The high quality of MCHA calcium and MK-7 Vitamin K2, combined with D3, calcium ascorbate, and chelated trace minerals plus potassium, provides a very strong nutrient profile, despite the magnesium oxide form.
This Jarrow Formulas BoneUp in a larger quantity offers the same advanced formula designed for comprehensive bone health. It primarily uses Microcrystalline Hydroxyapatite (MCHA), a superior calcium source that naturally includes phosphorus and other vital bone components. This natural matrix can be more effectively utilized by the body for bone building and density maintenance.
The product is further enhanced with synergistic nutrients like Vitamin D3 and Vitamin K2 (Menaquinone-7), which are crucial for calcium absorption and proper bone mineralization. It also delivers a full spectrum of trace minerals, including an optimal dose of magnesium, along with zinc, copper, manganese, boron, and potassium, all playing essential roles in maintaining skeletal strength and overall mineral balance. This larger bottle is practical for those committed to ongoing bone support.
