Will this make me sleepy?
No. L-theanine produces alpha waves — calm but fully awake. Not a sedative.
Can I take it with coffee?
Yes — it pairs well. Theanine softens the jitter, keeps the alertness.
Safe to take every day?
Yes. No tolerance, no dependence. But you don't have to — take it only the days you need.

Vegan yes (cellulose capsule). Halal certification pending.

No. L-theanine produces alpha brain waves — the state you're in when you're reading a good book or ten minutes into meditation. Calm, but fully awake. It's literally not a sedative.

No rebound, no comedown, no morning grog. L-theanine has a clean half-life — it fades out over a few hours without any dip.

Yes — it pairs well. L-theanine + caffeine is one of the most-studied combinations in the nootropic space. Caffeine gives you alertness, theanine softens the jitter and the crash.

Talk to your doctor first. L-theanine is generally well-tolerated with SSRIs in the literature, but we're not your doctor. Bring the ingredient list to your next appointment.

Yes. Neither ingredient builds tolerance, neither causes dependence, and both are on the FDA GRAS list at these doses. That said — you don't have to take it every day for it to work.

Vegan: yes (vegetable cellulose capsule). Gluten-free: yes. Halal: pending certification.

Singapore: 1–3 working days.
