If you want calm focus without drowsiness, this pairs **L-Theanine** at 200 mg with **Lemon Balm Extract** at 300 mg — both dosed right at their most commonly studied levels. The 200 mg theanine dose is the exact amount used in most relaxation and focus research, so you're getting the full studied effect in a single capsule.

The lemon balm extract is standardized to rosmarinic acid and hydroxycinnamic acid, the active compounds linked to its mild calming properties. At 300 mg you're at the low end of the clinical range (300–600 mg), and the label allows a second capsule daily, which would bring you to 600 mg — the top of the studied dose.

Keep in mind that lemon balm has limited clinical evidence — only a handful of small trials support its calming effects. If you're dealing with significant stress, one capsule daily gives you a gentle starting point, but the research behind this herb is still catching up to its traditional reputation.
