Dietary creatine and kidney function in adult population: NHANES 2017–2018

Abstract

Consuming more creatine may be associated with an increased risk of renal dysfunction, yet this link remains poorly addressed at the population level. Using 2017–2018 NHANES data, the current study found that the odds ratio for having failing kidneys in 2,955 U.S adults consuming ≥2.0 g/day of dietary creatine compared to low-intake counterparts (<1.0 g/day) was 0.74 (95% CI from 0.39 to 1.38), indicating no significant association between dietary creatine intake and kidney dysfunction.
