Casein Proteins as a Vehicle to Deliver Vitamin D3: Fortification of Dairy Products with Vitamin D3 and Bioavailability of Vitamin D3 from Fortified Mozzarella Cheese Baked with Pizza

Current vitamin D intakes in Canada are inadequate. The extension of vitamin D fortification to additional foods may be an effective and appropriate strategy for increasing vitamin D intakes in the general population. Cheese is potentially an ideal candidate for vitamin D fortification. We introduce...
