been taking this supplement for several months. Improvement in sleep quality and wakefulness was pretty noticeable on the second day. Had no idea how 'brain-fogged' I felt prior to taking it. It seemed to help recovery time with respect to exercise and I overcame some plateaus while taking it. Another fringe benefit I've noticed is that hangovers from drinking are non-existent. Would definitely recommend trying it, but your mileage may vary.

Chromadex also sells the same supplement but I do not know of any differences between what they provide and what Elysium provides.
