Benefits of pure l theanine powder
L-Theanine is a natural non-protein amino acid, mainly found in tea (especially green tea), and it has unique physiological regulatory functions. Its mechanism of action involves multiple levels such as neurotransmitter regulation, antioxidation, and metabolic intervention.
1.Regulate the nerves and promote mental health
Theanine can relieve anxiety and stress, pass through the blood-brain barrier, increase the levels of GABA, dopamine and serotonin, and inhibit the excessive excitement of glutamate. It can enhance concentration while reducing palpitations and tension
2.Enhance cognition
Theanine can improve working memory and reaction speed. By inhibiting beta-amyloid protein aggregation and oxidative stress, it can assist in the prevention of Alzheimer's disease.
3.Antioxidant and anti-inflammatory
Theanine directly neutralizes ROS (reactive oxygen species) and RNS (reactive nitrogen species), protecting cell membrane and mitochondrial functions. The combination of EGCG can enhance antioxidant effects. At the same time, it can assist in the treatment of chronic inflammation-related diseases such as arthritis and skin inflammation
4.Regulate immunity
Theanine can enhance immunity and improve antiviral capacity by activating the functions of T lymphocytes and natural killer (NK) cells. Therefore, supplementing theanine during the flu season can reduce the risk of infection
5.Regulate metabolism
Theanine can help with weight management, inhibit the expression of fat synthase and reduce the accumulation of visceral fat. At the same time, it can regulate blood sugar by enhancing insulin sensitivity and delaying sugar absorption
