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

I’ve been taking Osteo-K for about two years now and the difference in my level of bone pain is astounding! I have a history of osteoporosis and I’ll never be without this supplement.
Thank you for leaving a review and sharing how much Osteo-K is helping you.
Improvement with Osteo K and Exercise!
I have been taking Osteo K since about 2017. Shortly before that I broke my hip when I fell off a bicycle at age 49 and my DEXA showed that I had Osteopenia. My Naturopath recommended Osteo K. Two years later, my Osteopenia had progressed to Osteoporosis even though my husband and I went on 4-5 mile hikes about once a week. I was disappointed, but increased my exercise to include more frequent walks, balance exercises, and weights. My third DEXA was in October 2022. It showed that I had gone back into Osteopenia!!! Thanks for your help with my bone health!
Thank you for sharing that Osteo-K helped improve your bone health.

Ten year customer
I have been taking Osteo-k since 2011. Since that time I have improved with each Dexa scan.
Thank you for sharing your review and being a customer for more than a decade.
Very positive. After just a few weeks my elbows stopped hurting.
Thank you leaving a review. Glad your elbow is feeling better!
Sustained BMD increase
I (can’t and) don’t take prescription drugs, only these supplements, and try to maintain a healthy lifestyle. My BMD increase was the same as last year, despite being older. I now only have osteoporosis left in selected areas in my femur.
Thank you for your review and sharing how Osteo-K has helped you.
I have been taking Osteo-K for about two years now and have noticed a huge improvement in the bone pain I was experiencing. Now I am able to enjoy playing pickleball again!
