GABA is a dietary supplement marketed to help reduce stress, promote restful sleep and increase lean body mass.The formula is manufactured by Ultimate Nutrition, a U.S. based company founded in 1979 by Victor H. Rubino, one of the most popular amateur power lifters at that time. The company develops and markets various sports and athletic performance dietary supplements, including pre and post workout amino-acids, protein powders, carbohydrate powders, and various types of fat burners

The formula is recommended to people having trouble sleeping and people who seek to achieve a general state of wellbeing. A special category of consumers targeted by GABA includes body builders, power-lifters, martial artists, runners, and other athletes of all shades.


1) What is GABA?

GABA is based on the amino acid Gamma Amino Butyric Acid or GABA. GABA is a primary inhibitor neurotransmitter in the brain, where it works to prevent the over-firing of nerve cells and hence promotes relaxation. Due to its calming effect, GABA is mostly used to treat conditions that affect mood such as bipolar disorder (as low levels of GABA have been observed in patients suffering from this condition) or depression. Several studies have indicated GABA may help relieve symptoms of anxiety disorders such as panic attacks or OCD (obsessive compulsive disorder).

Other medical benefits include ADHD, Premenstrual Syndrome (PMS), epilepsy, hypertension and blood pressure. However, GABA supplements are not as effective as natural GABA, since they cannot cross the blood brain barrier. GABA is also known to increase production of the Human Growth Hormone, known to influence muscle mass growth. This is why GABA is popular with weight lifters and sports enthusiasts. Further research is needed to prove its benefits, as no conclusive clinical evidence is yet available.

GABA is generally considered side effects free, but may sometimes cause drowsiness. Although there are no known interactions with other drugs, a healthcare provider’s advice is generally recommended in case of GABA supplements.

3) Does GABA Work?

Also, its calming effects have proved reliable in treating conditions which affect bipolar disorder (patients suffering from this disorders possess low GABA levels), depression and mood control. Moreover, some studies showed that GABA might have a positive effect in relieving symptoms of anxiety disorders like obsessive-compulsive disorders (OCD) or panic attacks.

Besides the previously mentioned disorders, GABA may also prove reliable in treating Premenstrual Syndrome, hypertension, ADHD, epilepsy, and blood pressure. Unfortunately, GABA supplementation is not as effective as natural GABA because it cannot cross the BBB (blood brain barrier). Research revealed that GABA has a role in increasing production of HGH (human growth hormone) that influences mass muscle development. Therefore, GABA is a very popular ingredient among sports enthusiasts as well as weight lifters. However, further research is required mainly due to the lack of clinical evidence.

GABA is advertised to help relief symptoms harmful effects of daily stress, anxiety, depression or trouble sleeping. Consumer reviews report a good value for money and claim the formula is effective in delivering its marketed benefits.

Even though I’m a female and I don’t want to gain body mass, I’ve tried this supplement because I had some troubles sleeping. I’m not saying it cured them all, but it definitely helped.
