogenously, and since it is water soluble, our body cannot store it longer. Instead, it is regularly consumed either through various foods or dietary supplements.1

    Vitamin C plays a vital role in the biosynthesis of collagen, L-carnitine, protein metabolism, and releasing neurotransmitters 2. L-ascorbic acid is a reducing agent which means it donates a single electron to reacting molecule. Thus, it acts as a powerful antioxidant.3

    An antioxidant is a molecule which reacts with harmful free radicals and protects the human body. Vitamin C is a natural antioxidant and it strengthens the body's immune system from oxidative stress. It also assists in the regeneration of other antioxidants, like Vitamin E or alpha-tocopherol.4 This antioxidant vitamin helps in combating free radicals and neutralizing the effects of nitrites, a harmful chemical preservative found in packaged foods.

    Immune health
    Vitamin C is essential for the production of white blood cells (lymphocytes and phagocytes). Lymphocytes and phagocytes cells protect the body from new invaders.5 Vitamin C protects these cells from harmful free radicals.

    Research studies suggest that consumption of Vitamin C supports your immune system and helps maintain a healthy heart.6 Research studies suggest that consuming more Vitamin C enhances blood antioxidant levels up to 30% and this helps the body to naturally promote a healthy inflammatory response.

    Iron absorption in the body
    Iron is an important nutrient for the body as it supports several physiological functions. Iron is required for making red blood cells and transporting oxygen in cells and tissues. Vitamin C helps in the absorption of elemental iron from various diets. A scientific study demonstrates that consumption of 100 mg of Vitamin C improves the iron absorption by 67%.8

    Enzymatic cofactor
    Vitamin C participates in oxidation-reduction reaction with other biomolecules. This activity is known as redox potential. The mechanism of redox potential helps vitamin C to act as a cofactor in various enzymatic reaction, such as collagen, carnitine, and catecholamine (a chemical compound which acts as a hormone or neurotransmitter) syntheses.9

    Vitamin C is not synthesized in the human body and can be taken externally using supplements. One capsule (one serving) of our Vitamin C provides you with 500 mg of vitamin C to fulfill your daily requirements of Vitamin C.

    Suggested Use: Take 1 capsule daily, or as directed by your qualified healthcare professional.

    Warning: Consult a healthcare professional prior to use if you are pregnant or nursing, taking any medications, or have any medical conditions. Keep out of reach of children. Store in a cool, dry place.
