Get an RBC magnesium test if you can. Without one, start with 300-400 mg daily, some at night for sleep. More than 1,000 mg tends to cause diarrhea, which tells you to back off.

Type of magnesium and dosage, please. This really depends on what you need. In a perfect world, what you would do, Lori, is you would get an RBC for red blood cell magnesium, not a straight blood test, but the red blood cell test for magnesium. See how much you need. In absence of that, what I start people with is about 300 to 400 milligrams, with some of it at night because it can help you sleep. I like to take it, I put it in my creatine HCL product because it can help regenerate ATP. It helps you work out harder, recover better, but see how you do. Some people feel great using 1,000 milligrams of magnesium a day. Some people need another 300. And I find you kind of feel it. If you go overboard, your body will tell you and you will get diarrhea and you back off. But if you really want to know, then you can test, not guess.
