Implications of Daily Multivitamin Use

This chapter explores the impact of daily multivitamin use on mortality, discussing a study that revealed a 5% increase in mortality risk for daily users compared to non-users. It delves into the potential harms of certain vitamins when taken in supplemental form, and emphasizes the nuanced approach needed for recommending multivitamins, especially for specific groups with medical conditions. The chapter also touches on the lack of real benefits on exercise-related performance from multivitamin supplementation unless in specific contexts like relative energy deficiency in sport (RED-S).
