Micronutrients & recovery
Vitamin K supplementation effectively increases gamma-carboxylated osteocalcin levels but does not significantly prevent bone loss or reduce fracture risk in elderly populations.
Taking Vitamin K supplements will improve your osteocalcin levels, but current evidence suggests this does not prevent fractures or bone loss in older adults. Do not rely on Vitamin K alone for osteoporosis prevention; focus on weight-bearing exercise and adequate calcium/vitamin D intake.
GoodRefutesHIGH confidence
Recent randomized controlled studies suggested that vitamin K treatment was not effective for preventing vertebral fractures and bone loss... no other differences concerning bone loss or risk fracture between the two groups were found
Why this rating
Based on randomized controlled trials (RCTs) showing no clinical benefit despite biochemical markers changing.

- Uncarboxylated osteocalcin (un-OC) acts as an endocrine hormone that regulates energy metabolism by stimulating pancreatic beta-cell proliferation, insulin secretion, and adiponectin production, thereby improving glucose tolerance and reducing fat mass.Moderate
- Osteocalcin regulates bone mineralization by inhibiting hydroxyapatite crystal growth and nucleation, although its absence leads to smaller, less perfect crystals rather than a total failure of mineralization.Moderate
