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.

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.

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.

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 decreasing fractures more than 70% (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 (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).

Each bottle contains a 30-day supply.


Collagen is the most abundant protein in the body. It forms the scaffolding that provides strength and flexibility to your skin, nails, bones, joints and organs. Babies’ skin is plump and soft and bounces right back because they have lots of healthy collagen.

But as you age you and have less collagen, lines, wrinkles, drier and sagging skin start staring back at you in the mirror. What you see on the outside is happening on the inside too. Joints may start to creak, crackle, twinge and ache. As skin collagen declines, so does bone collagen and bone mineral density. Women with thin skin have a higher incidence of osteoporosis.

NBI’s Collagen delivers 10 grams of non-GMO, unflavored, hydrolyzed Types I and III collagen to promote healthy skin, bones, joints and nails. It's paleo- and keto-friendly and derived from grass-fed, pasture-raised cows.

Our collagen powder matches or exceeds the amount of collagen used in clinical trials for bone, joint and skin health. And it doesn’t contain any of the bad stuff—absolutely no antibiotics, gluten, hormones, pesticides or solvents. It’s also soy-, dairy- and sugar-free.

Each bottle contains a 30-day supply.
