To meet the unique nutritional needs of different people, NBI has created two versions of Osteo-K, the original Osteo-K® formula for those who need more calcium and Osteo-K Minis for those who require less calcium from a dietary supplement. If you're not sure which product is right for you, click here.
Osteo-K delivers 45 mg of MK4® (menaquinone-4) per day in divided doses to more closely match the clinical trials, plus calcium (1000 mg/day) and vitamin D (2000 IU/day).
NBI's MK4 is a natural form of vitamin K2 derived from Orange Jasmine (Murraya paniculata), leaf geraniol extract. As a nutrient, MK4 has many positive effects on the body. Research on MK4 (45 mg/day taken in divided doses) 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: Two meta-analyses of clinical trials on MK4 in people with osteoporosis concluded that MK4 (45 mg/day) reduces fracture risk. One of the studies determined that MK4 (45 mg daily) can decrease the risk of vertebral fractures by 60% and all nonvertebral fractures by 76% (Cockayne S et al. Arch Intern Med. 2006;166(12):1256-1261).
A more recent study published in 2015 that evaluated 19 randomized, controlled clinical trials involving 6,759 volunteers reached the same conclusion that MK4 (45 mg/day) can reduce fractures in women with osteoporosis (Huang ZB et al. Osteoporosis International. 2015;26(3):1175-1186).
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 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

I’ve had osteoporosis for at least 5 years. The numbers for my spine have been worsening with each Dexa. Until my last one. After taking Osteo-K minis for only 5 months, my numbers Greatly improved on my recent Dexa. Great news. This is the only supplement my doctor wants me to take for Osteoporosis now!!!
Thank you for leaving your review and sharing your experience. It's wonderful that you saw improvement on your DEXA and that your doctor wants you to continue taking Osteo-K Minis.
I haven't had a bone density test yet, (not due for awhile) but I'm hopeful that the results will be better than my last one after using the Osteo K Minis
Thank you for leaving your review. I hope you get the same great benefits so many others have. Please let us know how it goes when you get your next bone density scan.
It's working - gone from osteoporosis to osteopenia.
Thank you for leaving a review. That’s wonderful that your bone scan improved while taking Osteo-K Minis.
My bone scans have improved!

The Osteo-K minis helped me move from osteoporosis to osteopenia along with a good workout 3 times a week!! My doctor was impressed. The osteoporosis occurred after a head on collision with a ***** driver in my 50’s.
So glad Osteo-K helped you! Thank you for the review and for sharing your experience.
Have been using this wonderful product since in it came on the market many years ago. I am in my mid 80's and have great bone structure and a few times that I have fallen, I have had no injuries!! Keep it coming!!
Thank you for your review. We're glad you're loving the product and it's helping you.
Fast delivery. Hard to assess the effect of this product on bone density. Hoping it will keep this 71 year old body going.
Thank you for the review. I'm glad you had a great experience ordering and that you've invited NBI into your home to help you improve your health.
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.
