Emulsi-D3 Synergy™ is a concentrated, highly bioavailable liquid vitamin D formulation offering 50 mcg (2000 IU) per 1 mL (one full dropper), along with 200 mcg of vitamin K1 and 40 mcg of vitamin K2. This is a convenient, pleasant-tasting, and easily mixable formula. Vitamins D and K are essential for bone and arterial health, and for a healthy immune function. Vitamins K1 and K2 support the normal deposition of calcium into the bone instead of soft tissue, such as the arterys and kidneys.
