GABA has been shown in studies to release growth hormone, which increases lean body mass. Therefore, it is a very valuable supplement for body builders, powerlifters, and all types of fitness enthusiasts. GABA has also been shown to reduce stress and promote restful sleep.
GABA is best taken before going to sleep on a relatively empty stomach. By scheduling your dose of GABA at bed time, it works with the body's natural rhythms to help increase growth hormone production while sleeping. Most people will experience some benefits of GABA within two weeks and its full impact may be noticed after six to eight weeks.
