Although the most safe and effective ginseng dosage has not been established yet, studies suggest that 200 mg daily seems to be a reasonable dosage for most uses. Since there are no set dosing guidelines for the supplement, it is best to look for a ginseng dose that has been "standardized" for the ginsenoside content.
It is important to note that unlike medications (for which the standard doses have been well established), there is less information for determining the best dose for supplements, including ginseng.
This article refers to Panax ginseng (also known as Asian ginseng, Chinese ginseng, and Korean ginseng). This type of ginseng should not be confused with American ginseng or Siberian ginseng, which are entirely different herbs.
Clinical studies have most often used a ginseng dose of 200 mg per day, although ginseng supplements are available in a wide range of doses. This appears to be a reasonable ginseng dose for most uses, although more research is required before the most safe and effective ginseng dosages can be established.
It may be a good idea to look for a ginseng dosage that has been "standardized" for the ginsenoside content. This means that it has been tested to make sure that the supplement contains a certain specified amount of ginsenosides (some of the active components in ginseng). Unstandardized supplements may contain vastly different amounts of ginsenosides, even if the overall dose of ginseng is the same.
Some considerations for people taking ginseng include:
- Since the manufacturing of supplements (such as ginseng) is not closely regulated, it is important to choose a reputable manufacturer for ginseng supplements. It is a good idea to look for the "USP" symbol, since this means that the supplement has been tested and contains the right ingredients in the right amounts (there have been reports that many ginseng supplements actually contain little or no ginseng). Reputable manufacturers are more likely to consistently standardize their products.
- If you have any chronic health problems or take any prescription medications, it is probably a good idea to check with your healthcare provider before taking ginseng.
- If you are unsure about anything related to your dosage or ginseng dosing in general, please talk with your healthcare provider.
