Description

L-Theanine is an amino acid found almost exclusively in the leaves of Camellia sinensis, the tea plant, and is largely responsible for the calm, focused quality that distinguishes tea from coffee despite having similar caffeine content. It is structurally similar to glutamate and GABA, and it has been studied for its role in supporting alpha brain wave activity, associated with alert but relaxed mental focus, the kind you want during a productive morning or a demanding afternoon.*

L-Theanine supports a calm, steady mindset, non-drowsy, making it a versatile daily supplement.* It works equally well as a morning focus aid alongside caffeine, or as an afternoon and evening supplement for those who want to take the mental edge off a demanding day without reaching for something sedating.

Double Wood's formula delivers 200mg per capsule, the dose most consistently used in published research on L-Theanine's effects on calm focus, relaxation, and alpha wave activity.* Every batch tested. Third-party tests by ISO/IEC 17025 accredited labs. COAs published openly. For daytime use, L-Theanine pairs naturally with Rhodiola for a calm focus routine that also supports stamina and resilience during everyday demanding moments. For evening use, Magnesium Glycinate is the most natural complement, supporting physical relaxation and nervous system ease alongside L-Theanine's mental calm.*
