Adequate calcium and vitamin D throughout life, as part of a well-balanced diet, may reduce the risk of osteoporosis. Osteo-K provides additional nutritional support by combining calcium and vitamin D3 with MK4 derived from Orange Jasmine (Murraya paniculata) leaf geraniol extract.
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.
In addition to providing calcium (1000 mg/day) and vitamin D3 (2000 IU/day) for bone health, Osteo-K delivers 45 mg of MK4® (menaquinone-4) per day to more closely match the clinical trials.
MK4 has many positive effects on the body. Research on MK4 (45 mg/day taken in divided doses) shows that it builds stronger bones by promoting healthy bone density and bone matrix, which are associated with reducing fracture risk.
Clinical Trials: More than 25 clinical trials involving over 7000 people show that MK4 (45 mg/day in divided doses) maintains strong bones. One meta-analysis of clinical trials concluded that MK4 (45 mg daily) maintains strong bones as indicated by 70% fewer fractures in clinical trial volunteers (Cockayne S et al. 2006;166(12):1256-1261).
Another review of the data that evaluated 19 randomized, controlled clinical trials involving 6,759 volunteers reached the same conclusion--MK4 (45 mg/day in divided doses) maintains strong bones as indicated by reducing fractures in clinical trials (Huang ZB et al. 2015;26(3):1175-1186).
A more recent systematic review and meta-analysis published in 2022 confirmed the earlier research. This study pooled data from 10 randomized, controlled clinical trials with 5,413 women ages 45-81 years old. The data showed that MK4 promotes maintains strong bones as indicated by 62% fewer fractures in volunteers (Ma ML et al. 2022;10:979649).
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.
CAUTION: People taking the anticoagulant medication warfarin (Coumadin) should not take this product since vitamin K interferes with this medication.
Directions: Take three capsules twice daily with food.
180 capsules per bottle, a 30-day supply

Long Term Great Results
I have been using Osteo-K for over 15 years and my physician is now a believer. I have been doing weight bearing exercises, watching my food intake, and taking Osteo-K. End result, bone density is stable.
Thank you for sharing how much Osteo-K has helped you.
Has Saved Me Once Again
I have been taking Osteo-K for several years and in that time did not have any fracture. Most recently I fell at 3 am. I sustained a very painful contusion on my left buttock so bad that I couldn't sit down on that side for several weeks. I sustained a long wound on my upper arm and have been treating that with lymph massage. After 4 weeks of that I am finally clear. The x-rays were negative for hip and femur!! Thank you so much. It hurt but nothing was fractured!!
It's wonderful how much Osteo-K has helped you! Thank you for sharing your experience and leaving a review.
Great product. Have been using Osteo K for years now! Won’t buy anything else. Thank you NBI!
Thank you for leaving a review. I'm glad to read that Osteo-K is helping you.
This is the best calcium supplement I have ever taken. I can actually feel the strength in my bones. There are so many calcium supplements available these days, many of which I have taken. and I have never felt as strong as I do now since taking Osteo-K. I've already ordered three more bottles and will continue to take them as long as they are offered. Excellent product!!! Highly recommended!!!
Thank you for writing a review.
I use this and it is working. I have an improved bone density scan!!

I've only been taking it for a week but I did observe that my chronic hip pain went from a 4-5 and a limp to .5 - 1.5 without a limp
Osteo-K!! Needing good calcium absorption and that’s what Osteo-K does!!
Thank you for leaving a review. I'm glad Osteo-K is helping you.
This supplement supplies the exact nutrients prescribed by my doctor for maintaining bone health….calcium and vitamin d in the exact ratios. I love that it is capsules, easy to take, no adverse side effects (constipation, etc.). It is definitely worth the money to prevent broken bones and to continue my active 70's lifestyle. I am positive that my next bone scan in 2 years will show improvement from taking this high quality product.
I'm glad Osteo-K is working for you. Thank you for writing a review.
