Dietary supplement from Dr. Jacob's in the form of drops, containing vitamins D3 and K2 MK-7. Vitamin D3 Dr. Jacob's is obtained from sheep wool lanolin (extracted using UV irradiation). Vitamin K2 Dr. Jacob's is special because we get it from essential oils. This ensures the highest amount of pure menaquinone-7 (MK-7), its excellent bioavailability and bioactivity, and the absence of GMO contamination.
