Association of erectile dysfunction and daily food thiamin intake among men in the USA.

ABSTRACT:

Background

Erectile dysfunction (ED) is a common male health issue influenced by vascular and neurological factors. Although prior studies have linked micronutrients to ED, the role of thiamin (vitamin B₁) remains underexplored. Given its key role in energy metabolism and nervous system function, this study aimed to investigate the association between dietary thiamin intake and ED among men in the USA.

Methods

In this study, data from two cycles (2001-2002, 2003-2004) of the National Health and Nutrition Examination Survey were used, which included information on daily riboflavin intake from food and self-reported ED.
