Mental Health Home > Gamma-Aminobutyric Acid Dosage

Because gamma-aminobutyric acid is classified as a dietary supplement, there is little, high-quality information about the safest and most effective gamma-aminobutyric acid dosage. Therefore, it is reasonable to follow the directions on the label of your particular gamma-aminobutyric acid product. If you decide to use gamma-aminobutyric acid supplements, make sure to choose a product made by a trustworthy manufacturer.

An Introduction to Gamma-Aminobutyric Acid Dosages

As is the case with many dietary supplements, there is no clearly established safe and effective dose for gamma-aminobutyric acid (GABA) at this time. In fact, a "typical" dosage cannot even be recommended.

Is There a Reasonable Dose of Gamma-Aminobutyric Acid?

There are a few different reasons why it is difficult to recommend a gamma-aminobutyric acid dosage. Unlike prescription or nonprescription drugs, there is no standard recommended dose for dietary supplements, including gamma-aminobutyric acid. In addition, because gamma-aminobutyric acid supplementation has been studied very little in humans, no real data is available to support any particular amount as either safe or effective.
Because there is little, high-quality information about gamma-aminobutyric acid dosing, it is a good idea to follow the instructions on the label.

General Information on Dosing With Gamma-Aminobutyric Acid

Some considerations for people taking gamma-aminobutyric acid include the following:
  • If you decide to take a gamma-aminobutyric acid supplement, it is important to choose a trustworthy manufacturer (supplements are not regulated as closely as drugs). Your pharmacist is a good source for information about which manufacturers are most reliable.
  • If you have any chronic health problems or take any prescription medications, it is a good idea to check with your healthcare provider before taking gamma-aminobutyric acid.
  • If you are unsure about anything related to gamma-aminobutyric acid dosing, please talk with your healthcare provider.
