User Opinions

A consumer from Michigan who had anxiety problems for about 10 years now. He has usual feeling anxiousness for no apparent reason, panic attacks, feeling completely uncomfortable when doing ‘normal’ things like going out to dinner or to the movies. Xanax works but he said it is very addictive and unnatural and leaves me with some side-effects like feeling spaced out and drowsy. He finally took the correct dose of Theanine Serene instead and felt good.He was amazed to see his heart rate was 65 using a heart rate monitor.The way Theanine works to relax your mind is by stimulating alpha brainwaves, the state of mind achieved through relaxation and meditation that brings a person to a calm but clear headed mental state. Finally, he believes that the magnesium in this product help with depression, and the manufacturers of this product state that it helps to relax nerves and muscles.

Some consumers suggest that this product is best taken at bedtime since it can cause grogginess. However, some folks report the opposite reaction, feelings of energy and improved attention. Consumers reported a significant improvement in feelings of panic and severe anxiety in only 3 days. Ingredients list includes Sorbitol, which is a sugar substitute relative to Aspartame. We know the negative side effects to that.
