Very little information is available about the safety of GABA (gamma-aminobutyric acid) supplementation. Some people may be more likely to experience problems with a medication or supplement than others. Therefore, you should talk with your healthcare provider prior to taking GABA if you:

Have any chronic medical condition
Are pregnant or thinking of becoming pregnant (see GABA and Pregnancy)
Are breastfeeding (see GABA and Breastfeeding).

You should also make sure to tell your healthcare provider about any other medicines you are taking, including prescription and nonprescription medicines, vitamins, and herbal supplements.

Specific GABA Safety Precautions and Warnings

Some warnings and precautions to be aware of concerning the safety of GABA include the following:

As a dietary supplement, GABA supplements are not as closely regulated as prescription or nonprescription drugs. They can be marketed without any evidence that they are either safe or effective. Do not assume that just because a product is sold or advertised in the United States that it is safe or effective. Make sure to look for GABA products from a reputable manufacturer. Your pharmacist is a good resource for information about which manufacturers are the most reputable.
If you have a chronic or severe medical condition, it is always a good idea to check with your healthcare provider before taking any medication or supplement, including GABA.
It is unknown if GABA is safe for use during pregnancy or breastfeeding (see GABA and Pregnancy and GABA and Breastfeeding).
