I am not a medical professional.On occasion, when I have myself a coffee, this product seems to help regulate my nerves. I am very happy with the vitamin content, and find that it alleviate my jitters when combined with mild exercise. The strength is great because it isn’t too heavy of a dose, and the size of the bottle makes it easy to take on the go. Very effective, perhaps my favorite new go-to for anxiety relief (besides sun and movement)

Works to calm me down and I sleep better too. No smell or taste. Goes well if you get jitters with coffee or tea. Helps combat that. Seem like quality items. Helps my elderly mother sleep too.

I started taking L-Theanine to help with focus and stress, and I’m really impressed. It helps me stay calm and clear-headed without making me sleepy. I’ve even noticed it pairs really well with my morning coffee—no jitters, just smooth energy and focus. The capsules are easy to take and I feel the effects pretty quickly.
