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 document more than 7,000 people (view tables 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.
180 capsules per bottle, a 30-day supply

Since I have been taking osteo- k my bone density scans have remained stable. My mother suffered dramatically and I’m hoping to prevent that.
Thank you for your review. I'm sorry your mother struggled with osteoporosis and I'm glad you found Osteo-K to help you support your bones.
I have three clients who test extremely well on this product and repeat orders consistently. Bone numbers continually test well.
I'm glad your clients are getting great results with Osteo-K. Thank you for leaving a review.
I had my full DEXA this week. Now, only L-1 is osteoporosis, L 2 is osteopenia and L-3/4 are normal! Two years ago, before Osteo-K, all 4 were osteoporosis. My labs were good, too. Bone production is up; resorption is down. So taking this wonderful supplement, watching the diet and exercising really can alter your results. The doctor used to push the pharmaceutical poisons on me but didn’t even mention them this time. That is the best accomplishment! I will never stop taking Osteo-K!
What wonderful news!!! Thank you for sharing your experience.
My wife and I have been using this product for several years. We both have bone issues. My wife chose this product rather than take IV Bisphosphenates. No side effects. No issues with bones either. Recommended!
Thank you for your review.
I have been a fan of Osteo-K for some time now and do not want to ever run out. My bone health is paramount to cruising through years to come. I am 70 yrs. young. I will continue to use this product and impressed by the research that went into it.
I've been using Osteo_K for over 9 years. I was first told about yur product from a physical therapist and a chiropractor. This was after, I broke my pelvis from an insufficiency fracture. I have fallen several different times,but the only broken bones I have experienced have been an ankle and a rib. I have been experiecning smaller strokes. I am so glad that I take Osteo-K instead of a bizphosphenate. I have never used any other bone-strengthening med except Calcium 1200mg Daily and Vitamin D3 5,200 miu daily. Suzanne Kacmarcik
Thank you for leaving your review of Osteo-K. We love that it's helped you so much.
I have been taking osteoK since I think 2011. My bone density has improved at every scan. I actually went from osteoporosis to osteopenia in my hip.
What fantastic results! So happy Osteo-K is part of your approach to improving your bone health. Thank you for leaving a review.
I have been using Osteo-K for many years. It works so well that I shared it with my mother who no longer broke bones when she stubbed her toes. I give Osteo-K as gifts to friends who talk about needing help preventing bone loss. Over the past 10 years, my bone density has declined only a fraction and my physicians were amazed. They thought I would be in a wheel chair by now. I am so grateful for Dr. Neustadt and this great product.
Your review is why we do what we do. We're glad that we could be part of helping you, and your mother, with your health. Thank you for sharing your experience.
Love taking my Osteo-K. This product has been one that I've taken for several years now. It helps keep my bones strong and guards against signs of arthritis in the joints. Before I started taking the Osteo-K, I was having stiffness and slight pain in my wrists but notice that all went away after taking this product. I'm turning 65 in June and I feel great! Suggest Osteo-K be taken with Vitamin D3. If taken daily, especially during the cold seasons, the do wonders to your body. The delivery of this product is always right on time.
Thank you for giving Osteo-K a review. I'm thrilled to read that Osteo-K is helping you and that you're also happy with our shipping.
I've been using Osteo-K for over 10 years. Ibeleive it has grown my bones back - better than Boniva, which I used for 5 years, before fracturing my pelvis.
