Vitamin D is available in two forms, which are Ergocalciferol (D2) and Cholecalciferol (D3). The two forms are slightly different from each other. Both forms increase blood levels of vitamin D, and both forms provide vitamin D benefits. However, research indicates that vitamin D3 is more effective at increasing blood levels of vitamin D than vitamin D2.

In addition to vitamin D3, this supplement also contains vitamin K2 in its biologically active form, which, like calcium, supports normal bone health. Among other things, it also helps maintain normal blood clotting. Vitamin K2 in the form of MK-7 (Menachinon-7) is the most biologically active form of vitamin K2. It is common for the modern Western diet to contain a low number of fermented foods, so we also tend to have lower levels of vitamin K2.
