Age- and sex-specific reference intervals and determinants of plasma vitamin B6 metabolites in healthy Chinese adults

We established population-specific, age- and sex-stratified RIs for vitamin B6 biomarkers in healthy Chinese adults, providing a baseline for clinical and laboratory assessment of vitamin B6 metabolism. We also found that ALP, albumin, renal function, and serum phosphorus were closely related to the vitamin B6 status in both males and females.
