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 (400 mg/day) and vitamin D3 (2000 IU/day) for bone health, Osteo-K Minis delivers 45 mg of MK4® (menaquinone-4) per day to more closely match the clinical trials.
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.
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 two capsules twice daily with food.
120 capsules per bottle, a 30-day supply

My DEXA improved
My last DEXA scan (after using this product for just over a year) showed my bones went from Osteoporosis to Osteopenia; pretty impressive for someone in their 60's!
That's wonderful! Thank you for leaving a review.
Love these for my bones!
I love the size of these and the fact that they also have vitamin K, which I was not taking. Doctor’s only tell you to take calcium. I was so glad to find this company after listening to a podcast. I feel confident I’m taking the right vitamin for my bones.!!
High quality recommended by my Naturopathic Dr.
It’s excellent quality and have been using for 8 years now. It is absorbed as other brands were not. Keep offering discounts please.
I have been taking Osteo-K Minis since March 16th but only one with breakfast and one with dinner. On March 27th I added a third one daily and plan to eventually take 4 per day per the product recommendation. I am sleeping better and hope my bones will benefit.
I’m currently taking my 7th month of the Osteo-K minis and plan to continue. I have a doctor’s appointment in July and will ask for a bone density test. Hopefully, my osteoporosis will be shown to be in reverse.
Bone density increased 23.7%!
I've been taking Osteo K minis since April 2020 - the bone density decreased in March 2021. I started rowing 30min/5000m per day November 2021 - my bone density increased by 23.7% in lumbar spine; remained the same in the hips. I'm very pleased, even if I'm not sure what part rowing played vs the Osteo-K Minis.
Thank you for sharing how much Osteo-K Minis has helped you.
So far, so good! I have been looking for a product that contains MK-4 instead of MK-7 and this was the best one that I could find. I started taking it the day it arrived in the mail. I am only taking 1 in the morning and 1 with dinner, at least for now. I have had problems feeling sluggish with other calcium products and have not experienced that with Osteo-K Minis.
Thank you for your review and for sharing your experience. I’m happy to read that Osteo-K Minis is working for you.
Excellent experience with Osteo K Minins.
