Now Foods GABA 500 mg is a single ingredient dietary supplement. Its core advertised benefit is that it provides a natural calming effect. The manufacturer is Now Foods, one of the largest manufacturers of dietary supplements, vitamins, sports nutrition, and health care products in the United States.

The main ingredient of the supplement is GABA (gamma aminobutyric acid), a non-essential amino acid (meaning it is synthesized by the body). It is found mainly in the human brain and eyes. GABA is an inhibitory neurotransmitter and plays an important role in regulating neuronal excitability throughout the nervous system.

It is sometimes referred to as the “brain’s natural calming agent”. However, there is insufficient evidence that taken orally it preserves these properties, since most research indicates that GABA does not cross the blood–brain barrier at significant levels.

According to the manufacturer, Now Foods Gaba 500 mg provides only the naturally occurring form as found in food and in the body.

Now Foods Gaba 500 mg Ingredients

Now Foods GABA 500mg includes the following ingredients: Vitamin B-6 (from Pyridoxine Hydrochloride), GABA (Gamma Aminobutyric Acid).

Product Features

Now Foods GABA 500 mg is a single ingredient dietary supplement which promotes a calming effect throughout the entire body.

GABA is an essential amino acid for the well functioning of the nervous system, possessing neuro-inhibitory properties. Although there is insufficient evidence which point to its effectiveness when taken orally, GABA supplements are prescribed for relieving anxiety, reducing symptoms of premenstrual syndrome (PMS), improving mood, treating attention deficit-hyperactivity disorder (ADHD), burning fat, promoting lean muscle growth.

Although Now Foods does not disclose any potential side effects, our readers should know that there isn’t enough information available to know whether GABA is safe for use or not. Pregnant and breastfeeding women are advised not to use, out of precaution.

The daily dosage for Now Foods Gaba 500 mg is 1 capsule taken 2 to 3 times as needed, preferably with juice or water on an empty stomach.

  • The manufacturer is a large company with a good reputation
  • Reasonable price (minimum 2 months supply 200 capsules for approximately $20)


  • The product has not been approved by the FDA
  • Insufficient research that GABA may be effective taken orally.


Now Foods GABA 500mg promotes nervous tension release and an overall calming effect. The supplement is a single ingredient formula. GABA is one of the most important amino acids in the brain and is known for its natural calming effect. However, there is no conclusive evidence towards it effectiveness if taken orally, since research shows GABA only crosses the blood-brain barrier to at insignificant levels.

The manufacturer offers little information on potential harmful side effects or drug interactions; therefore it is our recommendation to seek medical council prior to starting using the supplement.

    My 11 years son was diagnosed with ADHD and his pediatrician recommended Dr Amen’s book “Healing ADHD” and it was very helpful. Gaba was one of the supplements recommended in the book for my son’s form of ADHD. The product appears to be effective but it is difficult to conclude anything since he is just 11 and my only conclusions are from observations.
