Vitamin C is one of the most potent antioxidants. It plays a huge role in cancer reduction. It also helps to normalize blood pressure and aids in the reduction of arterial clogging. Vitamin C plays a key role in our muscular-skeletal health and anti-aging pursuits, as well. This is due to its ability to support the production of collagen, helping us to both grow and repair. It also happens to be great at taking care of cold sores and hemorrhoids.
