No extras needed: At a healthy, young age of 18 years, an athlete has a big appetite and eats plenty. If he eats a wide variety of healthy, natural foods, he will get all the vitamins he needs from his foods. Taking one multivitamin for adults, once a day, is fine to do. No other supplements are needed. Watching his own body, to avoid overuse injuries, can help keep him in good shape the whole season.
