It works great

After 45 mins, I can start to feel the calming effects. But this is a natural supplement, don't expect it to be as potent as Xanax. The effect is mild but noticeable. Helped me calm my driving anxiety without inducing sleepiness. Doesn't have any taste and the tablets are firm and not powdery. Good quality

Excellent!

It's the only product that we could find as a tablet which is great as it's for our daughter (as per Naturopathic doctor recommendation) and being a tablet it can be cut in half easily as opposed to capsule. The package and quality is superb. We really see a difference in our daughter's focus and agitation. Recommended.

Excellent!

I take one of these in the morning and one in the evening and I definitely notice a mild calming effect. The product contains Suntheanine®, which is a a high purity (concentrated) form of theanine, which instantly makes it a standout in terms of the quality of the ingredient.
