Vitamin C
Water-soluble vitamin from fruit and vegetables that contributes to normal collagen formation and increases non-haem iron absorption.
What the research shows
Shown, with a clear condition or a limited scope.
Vitamin C contributes to maintaining the normal function of the immune system during and after intense physical exercise. That statement appears on the European list, at an intake of 200 mg per day in addition to the recommended daily intake. Levine (1996) showed that blood levels saturate at around 200 mg per day, so higher doses mostly end up in urine.
Who it makes sense for: Athletes during and after intense exercise, and people who eat little fruit and vegetables.
