L‑theanine is a non‑protein amino acid (i.e. an amino acid that does not play a role in the formation of body proteins). Naturally found in green tea (Camellia sinensis), where it is traditionally used to promote relaxation and mental performance. Contributes to normal heart function and fat metabolism.
Why don't you normally find out the source of L‑theanine in other products? Either the manufacturer doesn't know at all, or it is synthetically produced L‑theanine. The Vilgain source of L‑Theanine is a highly concentrated 40% green tea extract.
When you take these substances at the same time, the onset of caffeine isn't as sharp and the effects from it linger for longer. Studies also show that combining these 2 substances boosts brain performance more than taking the substances separately.
Recent studies [3] have investigated L‑theanine in relation to its effects on the central nervous system, where it could stimulate the production of α-brain waves inducing feelings of relaxation and release.
Promotes relaxation without a dampening effect on cognitive function.
Studies show that the optimal dose of L‑theanine is 100‑200 mg per serving. This dose would be approximately equivalent to 10‑20 cups of green tea. However, you can also find it in one capsule of Vilgain L‑Theanine. The effects of green tea kick in as early as 30 minutes after consumption and last up to several hours.
