I take my CalMagPlus every day and more when I get cramps in my muscles/toes and it takes them away quite quickly! CalMagPlus is just a powdered calcium/magnesium/potassium/vit D mix that you dissolve in warm water and kick back! Mineralized salt such as sea salt and/or himalayan salt works terrific too! Helps the body hold water in the cells and if you stay hydrated you're less likely to have muscle cramps.
