To meet the unique nutritional needs of different people, NBI has created two versions of Osteo-K, the original Osteo-K® formula and Osteo-K Minis. If you're not sure which product is right for you, click here.
Osteo-K contains a 45 mg of MK4®, also called menaquinone-4 and menatetrenone, calcium and vitamin D. MK4 is a form of natural Vitamin K2. As a nutrient, MK4 has many positive effects on the body. Research on MK4 (45 mg/day) show that it builds stronger bones and promotes healthy blood production in people with myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML).
Bone Support and Fracture Reduction: The Archives of Internal Medicine confirms that 45 mg of MK4 daily can decrease the risk of vertebral fractures by 60%, hip fractures by 71% and all nonvertebral fractures by 81% (Cockayne S et al. Arch Intern Med. 2006;166(12):1256-1261).
Cancer Support: The US FDA reviewed the research on MK4 (45 mg/day) for people with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). The FDA concluded that MK4 has the potential to treat these diseases, and awarded Dr. Neustadt’s company, NBI Pharmaceuticals, Inc. Orphan Drug Designation for MK4 for AML and MDS. As a dietary supplement, MK4 is not approved as a medication to diagnose, treat, prevent or cure any disease, but it can be taken as a dietary supplement to support healthy cell function.
SAFETY: Clinical trials published in medical journals has documented more than 7,000 people (view table summarizing these studies) taking 45 mg daily (and higher doses) of MK4 for up to eight years without any serious side effects. The US Institutes of Medicine (IOM) states that natural vitamin K, which includes MK4, has no known “tolerable upper limit,” which means it’s considered safe even in doses much higher than that found in Osteo-K and Osteo-K Minis.
CAUTION: People taking the anticoagulant medication warfarin (Coumadin) should not take this product since vitamin K interferes with this medication.
Directions: Take two capsules twice daily with food.
120 capsules per bottle, a 30-day supply

These are easy to swallow and have the right ingredients to foster bone health. I had been using them in the past but switched to another brand. I came back to this brand since I think they are better quality and have the best mix of ingredients.
So glad you love the product and have come back to NBI. We work hard to ensure our product are formulated and manufactured to the highest standards. Thank you for choosing NBI and being our customer.

Taking Osteo-K helped reverse my osteoporosis
These are fantastic results! We're thrilled Osteo-K helped you. Thank you for writing a review and sharing your experience.
Osteo K minis Great product. My hip osteoporosis improved to normal and back has remained stable. All this post chemo and steroids that ate away bones!
I'm thrilled that Osteo-K Minis has been so helpful! The treatments you mentioned are known causes of osteoporosis, but fortunately there are ways to improve bone strength and reduce fracture risk. Stories like yours are what get us excited to keep doing what we're doing to reach and help more people. Thank you for taking your time to give us such a great review. Best, Dr. John Neustadt Founder and President, NBI
Fast delivery. Total faith in product and it’s osteoperosis prevention power.
Melanie, we love getting reviews like yours and knowing how much Osteo-K Minis is helping people. It's what drives us everyday to continue to deliver innovative products and information. I'm not sure you meant your comment this way, but the FDA defines the word "prevention" very specifically. Osteo-K Minis has not been approved by the FDA to prevent any disease. The word "prevention" is reserved by the FDA for FDA-approved medications, and Osteo-K Minis is a dietary supplement. With more than 25 clinical trials on the ingredients in Osteo-K Minis, however, the research is clear that its nutrients grow stronger bones.
Great. I have been using this product for about 2 years and am satisfied with the maintenance of stabilizing bone density.
