If you do some research on L-Theanine, you’ll find clinical research that shows L-Theanine does, in fact, assist in the treatment of symptoms that accompany anxiety and stress on a daily basis.

If these facts are true, then this product could fall short of your expectations.


New Beginnings Nutritionals advertises their L-Theanine product for $19.00 for a bottle of 60 vegetarian capsules. Consumers should shop around because there are several products that are comparable to this one but with a much lower price tag. Why pay a higher inflated price for the exact same item. In fact, there were numerous competitors that actually offered a higher milligram capsule but at a cheaper cost.

What to Expect
