L-Theanine – more than just a relaxation amino acid<\/strong><\/p>\n

L-Theanine is typically known for its benefits on\u00a0focus,\u00a0relaxation, memory,\u00a0<\/strong>and\u00a0calm alertness<\/strong>. While these benefits are pretty well documented and enjoyed by many, there is actually more to this great Theanine story.<\/p>\n

Theanine, which is an abundant amino acid found predominantly in\u00a0green tea<\/strong>, has also been found to have the benefits of\u00a0lowering<\/strong>\u00a0cholesterol<\/strong>,\u00a0bile acid regulation,<\/strong>\u00a0liver protection<\/strong>,\u00a0metabolic improvement<\/strong>, and\u00a0anti-obesity\u00a0<\/strong>(sources in references section below).<\/p>\n

Now, back to the cognitive benefits. Instead of regurgitating the same old story, we’ll start off with some quotes from one of our greatest influences, the late and great Dr. Ray Peat.<\/p>\n

\u00ab\u00a0The tea amino acid, theanine, suppresses serotonin by\u00a0supporting the effects of GABA<\/strong><\/em>.<\/strong>\u00a0\u00bb<\/p>\n

Further<\/p>\n

\u00ab\u00a0The GABA system\u00a0restrains the production of cortisol<\/strong>, which is typically increased in depression. GABA-supporting drugs that had been used to treat epilepsy are turning out to have\u00a0anti-depressive<\/strong>,\u00a0mood-elevating<\/strong>\u00a0effects<\/em>\u00a0\u00bb<\/p>\n

\u00ab\u00a0Drugs (such as piracetam) that promote GABA’s effects are called \u00ab\u00a0nootropins,\u00a0\u00bb or\u00a0cognitive enhancers<\/strong>, and have been used to treat brain damage and mental retardation\u00a0\u00bb<\/em><\/p>\n

Ray understood deeply the interplay in these hormonal and neurotransmitter systems, which is how he was able to synthesize the benefit of Theanine through his knowledge of GABA, serotonin, and glutamate (from his May 2008 newsletter: The GABA System, defenses, and tissue renewal).<\/p>\n

This provides us with a novel perspective on how Theanine may be able to achieve its benefits on\u00a0cognition, memory, mood, focus, relaxation,\u00a0<\/strong>and\u00a0neuroprotection<\/strong>.<\/p>\n

Next, its benefits on the liver are documented but seldom talked about. Two studies in specific show L-Theanine\u00a0preventing alcoholic liver injury<\/strong>\u00a0by increasing the antioxidant capacity of liver tissue, and the\u00a0slowing of liver aging<\/strong>\u00a0by reversing inflammation, oxidative stress, and inhibiting advanced glycation end-products.<\/p>\n

A third study showed\u00a0protective effects on acute liver injury<\/strong>\u00a0by normalizing the hypothalamus-pituitary-adrenal (HPA) axis hyperactivity, as well as lowering lipopolysaccharide-induced inflammatory response markers such as C-reactive protein, nitric oxide, TNF-A, and IL-10.<\/p>\n
