Yes, I have been very happy with Trace Minerals. We take Trace Minerals magnesium. It completely stopped my husband's restless legs symptoms. Other magnesium supplements didn't help so we believe Trace minerals is well absorbed by him.
If you'd like to explore ionic magnesium, I can also recommend ReMag. It's about $30 for a 90 day supply. Dr Carolyn Dean also has a product called Remyte that works well with ReMag for overall blah feeling.
