Review: Good product - Have been taking L Theanine, specifically this brand, for years. It works well and even my teens have started taking it as needed. They say it helps them focus on school and improves mood.
Review: Best L-Theanine for Relaxation - This is the best L-Theanine I’ve tried. It really helps relax me, especially at night. I take it with magnesium before bed and it makes me feel calm, sleepy, and ready to unwind. I’ve tried other brands, but this one works the best and feels the most consistent. It’s gentle on my stomach and helps me settle down after long, stressful days. Definitely my favorite.

## Questions & Answers

**Q: Hello. Is this 100mg?**
A: I find that the dosage should be clarified by the manufacturer. Nowhere on the bottle does it say the capsules are 100 mg but it does say serving size is 2 capsules and THAT is 200 mg. Integrative therapeutics do you care to respond????

**Q: Is this good for sleep?**
A: L-theanine is an amino acid that helps promote a restful, relaxed state without diminishing daytime alertness. During a study of human volunteers, L-theanine promoted the generation of alpha brain waves, an indication of relaxation.  Please discuss with your health care professional whether this product will be helpful for you!

**Q: is this a type of magnesium?**
A: No it an amino acid similar to tea

**Q: Is the bottle supposed to be sealed on the outside?  All mine has is the safety seal once you open the cap**
A: Mine normally has shrink wrap around the top of the bottle and then safety sealed under the top
