The vitamin C I like to use is the Ester C 1000mg + Bioflavonoids vitamin C. Vitamin C is one of the most vital vitamins to protects various cells within the body and improve overall health. According to WedMD, vitamin c can also act as a shield against heart disease, prenatal health complications, skin wrinkling and eye disease. This vitamin can be found in various fruits (mainly citrus fruit), but also in vegetables and other foods. One of its major roles is to produce a protein known as collagen which is imperative for healing cuts and other injuries. Vitamin C supports immune health to fight off viruses and other temporary illnesses and thus being the reason why it is advised to consume vitamin c dietary supplements during flu and cold seasons.
