I use Source Naturals Magnesium Malate CAPSULES (625 mg). I feel that tablets, especially extended-release tablets, don't dissolve completely. I take 3 capsules, 3 times a day.

I am almost pain free now. Was having excruciating leg pain.

I take a 1000 iu softgel of vitamin D3 every 12 hours also.

My insomnia has gotten better too.
