Like all medication, taking too much GABA can and will cause you to experience side effects, ranging from mild to severe. To reduce the chances of experiencing side effects, it is recommended that you take natural GABA instead of synthetic ones. Be very cautious and take only the recommended dosages, or as your doctor instructs you.

Important Safety Information

Upon experiencing any of the above, discontinue use and contact your doctor immediately.

A sudden stop in taking GABA may cause withdrawal symptoms such as headaches, nausea, diarrhea, insomnia, and seizures.


It is highly recommended that you take natural GABA instead of synthetic ones. Please take a look at my post about the best natural gaba supplements.

Take GABA only in dosages that are recommended on the label, unless instructed otherwise by your doctor. GABA is an oral medicine, taken only in pill form and should be consumed with a large glass of water. The pill can be ingested on an empty or full stomach, but the same dosages must be taken each day. Should you miss a dose of GABA, take the next one at your earliest convenience, but never ingest two at the same time.
