Menaquinone-7 is the active trans-isomer of natural Vitamin K2 with the highest bioavailability and longest half-life in the blood. It is a powerful cofactor in transporting excess Calcium out of the arteries and depositing it into the bones. Red Algae Calcium (Algas Calcareas) is a plant-based natural Calcium which is derived from marine algae. The algae predigests the Calcium and minerals found in it, thus the Calcium is easily broken down to be absorbed in the human body. Vitamin D 3 helps in the absorption of Calcium from the gastrointestinal tract and helps to maintain Calcium balance in the body. The combination of Red Algae Calcium with Menaquinone-7, Vitamin D 3 and trace minerals can play a vital role in formation and maintaining healthy bone and teeth in children, disorder of osteogenesis, latent tetany, hypoparathyroidism, and pancreatitis.
