Orexin A and Orexin B

THE WAKEFULNESS PROMOTER

Hypocretins

Orexins are neuropeptides produced in your hypothalamus that control wakefulness, hunger, and stress responses. Orexin deficiency causes narcolepsy. That's how important they are for staying awake and alert. Supplementing with orexins can boost daytime alertness, regulate appetite, and help normalize disrupted sleep-wake cycles.
