Beneficial Sleep Benefits
Size: 90 Count (Pack of 1)
I have just started taking this item and it seems to work. My sleep is better, deeper and I awaken feeling rested. I strongly hope that this item will continue giving me great sleep results! The Magnesium is very beneficial too. I would recommend this supplement! I will purchase again provided it keeps working!!

Reliable
Size: 90 Count (Pack of 1)
The brand has a good reputation. I prefer to order products with the Thorne brand than others, because of its reputation.
The magnesium by Thorne is well worth the price. It is reputable and for sleep it works well. Other health benefits are included so not just for sleep but overall health. Good product.

Great brand great quality
Size: 90 Count (Pack of 1)
I bought this supplement during my pregnancy and absolutely love the quality of Thor supplements. It mainly contains magnesium and I highly recommend this brand. They use the purest ingredients and the effects are truly impressive. Since magnesium can cause side effects I was pleased to find this one didn’t have any for me.
