About

Osteocalcin is a type of vitamin K2-dependent protein, and many studies have confirmed that vitamin K2 has anti-osteoporosis effects, and has preventive and therapeutic effects on a variety of diseases such as nervous system, cardiovascular disease, immune disease, and glucose metabolism. However, as a pleiotropic vitamin and nutrient, vitamin K2 does not have an exact normal range like other vitamins, when it needs to be supplemented, and in what regimen. Different organizations have different opinions on the recommended intake of vitamin K. Thus, this study intends to preliminarily obtain the reference interval of serum vitamin K2 by conducting clinical research in healthy people in the Beijing-Tianjin-Hebei region, and analyzes different factors, such as gender, age, and place of residence, to compare their level differences and changing trends, and to provide data reference for the recommended intake of vitamin K2 for people with vitamin K2 deficiency.
