GABA
POWDER (Gamma Aminobutyric Acid)
Gamma aminobutyric acid is a non-essential amino acid that has been the subject of hundreds of studies. Of particular interest for people involved in fitness and training is the fact that GABA stimulates the release of human growth hormone (hGH) during sleep. Higher levels of growth hormone results in increased muscle mass (leading to greater strength gains), fat loss, and possibly lower water retention. There also is evidence that greater hGH results in substantial improvements in tendon and ligament strength. As you age, your natural GH production decreases, so GABA is a very beneficial supplement. Of course, using GABA will not give you as great an effect as directly taking hGH - which is only available by prescription and very expensive - but it is effective. According to a study by the First Medical Clinic at the University of Milan, Italy, a dose of 5 grams - about a teaspoon can increase blood plasma levels by up to 550% within 90 minutes. Take it before going to sleep. GABA also inhibits, i.e., slows down, the firing of neurons, producing a calming effect similar to prescription drugs such as valium (which use the brain's GABA receptor), but with absolutely no addictive effect. Thus, GABA can be safely used for relaxation and as a sleep aid. Users have reported more restorative sleep as well as more vivid dreams. As little as 1/2 a gram combined with the B vitamins inositol and niacinamide is sufficient for this purpose.
