It's a green tea extract standardized to 45% EGCG. The rest will be plant material and other polyphenols like epicatachin, catechin, epicatechin gallate, etc. There won't be much, if any, L-theanine in there, because the growing conditions that lead to high L-theanine levels are counterproductive to high EGCG levels. Since this extract is meant for high EGCG, it was made from green tea leaves grown and processed for that. High L-theanine in tea leave happens when you shade grow. Shade growing lowers polyphenol content. You wouldn't use shade grown leaves to make an extract for EGCG because of that.

Replying to Experienced8 · ND does it again! Would love to hear from the ND team how Coriander's relaxing effects compare to other common compounds like lemon balm or l-theanine.

It's much more effective, at least for me. We brought this out because we started working with a company in Europe that specialized in supercritical CO2 extracts, and they sent me a sample of some of their stuff. I start

It's going to depend on the person. What works best for one person might do nothing for you, or have side effects. We like to talk in generalities, but people's brain chemistries vary a lot more than most realize. So fin

It's in the capsule shell, so you can differentiate between the higher and lower doses of caffeine. Color-coding the high dose caffeine version was more of a safety consideration, so people wouldn't mix up their doses. A

L-Theanine capsules dosage too high

I don't disagree. I often find them too high for myself as well, unless I am taking a strong stimulant. This is why I more often use our 200mg caffeine/100mg L-theanine. However, that's not ideal for those that don't wan
