l theanine focus

Most L-theanine supplements provide about 100–200 mg per serving. Multi-ingredient or combo formulas often list 100 mg per serving, while single-ingredient capsules commonly provide 200 mg.

L-theanine is often paired with calming or cognitive-support ingredients and minerals. Common combinations include magnesium, GABA, 5‑HTP, ashwagandha, B vitamins, and other nootropic or adaptogenic extracts.

Several listings emphasize vegan and non-GMO formulations, and at least one explicitly states the capsules are free from gluten.

Package sizes vary, but common counts observed include 30, 60, 90, and 120 capsules or servings.

Customer review summaries report that some users notice improved focus and mental clarity, while others report better sleep quality or increased relaxation. Reviews also commonly comment on product quality, flavor (for gummies or powders), and ease of use.
