This Country Life Calcium Magnesium Potassium is a good deal because it is very cheap and you get 180 pills in one container. If you are older this is definitely something you should be looking into taking. As we age, our bones become more brittle. Exercise will help in bone health, but a supplement like this one may help to fill in the gaps where your nutrition is lacking.

Ordered the product to help relieve reoccurring lower back spasms and cramping. Felt like a charlie horse like you get at night in your legs. I have been taking the product for 3 months and had no reoccurences.
