Query: Good product!

I've purchased both the magnesium only and the magnesium with calcium. My daughter and I have fibromyalgia and my husband has Restless Legs Syndrome. Apparently men aren't supposed to take calcium supplements because of potential issues with heart rhythm so I bought this calcium-free product for my husband. He's tried many things for the RLS and no one treatment works 100%. The combination of maintaining a very consistent sleep/wake times, turning all electronics off an hour before regular bedtime, 30-60 minutes of exercise most days, no or very limited alcohol, magnesium supplements, and a small dose of prescription medication works the best for him. The powdered forms of magnesium are easier for me to digest than the hard tablets. I still need to go easy on these products and I don't take the recommended dosage of either. The magnesium really works to relax in general and help relax painful muscles. I take it at bedtime. It's fizzy and dissolves nicely.
