A tea-derived amino acid studied for supporting calm, steady focus without drowsiness.
L-Theanine is an amino acid found primarily in tea leaves, studied for supporting calm, focused mental states without sedation.
It supports the spray's calm-and-focus layer, rounding out the formula beyond its respiratory-targeted ingredients.

This describes general research on L-Theanine itself, not the finished BreatheEaseX or CardioEaseX product, which hasn't been the subject of its own clinical trial. See the full ingredients list or the kit overview for more.
