Chronotherapeutic Use of Vitamin C to Reduce Morning Cardiovascular Risk
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will test the efficacy of Vitamin C to counteract morning cardiovascular (CV) risk markers in a randomized, double blind, placebo controlled crossover pilot study. The participants will also perform morning typical behaviors such as arousal from sleep, change in posture (getting out of bed) and mild intensity physical activity; identical to the stressors encountered in everyday life. Primary dependent variables are markers of cardiovascular risk including vascular endothelial function and oxidative stress.
