Vitamin B12 (B12) deficiency is associated with growth retardation, reduced serum osteocalcin levels, lower bone mineral density, and increased bone fracture risk, yet the underlying mechanisms remain unclear. However, a recent study showed that B12 positively regulates postweaning growth and bone formation via taurine. B12 deficiency causes growth hormone resistance (GH) and IGF1 (Insulin-like growth factor-1) deficiency. In the present study, we aimed to evaluate the effect of B12 deficiency on the axis of GH-IGF1 and serum taurine level.
