Asian Ginseng for Sports & Fitness

Common names: Korean ginseng, Chinese ginseng

Botanical name: Panax ginseng

Why do athletes use it?*

Some athletes say that Asian ginseng

helps reduce fatigue.

What do the advocates say?*

Extensive but often poorly designed studies have been conducted on the use of Asian ginseng (Panax ginseng) to improve athletic performance.¹ ² While some early controlled studies suggested there might be benefits, a few recent double-blind trials have found no significant effects of Asian ginseng on endurance exercise.³ ⁴ ⁵

Historically, it has been used to help people who are fatigued feel less lethargic. The energising effects of Asian ginseng only last while it is in your system. If you are consistently feeling tired, it’s best to pinpoint the reason for your fatigue.

How much is usually taken by athletes?

In some of the above studies, it is possible that ginseng was used in insufficient amounts or for an inadequate length of time; a more effective regimen for enhancing endurance performance may be 2 grams of powdered root per day or 200 to 400 mg per day of an extract standardised for 4% ginsenosides, taken for eight to twelve weeks.⁶ Short-term intense exercise has also not been helped by Asian ginseng according to double-blind trials,⁷ ⁸ but one controlled study reported increased pectoral and quadriceps muscle strength in non-exercising men and women after taking 1 gram per day of Asian ginseng for six weeks.⁹

Are there any side effects or interactions?

Used in the recommended amounts, ginseng is generally safe. In rare instances, it may cause over-stimulation and possibly insomnia.¹⁰ Consuming caffeine with ginseng increases the risk of over-stimulation and gastro-intestinal upset. People with uncontrolled high blood pressure should use ginseng cautiously. Long-term use of ginseng may cause menstrual abnormalities and breast tenderness in some women. Ginseng is not recommended for pregnant or breast-feeding women.

Are there any drug interactions?
Certain medicines may interact with Asian ginseng. Refer to drug interactions for a list of those medicines.

Parts used and where grown

Asian ginseng is a member of the Araliaceae family, which also includes the closely related American ginseng (Panax quinquefolius) and less similar Siberian ginseng (Eleutherococcus senticosus), also known as eleuthero. Asian ginseng commonly grows on mountain slopes and is usually harvested in the fall. The root is used, preferably from plants older than six years of age.
