NBI's Osteo-K is a bone health supplement that combines calcium, vitamin D3, and a specific form of vitamin K2. The formula is designed to support bone density and matrix, with the manufacturer citing clinical research on its key ingredient. It provides calcium as calcium citrate and vitamin K2 as MK4 (menaquinone-4), which is derived from orange jasmine leaf geraniol extract.

The manufacturer highlights that the 45 mg daily dose of MK4 matches the amount used in over 25 clinical trials involving more than 7,000 people, referencing specific meta-analyses that studied this dosage for bone health outcomes. They note that research suggests combining MK4 with vitamin D3 may provide greater support for bone mineral density than either nutrient alone. The product is part of a line that includes different versions for varying calcium needs.

This version comes in a bottle of 180 vegetable capsules, providing a 30-day supply at the recommended serving of three capsules twice daily with meals. It is formulated without dairy, gluten, or soy.
