Vitamin C is a water-soluble essential vitamin that your body needs.  It and functions as an antioxidant that supports the immune system by stimulating the formation of antibodies.  It is necessary for the production of collagen, which is the support system for your bones, skin, and gums.  This vitamin plays an important role in the healing of wounds, and after surgery.  It plays a special role in your skin to reduce sun damage, reduce wrinkles, and improve overall skin texture.  Vitamin C also enhances the absorption of iron from plant and supplement forms.  This is important for vegetarians or iron deficiency anemia.

This supplement is commonly called ascorbic acid, L- ascorbic acid, calcium ascorbate, sodium ascorbate, ascorbyl palmitate.  These forms are commonly found in supplements and skincare.

Vitamin C is found in fruits and vegetables.  Note many of higher sources are cooked.  Use caution not to overcook as it will reduce the Vitamin C content.  It is best to microwave or steam these rich foods to reduce loss.

Vitamin C and the common cold and COVID-19

Although vitamin C has long been a popular remedy for the common cold, research shows that for most people, these supplements do not reduce the risk of getting the common cold. However, people who take vitamin C supplements regularly during the cold season might have slightly shorter colds or somewhat milder symptoms when they do have a cold. The recommended dose is 1000mg daily, in 500mg twice a day. Using supplements after cold symptoms start does not appear to be helpful.
