Strong Bones helps you build and maintain stronger bones. Strong Bones contains the proper form of calcium (MCHA) from New Zealand, with cofactors for immediate absorption for the prevention of osteoporosis. Strong Bones is a broad-spectrum formula to defend against ostoeporosis. The strength of Strong Bones begins with microcrystalline hydroxyapatite (MCHA), the most readily available form of calcium for human supplementation, which is also rich in proteins and phosphorus. This is the same type of calcium found in humans. Our MCHA is sourced from pasture-fed New Zealand bovine, certified free from antibiotics, herbicides, pesticides, and Mad Cow Disease. It is freeze-dried to offer the highest quality possible.
