L-theanine vs D-theanine

Original post in this thread

intern6 · 4 points

Years ago I bought L-Theanine from one of the more trusted bulk suppliers.

Even now, still having the powder (I assume it is still good, no reason to think otherwise) and I get no benefit whatsoever, probably even the opposite of the assumed effects.

On the other hand, I previously tried L-theanine from Suntheanine and actually had some good results.

They claim that it is hard (or was at the time) to purify only the L-isomer alone, without the d-isomer. They also claim that the d-isomer can block the l-isomer absorption. And that is is also hard to distinguish between the two when testing the end product for purity. Perhaps nowadays the situation is different, but I somewhat believe that low-end suppliers might still sell non-L-isomer products unintentionally (assuming the whole issue is/was real)

What is NDs stance about the issue?

\* I do believe you actually sell the L-isomer, but perhaps you could elaborate/debunk the idea.

Jesus, dude... Google shit before you do stuff like this. You cannot use test strips to test for heavy metals content in supplements. They shouldn't even be used to test for heavy metals in water, or anything you are con

⚠️ NEW PRODUCTS ALERT | Resveratrol Capsules, & Supercritical C02 Coriander Capsules & Solution⚠️

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

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
