It’s time to shine from the inside out. Vitamin D is nicknamed the “sunshine” vitamin, because our bodies only make it after our skin is exposed to the sun. Vitamin D aids in the absorption of calcium, helping to form and maintain healthy bones and teeth, as well as promote immune health. Country Life’s Vitamin D3 1,000 I.U. comes from lanolin, a sustainable and safe source in a base of medium chain triglycerides (MCTs).
