MDR built Day-Cal on a belief earned over more than thirty years in nutrition science: not all calcium formulas are created equal. Most give you calcium and stop there — yet the skeleton remodels itself every single day, and that work draws on far more than one mineral. So we surrounded 500 mg of calcium with the partners it depends on: magnesium, phosphorus, Vitamin D3, and a quiet cast of trace minerals — zinc, copper, manganese, and boron — that most bone formulas quietly leave out. Every amount is printed right on the panel, because the formula is the whole point.

Then we went further. Day-Cal uses K2VITAL® MK-7, the most active form of Vitamin K2, derived from algae — the nutrient that helps direct calcium toward bones and teeth, where the body wants it. We added the ingredients you almost never find in a calcium product: resVida® Resveratrol, the premium standardized form Harvard researchers made famous, for antioxidant support; Fucoidan from brown seaweed; MSM for connective tissue; and Biotin and Silica for hair, skin, and nails. No dyes, no gluten.
