GABA, or gamma-aminobutyric acid, is the most important natural neurotransmitter found in the brain. Discovered in 1950, GABA was researched and tested before it ultimately gained the reputation as a chemical that could induce relaxation, analgesia, and sleep. Studies have been conducted, two specifically, regarding the use of the supplement and its effect on relaxation and immunity to stress.
The first study was conducted with 13 participants. The study set out to look at the relationship between GABA intake and brain wave activity. The results showed that the GABA had greatly increased brain alpha wave activity within 60 minutes of being orally administered (it had also, in turn, decreased beta waves). These results indicated that GABA not only increased the propensity for relaxation, but, also decreased overall anxiety levels within the experiment’s participants.
The second study looked at participants whom were placed in a “stressed out” mental state. This was done by asking them to cross a swaying bridge. The volunteers were divided into two groups; a placebo group and a group who was administered GABA treatments. Immunoglobulin A (IgA) levels in the saliva were tested throughout the experiment (lgA inhibits relaxation). In the end, it was determined that lgA levels were significantly higher in the group that had received the supplementation, when compared to the placebo group. The conclusion indicated once again, that gamma-aminobutyric acid could be used as a natural relaxant within 60 minutes of oral consumption.
Taking GABA supplements, usually in the amount of 2-5 grams daily, has also shown to help in other self improvement efforts (for many individuals). In addition to its stress reducing abilities, GABA is speculated to be beneficial for weight loss and fat burning; at type of 24/7 metabolism booster, some believe. It has also proven to increase blood Human Growth Hormone levels (HGH) in various studies. This is important to many body builders, as increased HGH levels typically lend to increased strength and muscle density. Since it is difficult for the supplement to cross the blood brain barrier, however, many skeptics have dispelled that the supplement is overly effective within the realms of weight loss or HGH production.
What is the best way to decide whether or not gamma-aminobutyric acid supplementation is for you? Consult a physician and try it! GABA has worked wonders for thousands of people worldwide. While its effects have been proven to reduce anxiety and increase relaxation, there is also a lot of evidence to argue that supplementation may be just as beneficial for insomnia, weight loss, and body building.
gamma-aminobutyric acid can be found it most health food and dietary supplement stores. Recommendations on dosage can be found directly on the GABA supplement label. However, it is highly recommended that you start off with a light dosage – typically less than 1-2 grams. To this point, few studies have been conducted on GABA effects and long term supplementation. Furthermore, you should note that there is no “standard dosage” for GABA within the health and dietary supplement industry. The supplement’s side effects, though very mild, have also been noted. Starting out small and gradually building your way up is the best way to go when using GABA supplements.
