Superior Quality & Effective
Size: 90 Count (Pack of 1)
Thorne Magnesium is a total game changer! The quality is exceptional, and it has finally helped me get the restful sleep I've been missing. I’ve struggled with insomnia and tried numerous other brands to no avail, but Thorne is truly superior. It is absolutely worth the investment for results that actually work.

Reliable

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.
