Ginseng has been around for ages, but a lot of people have tried it without getting results. If you’re in that category, perhaps you didn’t take it for a long enough period.
According to an article in the American Journal of Clinical Nutrition (72:624s-636s; 2000), ‘Controlled studies of Asian ginseng found improvement in exercise performance when the following conditions were true:
1) Study duration was more than eight weeks.
2) Standardized root extracts were used.
3) The daily dose was more than one gram of dried root or the equivalent (400 milligrams dried-root extract).
4) The study involved large numbers of subjects.
The authors also said, ‘Improvements in muscular strength, maximal oxygen output, work capacity, fuel homeostasis, serum lactate, heart rate, visual and auditory reaction times, alertness and psychomotor skills have also been documented.’ Remember, if you decide to try ginseng, give it more than eight weeks before you determine whether it’s beneficial for you.
