A single-ingredient L-theanine, 200 mg per capsule.
L-theanine is the amino acid found in tea leaves, studied for promoting alpha-wave activity (the relaxed-alert brain state) without sedation. It is researched both for calm focus during the day and, paired with magnesium L-threonate, for sleep onset. Pure Encapsulations supplies it as a hypoallergenic single-ingredient capsule.
