Abstract

The aim of the study was to assess whether circulating vitamin concentrations are circadian periodic, and if so, to estimate the phase relations among vitamins A, E, C, and beta-carotene. Plasma concentrations of vitamins A, E, and C, and of beta-carotene are circadian periodic, with peak values found in the early morning hours.
