The real benefits of vitamins and dietary supplementation on health outcomes have always been mired in controversy,and to date,contradictory studies continue to be published to highlight their benefits when downplaying possible adverse effects.!This recently published National Health and Nutrition Examination Survey(NHANES)database study population investigating the role of niacin on erectile function reported that higher niacin intake,specifically in the highest tertile,was associated with a decreased risk of erectile dysfunction(ED)compared to the lowest tertile,showing an odds ratio(OR)of 0.56(95%confidence interval[CI]:0.37-0.85)based on 863 participants with ED from a pool of 3184 adults.2 Further analysis of dose-response curves and interaction analyses found a negative correlation between dietary niacin intake and the risk of ED,suggesting that a higher dietary niacin intake is associated with areducedriskof ED.
