Good quality but subtracting for price.

This is a more expensive version of L-Theanine without being significantly higher quality. Yes this brand is consistently high quality and this product is no exception, several other brands match it for L-Theanine at a lower price. You can pay the loyalty tax if you don't want to research and you'll be fine. But there are better options.

Perfect quality

I’ve been using Pure Encapsulations L-Theanine for a few weeks now, and I’m really impressed. Each capsule contains 200 mg of Suntheanine®, a clinically researched form of L-Theanine known for promoting relaxation without causing drowsiness. I take one capsule in the evening, and it helps me unwind and sleep more soundly. The capsules are easy to swallow, and I appreciate that they’re made with hypoallergenic, vegan ingredients, free from gluten, GMOs, and unnecessary additives. Overall, it’s a high-quality supplement that delivers on its promises.

Reliable product

What’s written on the bottle is actually what’s inside. I use this to counteract the jitters from drinking lots of coffee. It really helps
