Adequate calcium and vitamin D throughout life, as part of a well-balanced diet, may reduce the risk of osteoporosis.
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 (800 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.
NBI's MK4 is a 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) shows that it builds stronger bones by promoting healthy bone density and bone matrix, which are associated with reducing fracture risk.
Bone Support and Fracture Reduction: Two meta-analyses of clinical trials on MK4 in people taking MK4 (45 mg/day) concluded that this nutrients 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. 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 (Huang ZB et al. 2015;26(3):1175-1186).
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

Osteo-K Bone Support
This was recommended to me by my Naturopathic doctor. Ordering was easy, and items were shipped in a timely fashion. I need bone support due to some immunotherapy medications I am taking for Stage 4 cancer. Hopefully this is the right choice.

Life Saving Supplement
I have been taking Osteo-K for years. I refused to take osteoporosis drugs and opted to take Osteo-K. One military physician dismissed me from care because of this. The next one who got me as their patient was amazed at how Osteo-K and weight resistance exercise held it at bay and I even gained some bone density. I am so grateful and a customer for life!
Thank you for leaving your review. It’s wonderful to read how your doctor is so happy with how your bones are doing.
