Works great!
Size: 180 Count (Pack of 1)
Purchased this item at the recommendation of my PCP to help alleviate my Charlie Horses in my legs. Take 3 tabs an hour or so before bedtime, and it solved that issue.

It's easy to take one pill a day.
Size: 180 Count (Pack of 1)
I sometimes get cramps in my calves while sleeping, so I eat before bed. Personally, I think it's effective. I am satisfied with the product and delivery.

Reliable Overnight Protection for Peaceful Sleep
Size: Size 3, Unit Count: 132
They provide excellent overnight protection and keep my baby dry through the night, which means fewer wake-ups and better sleep for everyone. The fit is snug but comfortable, and the waistband helps prevent leaks even with lots of movement. They’re soft, absorbent, and do exactly what they’re designed to do. A great choice for parents looking for dependable overnight diapers.
