Why this form

Active form

One 200 mg capsule, no caffeine, no melatonin, no adaptogen stack and no proprietary blend.

Evidence in context and limitations

Intended role

Support relaxation, attention under stress and evening wind-down routines without promising treatment of anxiety or insomnia.

Small trials and systematic reviews suggest potential benefits for stress-related symptoms, relaxation and selected attention outcomes, particularly at 200-400 mg/day and sometimes with caffeine. Study sizes are limited and formulations vary.

Directions and time horizon

Adults take one capsule daily with or without food. Use during the day or in the evening according to personal response. Do not combine with alcohol or sedative medicines without professional advice.

Some studies examine acute use while others assess several weeks. Individual response can be subtle, and no fixed onset or sleep outcome should be promised.

Store tightly closed in a cool, dry place away from direct heat, moisture and light.

Quality and testing

HPLC assay ≥98% and enantiomeric identity confirming L-theanine rather than racemic material. Verify residual solvents, microbial quality and heavy metals. If Suntheanine® is used, obtain trademark authorization and current specification.

Interactions

Use caution with sedatives, blood-pressure medicines and other products intended to induce relaxation. Pregnancy and breastfeeding data are insufficient.

FAQ

Will it make me sleepy?

L-theanine is often described as non-sedating, but individual responses vary. Do not drive if drowsiness occurs.

Can I take it with coffee?

L-theanine has been studied with caffeine, but this product contains no caffeine. Consider total caffeine intake and personal sensitivity.

Can I use it at night?

Yes, if it suits your response, but the product should not be presented as a treatment for insomnia.

Why 200 mg?

Two hundred milligrams is common in human studies and allows a simple one-capsule serving.

Is it sourced from tea leaves?

The preferred material is fermentation-derived L-theanine for consistency and purity rather than extracted tea powder.
