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.

best sleep aid I have found
Item Package Quantity: 1, Style: 240 Count (Pack of 1)
this is the best sleep aid I have found. This dissolves under the tongue, goes right into your system and I take two of them every night. They do not work like a sleeping pill and knock you out immediately--- they are natural and take longer plus I feel you need time to get them in your system and feel a difference. Therefore I did not expect immediate results. I have had insomnia for years so I took them for a couple of months when I started noticing the most effect. Now when I take them and let them dissolve under my tongue I know that in about 30 minutes or less I will start to feel drowsy and will naturally go to sleep. Over time I have felt my sleep has deepened and now I rarely awaken during the night. By the way, in the beginning of my search to solve my insomnia problem, I tried taking the melatonin pills that you just swallow but did not get the same results that I have gotten with these that I put under my tongue. Excellent company and excellent product.
