40% of the population is vitamin D deficient. Enzymedica's Vitamin D3 includes Vitamin K2, shiitake mushrooms, and inulin for three benefits in one! Vitamin D3, or cholecalciferol, is essential for multiple health benefits, including strong bones and strong immune and cardiovascular systems. Enzymedica's Made with Organic D3 supplement uses the preferred form of Vitamin D, D3, which is algae derived and organic. While most vitamin D3 comes from lanolin (sheep's wool), the D3 found in Enzymedica's Made with Organic D3 + Vitamin K2 comes from sustainably sourced and organic algae. The benefit of using organic D3 is that it is purer and does not contain harsh chemicals that are used in conventional harvesting methods. Enzymedica's Made with Organic D3 + K2 formula provides 5,000 IU of vitamin D3 and 90 mcg of vitamin K2 to supplement immune and bone health. When combined with vitamin D3, this soy-free K2, K2VITAL supplements the proper transportation and absorption of calcium into the body. Like vitamin D3, vitamin K2 is an essential vitamin, meaning the body cannot make it, so it must be obtained through diet or supplements.
