Great addition to my routine for restful night

This is a real great supplement. It had a very mild taste. But for sure helps with the sleep. You wake up rested and energized. Love this product. Mild smell.

Good magnesium powder with L-teanine Tart cherry. I suffer from stress and have trouble sleeping, but this helps me relax and sleep better. It gastes good, mixes easly, and is a convenient option for rest.

Decent powder

I really like the flavor of this product. It's light and not overly sweet. It mixes really well too. I gave it three stars because I didnt notice a difference in sleep but I do enjoy it as a tasty beverage before bed in my bedtime routine.

Deep sleep

I love that you can put this in sparkling water as well as any beverage for that matter. Just a single scoop can do a world difference for deep sleep and rest.
