Introduction: Osteocalcin has been shown to have an inverse relationship with blood glucose, insulin resistance and adiposity.
Objective: To determine osteocalcin normal serum concentration in Mexican healthy adults and compare it with values reported in other populations.
Method: Carboxylated and undercarboxylated osteocalcin serum concentrations were determined in 100 healthy adults by means of enzyme immunoassay; osteocalcin total concentration was calculated.
