I started taking this for sleep since I'm hitting menopause and it's my biggest issue. It's helped immensely. I'll be reordering regularly.

This is an excellent source of magnesium! I am stocking up!
By Ginny
I bought the Magnesium, and take two tablets before bed each night and sleep like a baby. It’s too subjective for me to rate anything else, but my doctor just told me yesterday that I need to take magnesium as a daily routine and I was happy to tell him that I was taking a really good one.

The service is great. Plenty of communication throughout the process.

I really enjoy the product. The customer service has been great. I haven’t been able to find other magnesium supplements that have the specific magnesium’s in it. So I’m happy that I found this and it’s available to me.
