I get foot cramps also...there's a big difference between the twisting restless feeling of needing l-dopa supplementation and a real foot cramp (where the toes curl up or down, the pain is terrific and you have to get out of bed and try to walk to get it to go away) When that happens to me , I know I am short on minerals and take a dose of Now Coloidal Minerals right then and another dose in the daytime. That usually is enough to alleiviate them for a couple of weeks. I have used this for years and my father , who is 85 yrs young does too. Don't know what I'd do without the stuff!
