Asian Ginseng for Sports & Fitness

Why Use

Asian 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, several 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 energizing 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.

Dosage & Side Effects

Asian Ginseng

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 standardized 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

Side Effects

Used in the recommended amounts, ginseng is generally safe. In rare instances, it may cause over-stimulation and possibly insomnia.10 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.

Interactions with Supplements, Foods, & Other Compounds

Consuming caffeine with ginseng increases the risk of over-stimulation and gastrointestinal upset.

Interactions with Medicines

Certain medicines interact with this supplement.

Types of interactions: Beneficial Adverse Check

Replenish Depleted Nutrients

  • none

Reduce Side Effects

  • none

Support Medicine

  • Chlorphen-Pyrilamine-PE Tannts

    Laboratory studies have shown that compounds found in Panax ginseng enhance the ability of phenylephrine to constrict blood vessels.11 Controlled studies are necessary to determine whether taking Panax ginseng at the same time as phenylephrine will enhance the beneficial effects of the drug.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • Influenza Virus Vaccine

    In a randomized, double-blind study, 227 people received influenza vaccine plus 100 mg of standardized extract of Asian ginseng (Panax ginseng) or placebo two times per day for four weeks before and eight weeks after influenza vaccination.12 Compared with placebo, Asian ginseng extract was reported to prevent colds and flu, improve immune cell activity, and increase antibody levels after vaccination.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.

Reduces Effectiveness

  • none

Potential Negative Interaction

  • Imatinib

    A case report suggested that Panax ginseng may inhibit the metabolism of imatinib, potentially increasing the toxicity of the drug. People taking imatinib should therefore not take Panax ginseng.13

  • Ticlopidine

    Ginseng (Panax ginseng) was associated with a decrease in warfarin activity in a case study.14 This report suggests that ginseng may affect parameters of bleeding. Therefore, people taking ticlopidine should consult with a physician knowledgeable about botanical medicines before taking Asian ginseng or eleuthero/Siberian ginseng (Eleutherococcus senticosus).

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • Warfarin

    Asian ginseng was associated with a decrease in warfarin activity in a case report.15 However, in a clinical trial, no interaction was seen between Asian ginseng and warfarin.16 An animal study also found no significant interaction between warfarin and pure ginseng extract.17 Nevertheless, persons taking warfarin should consult with a physician knowledgeable about botanical medicines if they are considering taking Asian ginseng or eleuthero/Siberian ginseng (Eleutherococcus senticosus). A 1999 animal study did not reveal any significant interaction between warfarin and pure ginseng extract.18

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
