L-茶胺酸是一種不易從日常飲食中獲取的胺基酸。其結構與神經傳導物質GABA和麩胺酸相似，口服進入人體後在大腦中發揮類似作用。
研究發現，L-茶胺酸有助於促進放鬆感，且不會引起嗜睡。它同時能維持健康的壓力水平和注意力持續時間。這些特性使其非常適合與咖啡因搭配使用，以減緩部分人攝取咖啡因後可能出現的緊張不適。例如，L-茶胺酸與咖啡因的組合已被證實能支持記憶力、專注力、活力及問題解決能力等認知功能。
Took one capsule with my evening tea and noticed my mind stopped racing within 30 minutes—the calm felt like a gentle wave instead of a sedative crash. The fact that it mimics GABA makes total sense to me now, since I woke up feeling rested rather than groggy.
I’ve been taking one capsule about an hour before bed and it genuinely feels like my brain finally hits the brakes instead of racing all night. The way it mimics GABA seems to smooth out that anxious edge without making me groggy the next morning.
My sleep has been noticeably deeper since adding this to my evening routine, and I love that it's an amino acid rather than another synthetic compound. The effects feel smooth and natural, like my brain just settles down on its own without any grogginess the next morning.
