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.
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 a single dose, while others assess use over several weeks. Individual response and timing vary.
Store tightly closed in a cool, dry place away from direct heat, moisture and light.
Each batch is identity-tested and assayed for L-theanine content and optical purity, with testing for residual solvents, heavy metals, microbiology and finished-capsule potency.
For adults only. Consult a healthcare professional before use if pregnant, breastfeeding, using sedatives or blood-pressure medicine, or managing a medical condition. Do not drive if you experience drowsiness.
Interactions
Use caution with sedatives, blood-pressure medicines and other products intended to induce relaxation. Pregnancy and breastfeeding data are insufficient.
L-theanine is often described as non-sedating, but individual responses vary. Do not drive if drowsiness occurs.
L-theanine has been studied with caffeine, but this product contains no caffeine. Consider total caffeine intake and personal sensitivity.
It can be taken in the evening if that timing suits you. It is not intended to diagnose or treat insomnia.
Two hundred milligrams is common in human studies and allows a simple one-capsule serving.
Suntheanine® is a purified L-theanine ingredient produced through a controlled enzymatic process for consistent identity and L-isomer purity.
