MDR built Day-Cal on something learned over more than thirty years in nutrition science: most calcium formulas give you calcium and stop there. Yet the skeleton remodels itself every 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 the trace minerals zinc, copper, manganese, and boron that most bone formulas leave out. Every amount is printed on the panel.

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 standardized form used in published research, for antioxidant support; Fucoidan from brown seaweed; MSM for connective tissue; and Biotin and Silica for hair, skin, and nails. No dyes, no gluten.
