I'm not sure what this is supposed to to, honestly, but it's not making me sick like other magnesium has in the past. I'm taking it for dental health.

High quality supplement line

Like other tablets from Source Naturals, this Ultra-Mag can be hard to swallow. But it supplies a unique blend of minerals and seems well-balanced. Worth a try!

Good product. I think they are a trustworthy company

I use this to help me relax my muscles and I take this with a cup of coffee in the AM and helps me get "Moving" if you know what I mean. Magnesium is important and usually should be taken with calcium unless you want it for what I use it for [This review was collected as part of a promotion.]
