How Much Is Usually Taken by Athletes?

An extract of American ginseng was found ineffective at improving endurance exercise performance in untrained people after one week’s supplementation in a double-blind study.1

Standardized extracts of American ginseng, unlike Asian ginseng, are not available. However, dried root powder, 1 to 3 grams per day in capsule or tablet form, can be used.2 Some herbalists also recommend 3 to 5 ml of tincture three times per day.
