The Link Between Excessive Niacin Intake and Heart Disease

A recent study has linked a niacin derivative to an increased risk for cardiovascular events, prompting questions about the safety of niacin intake. The findings suggest that excessive niacin intake may be harmful, leading to potential adverse effects on cardiovascular risk. While some experts advise avoiding niacin supplements and high-protein diets, others caution that a causal link has not been proven and further research is needed. The study's implications also raise questions about niacin fortification in food and its use in skin cancer prevention, with differing opinions on the effects of nicotinamide supplementation.
