Is this calcium, vitamin D3, K2 and B12 tablet meant to be used purely as a calcium supplement, or does it work as a general multivitamin?

Think of this one as more of a bone-health tablet than an all-purpose multivitamin. It combines calcium with vitamin D3 and K2 to help your body actually absorb and use that calcium properly, along with a bit of B12, magnesium and zinc thrown in. If you're looking for broader nutritional coverage - like B-complex vitamins or antioxidants - this wouldn't be enough on its own, so it's worth telling your doctor what you're trying to address so they can confirm if this fits your needs.
