I swim for exercise. I usually swim 3/4 mile, and I do this several times a week, and have been into this routine for decades. One chronic problem I'd been experiencing is, about half way through my swim I would begin to get slammed with painful cramps in the arches of my feet. I never understood what was causing this problem. But just last year I started experimenting with taking magnesium and potassium supplements, and my foot cramp problem went away and has not returned. I actually tried several different types of magnesium before I finally hit on one that works for me. With dinner I take 400mg of magnesium citrate, and 99mg of potassium chelate.
