Caffeine and vitamin C for strength in tired teens
Part of Mental health clinical trials.
This trial tests whether taking caffeine and vitamin C together can help 18- and 19-year-olds who feel mildly mentally tired do better at lifting weights and holding strength longer. It may improve your performance if you have low energy and do not already use a lot of caffeine.
