Gamma-aminobutyric acid, more commonly known as GABA, is classified as a neurotransmitter – a chemical that sends messages to the brain. Under stress, the body releases chemicals that signal the brain to initiate the fight or flight response. When the source of stress passes, the body releases other chemicals, such as GABA, to signal the brain to stop the fight or flight response. GABA supplements are non-sedating tranquilizers formulated to calm anxiety and relieve the effects of stress, such as insomnia. GABA is available in tablet, gel and powder form. Always consult your physician before starting any supplement program.
Speak with your doctor in order to determine the proper dosage for your condition. The dosage for insomnia is 500 to 1,000 mg approximately one hour before bed. The dosage for stress is 750 mg split into three daily doses.

Consume the GABA on an empty stomach for better absorption. For split doses, take the supplement approximately 60 minutes before eating your next meal or two hours after a meal. Drink a full glass of water to help the supplement dissolve. If you have trouble swallowing pills, you can use the powder form and dissolve it in water or juice.
Purchase GABA sublingual tablets for the quickest absorption into your bloodstream via the blood vessels under your tongue and in the cheeks.
Avoid taking GABA if you are taking prescription medication for anxiety, such as alprazolam or diazepam, or when taking medications that may cause drowsiness, such as prescription sedatives, muscle relaxants and certain antidepressants. Stop taking GABA if your anxiety or insomnia worsens or if you experience numbness or tingling around your mouth or in your arms and legs.
