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
More than 100 citations support the ingredients in Osteo-K and Osteo-K Minis for bone health, cardiovascular health and cancer support.

After chemo for breast cancer in 2016 my DXA showed significant bone density loss in both femoral neck of hip and lumbar spine. My ND recommended OsteoK Minis because of the wonderful clinical data. I began taking in 2017 - by my repeat DXA in 2018 the femoral neck had "improved bone mineral density" and "stable osteoporosis of the lumbar spine." I cannot say enough about this product! Chemo for bc is harshest on post menopausal women so I guess it was no surprise that even with a lifetime of good habits I still developed it. Thanks to Oseto K Minis my hip is now considered to have "osteopenia" - great thing since we all know how precarious a hip fracture can be as we age. I will be using this product for good! Thank you Dr. Neustadt!
So excited for your results! Thank you for leaving a review.
A good product at a fair price.
Thank you for your review. We're glad you like the product and recognize the excellent value for the price.
First used it when I was disagnosed with osteopenia. It now seems to be under control, and if so, I know it's due mostly to Osteo-K. Many thanks.
Wonderful news! So glad Osteo-K Minis is helping. Thank you for leaving your review.
After using your product for just about a year my dexa scan showed : hip - left - return to normal and lower back stable. Cannot say enough about your product. Thank you.
Yay! Fantastic news. Thank you for sharing your experience so others can learn how the product may help them too. I'm so happy that you're bones are getting stronger and that Osteo-K Minis is helping you.
my averaged DEXA score improved by 1.2 in 11 months on this product with no other changes in diet, meds or workouts.
That's wonderful! So glad you've had such amazing results. Thank you for your review and sharing your experience.

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.
