Großartig!
Verified purchase
I am very satisfied with this L-Theanine supplement. I noticed a real difference after using it — I feel calmer, more relaxed, and at the same time I can stay focused and concentrated. It helps me handle daily stress better without making me feel sleepy or tired. The capsules are easy to take and the quality seems excellent. I will definitely continue using it.

L-theanine is a naturally occurring amino acid commonly found in tea leaves, particularly green tea. It’s widely known for promoting relaxation and calmness without making you feel sleepy. L-theanine may help support mood and stress balance by influencing neurotransmitters like serotonin, dopamine, and GABA. It’s often combined with ingredients such as melatonin to help ease anxiety, enhance focus, and support better sleep quality.

A generous amount of theanine; 200 tablets will last a long time, and it works well with caffeine.

⭐⭐⭐⭐⭐ Excellent L-Theanine at a super price!
Verified purchase
I bought Type Zero Clean L-Theanine 200 mg, 200 capsules. This is my second bottle, and I really like it. What I like: The pure ingredients are free of unnecessary chemicals (Type Zero positions itself as "clean"—no sugar or artificial additives). Convenient dosage—200 mg per capsule. You can take one per day or as needed. The large package (200 capsules) lasts a very long time, making it a great value. It helps with anxiety and stress—it's calming without making you drowsy during the day. It pairs well with coffee/caffeine: it eliminates nervousness and jitters, and my focus becomes more balanced and calm. My sleep has become deeper and better quality if I take it in the evening. The capsules are small, easy to swallow, and have no smell or taste. Cons: The effect varies from person to person. I notice a noticeable benefit, but there may be a slight adjustment during the first few days. Conclusion: One of the best L-Theanine options on iHerb for price, quality, and quantity. If you're looking for a pure supplement for calmness, focus, or better sleep, I recommend it. I'm happy and will be ordering more! 5/5 💊

Super cost-effective
Verified purchase
200mg in 200 capsules for this price?! The capsules aren't made from plants but from gelatin, so I guess that's where they're cutting costs? This manufacturer is relatively new, so I don't know about their reliability, but judging from the data they've presented, it seems quite impressive.

The product is excellent; the manufacturing quality is superb, and the ingredients are clean and pure, as expected from this company. The quantity is very generous (200 capsules) and will last a long time, making the price economical and excellent. It noticeably helps with relaxation and calmness without causing drowsiness. I highly recommend it.

For the elderly, L-theanine is said to be very compatible with "maintaining cognitive function" and "improving sleep and lifestyle-related diseases," and is expected to have significant benefits in improving QOL (quality of life), so my parents are taking it!
