Collagen supplements cannot be routinely recommended, given the unconvincing evidence base. However, there are foods we can eat to help boost our body’s own collagen production. For example, vitamin C appears to stimulate collagen production from human skin cells. Defective wound healing has long been known as a major manifestation of scurvy, the vitamin C-deficiency disease. In a series of grisly experiments, British conscientious objectors during World War II were subjected to cuts and stab wounds after being randomized to different levels of vitamin C. The researchers found that the average daily vitamin C intake to prevent weak scar formation was about 95 mg, which is higher than the current recommendations––but you can get all of that from half a bell pepper. What about for wrinkles? Higher vitamin C intakes were associated with lower odds of a wrinkled appearance in a study of 4,000 middle-aged American women.
