Includes nutrients that can help your body absorb and direct calcium where it’s needed
Our formula includes four types of calcium, each selected for its gentle, bioavailable qualities—offering a more well-rounded approach to absorption and bone support than single-source calcium supplements.
Vitamins D3 and K2 help your body absorb calcium and guide it to bones, while helping support proper calcium distribution away from soft tissues like arteries.
Vitamin C supports the body’s collagen production, while L-Lysine plays a key role in forming collagen—an essential protein that makes up the structural matrix of bones, joints, skin, and internal organs. Boron helps support calcium metabolism, and Inulin promotes gut health, which can aid in calcium absorption. Together, these nutrients offer well-rounded support for bone strength, connective tissue health, immune function, and overall vitality.
