gaba l theanine

They appear as oral capsules, tablets, and softgels; in powdered drink mixes; and as topical patches.

Serving amounts vary by product. In this set, GABA ranges from single-digit milligrams up to hundreds of milligrams (examples include 4 mg, 100 mg, 125 mg, and 750 mg). L‑theanine ranges from a few milligrams up to about 200 mg, with 100 mg appearing in several formulas.

Directions vary by form: oral tablets/capsules often list adult dosing such as one tablet once or 1–2 times daily, specific bedtime timing (about 30–60 minutes before bed), or softgels taken as needed (for example, two softgels). Powders use teaspoon measures for mixing. Patches are applied to clean, dry skin per the product instructions.

They are marketed mainly for relaxation and stress relief and for sleep support (improving sleep quality and easing sleep onset). Some formulations also mention focus, emotional balance, or cortisol support.

Patches are applied to clean, dry skin and list measured ingredient amounts per patch—avoiding swallowing—with some product copy noting quicker onset and multi‑hour duration. Oral forms are swallowed (capsules, tablets, softgels) or mixed as powders and use measured oral dosing instructions.
