Theanine Serine contains the amino acid L-theanine, to support relaxation and focused attention, and the calming neurotransmitter GABA.

I have started to take these tablets after reading reviews, mainly to help with sleep issues. I've started taking a tablet after breakfast, I was taking them in the evening before. A little early to notice results as yet.

Thanks for your feedback!
