Calcium Ascorbate (Buffered Vitamin C) Benefits and Uses


Vitamin C is a water-soluble and mineral salt that is required by humans for a variety of biological processes. Vitamin C is non-endogenous so it cannot be synthesized by the body and therefore must be obtained through consumption of external sources like fruits and vegetables or dietary supplements.


Individuals with poor absorption or low consumption of dietary fiber often take Vitamin C supplements as it is a potent antioxidant and is essential for collagen synthesis, a protein implicated in the development of tissues, bones, and muscles and the maintenance of skin elasticity. It is also involved in the biosynthesis of neurotransmitters and carnitine.


Anecdotal evidence suggests that supplementing with Calcium Ascorbate may help increase Vitamin C levels without the possible gastric irritation caused by the acidity of ascorbic acid. As a potent antioxidant, Calcium Ascorbate (Vitamin C) may also improve immune function, induce detoxification, and act as an anti-aging compound.
