Vitamin C Supplements are crucial for a bariatric patient. Vitamin C is an antioxidant, which means it protects the body against damage from free radical molecules, oxygen molecules that steal electrons from other, including DNA. But vitamin C’s most important function is to maintain a protein called collagen, which helps form connective tissue in the bones, skin, ligaments and other tissue. Because of this, vitamin C is important in wound healing, especially the wounds that were inevitably sustained during the bariatric surgery itself. Without the right levels of vitamin C, the surgical wounds won’t heal well. Vitamin C also helps the body make red blood cells and prevents hemorrhaging. A lack of vitamin C leads to blood clots which may then result in strokes and heart attacks.
