Hi, Patsie! Well, the supplements I take are from Puritan.com and they contain both the malic acid and magnesium. Those didn't cause diarrhea with me but I did start out slowly. You probably won't see a lot of difference until you get to the 2,400 range of malic acid. So, be patient. Reread the thread I wrote about it on the Fibro 101 thread and that might help you.
Now, are you getting potassium in your system? Tea, potatoes, and bananas have a lot of potassium in them Lack of potassium can cause cramping too.
Lastly, are you taking a calcium with D supplements along with the malic acid/magnesium supplement? You need to do this to balance things out. I mentioned that in the thread about it. Also, I was diagnosed with osteoporosis a couple of years ago. I upped my calcium to 1,200 mg with D and you know what? Once I did that, my leg and foot cramping stopped! I checked and a lack of calcium can also cause cramping! I didn't know it at the time.
I know how painful the cramping can be. I used to have my feet cramp up at night and I would have to jump out of bed and stand up to help stop the cramping. Sometimes I had to walk around for a while. But all of that stopped when I started taking more calcium.
I'm not sure how old you are but if you are over 50 you do need 1,200 mg of calcium with D to help prevent osteoporosis. I take Citracal because it is the easiest to be absorbed. Hope this help you. Let me know how it goes!
