Association between vitamin intake and biological aging: evidence from NHANES 2007-2018.

ABSTRACT:

Background

The combined effect of vitamin mixture on biological aging, along with the specific contribution of individual components, remains unclear. This study investigated the associations between a mixture of 11 dietary vitamins and biological aging.

Methods

This cross-sectional study included 15050 adults from NHANES 2007-2018. Daily intakes of 11 vitamins were estimated using the multiple source method to account for within-person variation from two 24 -h recalls, incorporating both food and supplement contributions. Total vitamin intake was calculated as their sum. Biological aging was assessed using three established indicators: KDM-acceleration and PhenoAge-acceleration (derived as regression residuals of biological age on chronological age), and homeostatic dysregu
