The human body requires a number of vitamins and minerals to function optimally, and vitamin C is one of the most important. A water-soluble vitamin, vitamin C helps with the formation of collagen, an essential component in the health of your skin, joints and blood vessels. It also supports the production of norepinephrine and vasopressin, two chemicals that help regulate your blood pressure. Plus, it helps promote energy production, supports the immune system and helps maintain eye health.
If you’re not consuming enough vitamin C through your diet, it’s a good idea to consider a vitamin C supplement. Here’s what to look for when buying a vitamin C supplement.
