    GABA: The Forgotten Amino Acid

    GABA: The Forgotten Amino Acid

    GABA (gamma-aminobutyric acid) supplements have been around for quite some time. Their claim to fame has been to help with relaxation, improve sleep, improve your mood, as well as improve your focus. GABA is a naturally-occurring amino acid and inhibitory neurotransmitter found in our cells. A new study from Japan is actually showing the potential to now be able to add lean muscle mass through GABA supplementation.

    Researchers may have opened the door to new lean muscle growth for us all. For their new study they used 26 participants – men between the ages of 26 and 48 who use resistance training regularly. They had them use 10g of whey protein each day and depending on the group, had them either add 100mg of PharmaGABA or nothing at all. The PharmaGABA product is manufactured by Pharma Foods International who controls over 70% of the GABA market over in Japan. The study using this form of GABA lasted a total of 12 weeks where the participants trained twice a week.

    What-is-Gaba

    The results of the study were astonishing. After 12 weeks the group who used the whey and GABA had more than double the resting plasma growth hormone levels at week 4, 8, and 12 of the study when compared to their individual baseline values taken at the beginning as a baseline. By comparison, the “whey only” group showed only an increase in resting plasma growth hormone levels at week 8 of the study. In addition, the group who used whey and GABA showed an increase in lean mass of 1,340g whereas the control group only gained 146g.

    Researchers said that, “combined ingestion of GABA with whey protein increased muscle mass more effectively than ingestion of whey protein alone in resistance-trained men. Therefore, dairy supplementation with GABA may be a useful addition to whey protein for augmenting exercise-induced muscle hypertrophy.”

    Below is a chart from the study that shows the difference in lean mass measured by using dual-energy x-ray absorptiometry (DXA). Here you can see the considerable difference between the whey protein group and the whey protein with GABA group.

    Relaxation and immunity enhancement effects of gamma-aminobutyric acid (GABA) administration in humans.

    Abstract

    The effect of orally administrated gamma-aminobutyric acid (GABA) on relaxation and immunity during stress has been investigated in humans. Two studies were conducted. The first evaluated the effect of GABA intake by 13 subjects on their brain waves. Electroencephalograms (EEG) were obtained after 3 tests on each volunteer as follows: intake only water, GABA, or L-theanine. After 60 minutes of administration, GABA significantly increases alpha waves and decreases beta waves compared to water or L-theanine. These findings denote that GABA not only induces relaxation but also reduces anxiety. The second study was conducted to see the role of relaxant and anxiolytic effects of GABA intake on immunity in stressed volunteers. Eight acrophobic subjects were divided into 2 groups (placebo and GABA). All subjects were crossing a suspended bridge as a stressful stimulus. Immunoglobulin A (IgA) levels in their saliva were monitored during bridge crossing. Placebo group showed marked decrease of their IgA levels, while GABA group showed significantly higher levels. In conclusion, GABA could work effectively as a natural relaxant and its effects could be seen within 1 hour of its administration to induce relaxation and diminish anxiety. Moreover, GABA administration could enhance immunity under stress conditions.

    GABA, a forgotten gliotransmitter

    Abstract

    The amino acid gamma-aminobutiric acid (GABA) is a major inhibitory transmitter in the vertebrate central nervous system (CNS) where it can be released by neurons and by glial cells. Neuronal GABAergic signaling is well characterized: the mechanisms of GABA release, the receptors it targets and the functional consequences of their activation have been extensively studied. In contrast, the corresponding features of glial GABAergic signaling have attracted less attention. In this review, we first discuss evidence from the literature for GABA accumulation, production and release by glial cells. We then review the results of recent experiments that point toward functional roles of GABA as a “gliotransmitter”.

    Gaba is good stuff. 1g of GABA and 3mg of melatonin works really well. Just don’t take melatonin every night remember it’s a hormone and just like if we take testosterone on a consistent basis if we take melatonin consistently out bodies will stop producing it. I learned this the hard way In the military I took melatonin every night for about 3 months straight. We pulled into port and I didn’t take my melatonin with me and I didn’t sleep for three straight days before I finally fell asleep for a few hours. I had no clue what was wrong with me at first until I went to medical and got drug tested and questioned like I killed someone we finally linked it to the melatonin. It was definitely a crazy experience for sure and what’s really crazy is mentally I wasn’t tired at all. My body was tired as shit but mentally I felt fine.
