The Magnesium I had not been satisfied with has magnesium oxide 400mg as it's main ingredient. Other ingredients: medium chain triglycerides, gelatin glycerin, rape seed lecithin. I have had no success in shaking the stiff muscle pain over the past year. I felt like my muscles weren't repairing themselves after exercise.

The magnesium I am taking now has magnesium 225mg (with a daily dose of 450mg) magnesium citrate, magnesium glycinate and magnesium malate, zinc, zinc citrate and zinc ascorbate, vitamin D3. Within in one week my muscle pain and stiffness had lessened considerably and my energy and enthusiasm levels improved. I am able to climb stairs in the normal way and can walk upright.

I may be misjudging product 1 and although not listed may contain exactly the same elements as product 2, but after 3 1/2 years I feel so much better after a couple of weeks of taking product 2 and feel like I am ready to start to reduce my prednisone.
