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.

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.
