Build Stronger Bones from the Inside Out — Comprehensive Bone Health SupportYour bones are living, dynamic tissue that require far more than just calcium to stay strong, dense, and resilient throughout your lifetime. Jarrow Formulas Bone-Up is a scientifically advanced, multi-nutrient bone health formula that goes beyond basic calcium supplementation — delivering a comprehensive blend of bone-building vitamins, minerals, and cofactors that work synergistically to support optimal bone density, strength, and long-term skeletal health. With 120 capsules per bottle, this is serious, science-backed bone support for every stage of life.Why Jarrow Bone-Up? Microcrystalline Hydroxyapatite (MCHA) Calcium: Bone-Up features microcrystalline hydroxyapatite — the same form of calcium found naturally in human bone — which research suggests is more bioavailable and better utilized by bone tissue than conventional calcium carbonate or citrate forms. Vitamin D3 for Calcium Absorption: Vitamin D3 is essential for calcium absorption in the gut and proper calcium utilization in bone tissue — without adequate D3, even the best calcium supplement cannot reach its full potential. Vitamin K2 (MK-7) for Bone Mineralization: Vitamin K2 in the highly bioavailable MK-7 form activates osteocalcin — the protein that binds calcium to bone matrix — directing calcium into bones where it belongs and away from arteries where it can cause harm. Magnesium for Bone Structure & Density: Magnesium is a critical cofactor in bone formation, supporting the structural integrity of bone crystal and activating vitamin D — making it an indispensable part of any comprehensive bone health formula. Boron & Trace Minerals: Boron and other trace minerals support bone metabolism, enhance the effects of vitamin D and estrogen on bone tissue, and contribute to overall skeletal strength and resilience. Collagen Support: Bone-Up includes nutrients that support collagen synthesis — the protein framework that gives bone its flexibility and fracture resistance, complementing the mineral components for truly comprehensive bone support. Ideal for All Life Stages: Especially beneficial for women approaching or in menopause, older adults, athletes, and anyone concerned about maintaining healthy bone density and reducing fracture risk.
