Osteo-K by NBI is a professional-grade bone health formula designed to support healthy bone mineral density, promote normal calcium utilization, and maintain healthy skeletal structure across the lifespan. This 180-capsule formula delivers a comprehensive combination of fat-soluble vitamins, bioavailable minerals, and bone matrix cofactors in clinically informed doses, formulated to support the multiple physiological pathways that determine long-term bone integrity.
Key Benefits of Bone-Supporting Vitamins, Minerals, and Structural Cofactors
- Vitamin K2 (as Menaquinone-7, MK-7): The most bioavailable and longest-acting form of Vitamin K2, supporting healthy osteocalcin carboxylation for normal calcium deposition into bone matrix and activating matrix Gla-protein (MGP) to maintain healthy calcium clearance from soft tissues and vascular walls.
- Vitamin D3 (as Cholecalciferol): Supports healthy intestinal calcium absorption, promotes normal osteoblast activity, and maintains healthy immune modulation in bone and musculoskeletal tissue.
- Vitamin K1 (as Phylloquinone): Supports healthy carboxylation of bone Gla-proteins and promotes normal coagulation factor activity, complementing K2's role in bone matrix mineralization.
- Calcium (as Calcium Citrate and Calcium Malate): Highly bioavailable organic calcium forms that support healthy bone mineral density and promote normal calcium availability for bone matrix deposition, muscle function, and nerve conduction.
- Magnesium (as Magnesium Glycinate and Magnesium Malate): Supports healthy hydroxyapatite crystal formation in bone matrix, promotes normal osteoblast and osteoclast activity, and maintains healthy muscle and nerve function essential for skeletal support.
- Zinc (as Zinc Bisglycinate): Supports healthy alkaline phosphatase activity in bone tissue, promotes normal collagen synthesis, and maintains healthy osteoblast function and bone matrix formation.
- Boron (as Boron Glycinate): Supports healthy estrogen and testosterone metabolism relevant to bone density maintenance, promotes normal magnesium and calcium utilization, and maintains healthy bone mineral density in postmenopausal and aging populations.
- Silicon (as Silicon Dioxide): Supports healthy collagen cross-linking in bone matrix and promotes normal bone mineralization and structural integrity in the early stages of bone formation.
- Strontium (as Strontium Citrate): Supports healthy bone formation activity and promotes normal osteoblast function, maintaining healthy bone mineral density as a structural trace mineral in bone tissue.
- Manganese (as Manganese Bisglycinate): An essential cofactor for glycosaminoglycan synthesis and superoxide dismutase activity, supporting healthy bone matrix formation and antioxidant defense in bone tissue.
- Copper (as Copper Bisglycinate): Supports healthy lysyl oxidase activity for collagen and elastin cross-linking, promoting normal connective tissue and bone matrix structural integrity.
- Vitamin C (as Ascorbic Acid): An essential cofactor for collagen synthesis that supports healthy bone matrix formation and promotes antioxidant defense in bone and connective tissues.
- Vitamin B6 (as Pyridoxal-5-Phosphate): Supports healthy homocysteine metabolism, promoting normal collagen cross-linking in bone matrix and maintaining healthy bone structural integrity.
- Folate (as Methylfolate): Supports healthy methylation pathways that regulate homocysteine levels, promoting normal bone matrix collagen integrity and healthy osteoblast function.
- Vitamin B12 (as Methylcobalamin): Supports healthy homocysteine metabolism and promotes normal osteoblast activity, maintaining healthy bone formation and normal nerve function in musculoskeletal tissue.
- Ipriflavone: A synthetic isoflavone that supports healthy osteoblast activity and promotes normal bone mineral density maintenance, particularly in individuals with declining estrogen levels.
- Phosphorus (as Calcium Phosphate): A primary structural mineral in hydroxyapatite, the mineral component of bone, supporting healthy bone density and promoting normal bone matrix mineralization.
- Vitamin A (as Beta-Carotene): Supports healthy osteoblast and osteoclast balance and promotes normal bone remodeling activity in conjunction with Vitamins D3 and K2.
Osteo-K is formulated around the clinical understanding that bone health depends on a coordinated network of vitamins, minerals, and cofactors rather than calcium alone, and that Vitamin K2 as MK-7 is the critical missing link in most standard bone support formulas. MK-7 activates osteocalcin, the protein that anchors calcium into bone matrix, and activates MGP, which directs calcium away from arterial walls and soft tissues, addressing both the bone deposition and the vascular protection dimensions of calcium metabolism simultaneously. By combining MK-7 with highly bioavailable mineral forms including Calcium Citrate, Magnesium Glycinate, and chelated trace minerals, alongside homocysteine-lowering B vitamins and bone matrix structural cofactors, Osteo-K provides a comprehensive and clinically informed approach to bone density maintenance that isolated calcium or vitamin D supplements cannot replicate.

Frequently Asked Questions
What is Osteo-K used for?
Osteo-K is a comprehensive bone health formula designed to support healthy bone mineral density, promote normal calcium utilization, and maintain healthy skeletal structure. It is intended for adults seeking evidence-informed nutritional support for long-term bone health maintenance, particularly those with increased bone density concerns related to aging, hormonal changes, or dietary insufficiency.
How do I take Osteo-K?
The recommended use is 3 capsules twice per day, or as directed by a qualified healthcare practitioner. Because Vitamins D3, K1, K2, and A are fat-soluble, this product is best taken with meals containing dietary fat to support optimal absorption.
Why does Osteo-K include Vitamin K2 alongside Vitamin D3?
Vitamin D3 promotes calcium absorption from the digestive tract, but without adequate Vitamin K2, that calcium may not be efficiently directed into bone tissue. K2 as MK-7 activates osteocalcin, which anchors calcium into bone matrix, and activates MGP, which supports healthy calcium clearance from soft tissues. This combination addresses both the absorption and the routing of calcium, which is why many integrative practitioners consider K2 an essential companion to D3 in bone support protocols.
Is Osteo-K safe to take with anticoagulant medications such as warfarin?
Vitamin K1 and K2 can interact with warfarin and other vitamin K-dependent anticoagulants by affecting clotting factor activity. Individuals taking warfarin or other anticoagulant medications should not use this product without first consulting their healthcare provider and having their INR monitored. Do not adjust or discontinue anticoagulant medications without medical supervision.
How long does it take to see results from bone support supplementation?
Bone remodeling is a slow process, and meaningful changes in bone mineral density are typically assessed over 12 to 24 months of consistent supplementation alongside adequate dietary calcium, weight-bearing exercise, and appropriate medical monitoring. Bone density testing (DEXA scan) is the standard clinical tool for tracking changes over time. Consult your healthcare provider for appropriate monitoring based on your individual bone health status.
Is Osteo-K suitable for postmenopausal women?
This formula includes Ipriflavone, a synthetic isoflavone that has been studied specifically for its role in supporting healthy bone mineral density in postmenopausal women. The inclusion of MK-7, Vitamin D3, and bioavailable minerals makes this formula well suited for individuals with increased bone density concerns related to hormonal changes. Consult your healthcare provider to determine whether this formula is appropriate for your individual health status and medication regimen.
