GABA side effects, gaba supplement - Does a GABA supplement help reduce anxiety symptoms
GABA or gamma-aminobutyric acid, discovered in 1950, is the most important and widespread inhibitory neurotransmitter in the brain. Excitation in the brain must be balanced with inhibition. Too much excitation can lead to restlessness, irritability, insomnia, and even seizures. GABA is able to induce relaxation, analgesia, and sleep. Barbiturates and benzodiazepines are known to stimulate GABA receptors, and hence induce relaxation. Several neurological disorders, such as epilepsy, sleep disorders, and Parkinson’s disease are affected by this neurotransmitter. For more GABA information.

GABA is made in the brain from the amino acid glutamate with the aid of vitamin
B6. GABA is available as a supplement in vitamin stores, but taking it in pill form is not
always an effective way to raise brain levels of this neurotransmitter because GABA cannot
easily cross the blood-brain barrier. Companies are searching for ways to place GABA in an
oil base in order to ease its entry across this barrier. Having said this, I
have spoken to a few people who feel that GABA helps reduce their anxiety. One
user takes GABA in the morning and says it takes the edge off his anxiety, and
the effects are noticed a few hours later.
GABA Summary
We have not come across few
studies regarding the use of GABA supplements in humans. We don't have a strong
opinion regarding the effectiveness of GABA supplements at this time.

Email questions and answers
Q. I would like to know whether GABA has any effect on hormones such as prolactin
or gonadotropin? And if GABA improves liver detoxication?
A. GABA supplement has not been tested in human long enough to know
what effect it would have on prolactin, gonadotropin or other hormones. We're
not sure what people mean when they use the word detoxification.
Q. In studying phycology and talking to my phycology
professors, they highly suggest against taking additional GABA and claim the
effects of any additional GABA supplement can cause many side effects and
neurological problems and that they and other doctors prescibe this to balance
out low levels , but if your levels are too high they give you medication to
reduce the level, problems such as causing low vitamin B6 levels which cause
seizures, not to mention withdrawal of the drug can result in GABA receptor
hypoactivity producing symptoms worse than the ones that the patient originally
sought treatment for. So my question is, why is GABA drug so glorified in the
bodybuilding community if its soo dangerous and possibly deadly to take?
Steroids are used in the medical community all the time but restricted from
bodybuilding for the same reasons GABA should be.
A. There is no evidence at this time that taking a GABA supplement
is harmful to the body, however human research with GABA supplement use is
lacking. We are not convinced GABA is a helpful product for bodybuilding. As far
as GABA use for relaxation, some people may notice the effects but many people
don't. Most supplements should not be used all the time, and if GABA is used
occasionally, we don't suspect any safety issues.
Q. Does GABA supplement help with
memory?
A. We doubt GABA pills improve memory.
Q. I was reading your information online regarding
gamma-Aminobutyric acid and felt compelled to write. I started taking GABA
supplements several months ago when a promotion at work resulted in high stress
and chronic insomnia. I had tried numerous other herbal sleep aids and nothing
helped in the least, but, seemingly, the GABA worked miraculously when I started
taking three 750 mg capsules right upon going to bed. And there was yet another
dramatic positive effect of the GABA. I suffer from chronic and constant
spasmodic cervical dystonia. After I started using the GABA the symptoms of the
dystonia all but completely went away. Interestingly, I had been taking GABA
every night for about four months and stopped suddenly about three weeks ago
when I went on a backpacking trip. After I returned from the trip I did not
begin taking the GABA again, within about a week my level of stress and anxiety
had skyrocketed again and the dystonia symptoms returned unabated (though the
symptom that led me to take the GABA in the first place, the insomnia, has not
returned.
A. Thanks for sharing this with us.
Q. Can you please explain what the following research
is saying? Does this mean that the use of alcohol lowers the normal level in
your body and a supplement of GABA (LTheanine) might be needed?
Alcohol effects on gamma-aminobutyric acid type A receptors: are
extrasynaptic receptors the answer? Life Sci. 2004 Nov 19;76(1):1-8.
GABA (A) receptors have long been implicated in mediating at least
part of the actions of ethanol in mammalian brain. However, until very recently,
reports of the actions of ethanol on recombinant receptors have required very
high doses of ethanol and animals lacking receptor subunits shown to be
important for ethanol actions in vitro did not support the view that these
subunits are crucial in ethanol actions. Recombinant GABA (A) receptors are
uniquely sensitive to ethanol, with a dose-response relationship mirroring the
well known effects of alcohol consumption on the human brain. Receptors
containing the delta subunit are thought to be located extrasynaptically and it
will be important to determine if these extrasynaptic GABA (A) receptor subunit
combinations mediate low dose alcohol effects in vivo.
A. It's too early to tell from this early research. Taking a GABA
supplement is not likely to replenish GABA receptors. One should consider
treating the whole body and symptoms of a condition rather than focusing on one
neurotransmitter or receptor.
