Kava Dosage

A safe and effective kava dosage has not yet been established. The available dosing information for the herbal supplement is obtained from clinical studies and practical experience with the supplement. Most studies for treating anxiety used kava doses of 100 mg of a kava extract. Since there is some concern that kava can cause liver damage, people with liver problems should not take the supplement.

An Introduction to Kava Dosage

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 kava (Piper methysticum).
 

Reasonable Kava Dosing

Some information about kava dosing can be obtained from clinical studies and from practical experience with the supplement. Most studies of kava for anxiety used doses of 100 mg of a kava extract (standardized to 70 percent kava-lactones, twice as strong as most commercially availably extracts). "Standardization" means that the kava extracts were tested to make sure they had a standard amount of kava-lactones (thought to be the active chemical components of kava).
 
It is important to note that a safe kava dosage has not been established, and there is some concern that kava can cause liver damage. In fact, kava has been banned in several countries due to such problems. People who already have liver problems should not take kava.
 

General Information on Dosing With Kava

Some considerations for people taking kava include:
 
  • Since the manufacturing of supplements (such as kava) is not closely regulated, it is important to choose a trustworthy manufacturer for kava supplements. Your pharmacist can help you choose a reputable manufacturer.
     
  • 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 kava.
     
  • If you are unsure about anything related to your dosage or kava dosing in general, please talk with your healthcare provider.
