Both include some similar ingredients like Melatonin, L-Theanine, GABA and 5-HTP, which help you fall asleep and improve sleep quality during the night. Combined together, these ingredients improve the depth of sleep, keeps you in REM sleep longer, and encourage Alpha brain waves during sleep (the brain waves that are most important during sleep). Whichever gummy you choose, you’ll be getting a great night’s rest with either of the products! Sleepy contains CBD and Evening Primrose Oil, while Sleepyhead is formulated without CBD and instead utilizes herbs and botanicals that calm the mind and ease anxiousness that can be a barrier to falling asleep.
