Not sure what all to say - it's a vitamin. These are the amount in milligrams that I need, and I take 1 twice a day, for the total amount my Dr. wants me to take. I like that there are so many in the bottle so I don't have to buy them so frequently. The capsules are pretty big, but I find they are not hard to swallow.
I prefer capsules to pills and thus Ca/Mg formulation is part of my night-time supplementation along with melatonin and CBD oil. It feels as if this combination supports my sleep and THAT is important. It's hard to judge the quality, but muscle testing reveals that this formulation is what my body wants.
I have dealt with severe leg pain so far my baby has been born. Doctors suggested doing something with my loosening joints and my flat feet prolapsing. Despite this, I tried a lot of things to make it easier, but accidentally discovered that as soon as I started this supplement, my pain was reduced by about 80%.
