Vitamin C is an essential water-soluble vitamin that is important for optimal health and immunity because it performs numerous roles in our bodies. In addition to its potent antioxidant effects and role as a cofactor in numerous enzyme reactions, vitamin C contributes to our immune defences by supporting various cell functions. Vitamin C is also essential for tissue repair and growth. As the body cannot synthesise vitamin C, we need to get this important vitamin from food and supplements. Vitamin C supplements typically come in powder or capsule form and cater to different preferences around ingestion, taste and texture.
