It’s time to shine from the inside out. Vitamin D3 is nicknamed the "sunshine" vitamin because our body makes it only after our skin is exposed to the sun. Most people don’t get enough sunlight to produce an efficient amount. Vitamin D aids in the absorption of calcium, helping to form and to maintain healthy bones and teeth, as well as promote immune health. Country Life’s Vitamin D3 comes from lanolin, a sustainable and safe source in a base of medium chain triglycerides (MCTs).
