When you train hard and exercise regularly, you know how important it is to recover. In fact, recovery is when gains are made from the overload of training. Relaxation is key to enhanced athletic performance. In clinical studies, L-theanine reproduced the positive effects of tea without any of the stimulant effect connected with caffeinated drinks and we choose to use clinical-grade L-theanine which is not known to be addictive and will not cause drowsiness. Each tablet provides 200mg of L-theanine per tablet. We use a pure pharmaceutical grade L-theanine, made in the UK to the highest standards.
