Shine from the inside out with a healthy dose of the one and only “sunshine” vitamin. Vitamin D is an essential but oftentimes elusive vitamin that our bodies only make after our skin is exposed to the sun. Unfortunately, most people don’t get enough sunlight to produce a sufficient amount of vitamin D for optimal nutrition. Vitamin D aids in the absorption of calcium, helping to form and maintain healthy bones and teeth. Vitamin D also supports colon and immune health. The Vitamin D3 5,000 I.U. found in this formula comes from lanolin, a sustainable and safe source in a base of medium chain triglycerides (MCTs). Also available in 1000 I.U., 2500 I.U. and 10,000 I.U. strengths.
