L-Theanine Enhances Focus (Nootropic Effects)

L-Theanine Enhances Focus (Nootropic Effects) L-theanine is an amino acid analogue structurally similar to glutamate and is contained in green, black, and oolong tea, comprising about 1-3% of the dry weight of tea leaves. A single cup of liquid tea contains 5-85 mg of L-theanine, depending on the type, quality, and preparation of the tea. L-theanine readily crosses the blood-brain barrier and is traditionally used as a relaxation-promoting agent. Animal studies have shown that L-theanine inhibits glutamate receptors while increasing dopamine release, gamma-aminobutyric acid (GABA) concentrations, and serotonin levels in the brain. 🌿 BUY L-THEANINE HERE: 🌎 Want More Health Hacks? 🧠JOIN MY FREE NOOTROPICS COURSE: 🎙My Podcast: 📲 My Instagram: https://ww
