When you're on overload this holiday season (or any time of the year) and feeling very anxious, it could be because you're brain is short on its main calming neurotransmitters.
GABA, an amino acid also known as gamma-aminobutyric acid, helps the brain, which is constantly being bombarded with loads of sensory information, filter out the nonessentials and helps improve mental focus. This, of course, leads to less anxiety.
When GABA levels are low, the extraneous isn't being filtered out so you feel stressed.
Japanese researchers have found that taking GABA supplements reduces anxiety and promotes relaxation. Further research has found that low levels of GABA is associated with depression and insomnia.
You can take 200 mg of GABA up to three times a day, but to increase it's benefits you may also want to combine it with 100 mg of L-theanine and B-complex.
Additionally, drinking green tea can help increase your GABA levels. It contains the amino acid L-theanine, a GABA booster.
