theanine capsules

Common companion ingredients include magnesium, melatonin, valerian root, GABA, 5-HTP, ashwagandha, chamomile, lemon balm, hops, and tea catechins/EGCG.

Package quantities in these results include 30, 45, 60, and 120 capsules/servings.

Most listings are labeled for adults (often 18+). At least one product description in the set specifies availability for all ages.

Instructions vary by formula. Many products advise taking 1 capsule about 30–60 minutes before bedtime for sleep. Other listings recommend 1–2 doses (e.g., 1–2 tablets or 2 veggie capsules) taken daily, sometimes with a meal; timing and dose depend on whether the formula is a single-ingredient or multi-ingredient sleep blend.

Product details commonly mention third-party testing or certification, vegetarian/non-GMO or vegan labeling, and manufacture in cGMP facilities.

Daytime/focus formulas often contain L-theanine alone (commonly ~200 mg) and emphasize alert calm or 'wakeful relaxation.' Nighttime blends pair L-theanine with sleep-supporting ingredients such as melatonin, valerian root, GABA, chamomile, lemon balm, and hops to support sleep onset and quality.
