High dose Vitamin C
Vitamin C (Ascorbic Acid) is a crucial molecule in humans. It has very high antioxidant capacity and is involved in numerous reactions including the formation of collagen which is the structural base for all of our connective tissues including healthy skin, cartilage and blood vessel walls. It also supports a robust immune system and is necessary for efficient energy production. Several studies have shown that vitamin C not only complements active cancer treatment but also decreases the side effects of both chemotherapy and radiation. Citations are available.
