GABA is a chemical messenger that slows down nerve activity in the brain. The brain makes it naturally. Whether an oral supplement enters the brain directly is still an open question, but many people feel calmer and more relaxed after taking it.
People use GABA to fall asleep faster and to take the edge off everyday tension. They swallow a dose 30 to 60 minutes before bed or right when stress spikes. The effect usually rolls in within an hour.
Common servings land between 250 and 750 mg. You can take GABA on an empty stomach or with a meal. Do what your product label tells you.
GABA can make you drowsy. Skip driving until you learn how your body handles it. Check with a healthcare professional if you already take blood pressure pills or sedatives.
