High levels of niacin linked to heart disease, new research suggests

• Elevated niacin levels may increase the risk of heart disease, counteracting its intended benefits on cholesterol.
• Niacin supplements, often used to boost "good" cholesterol, may not provide the expected cardiovascular advantages.
• Excessive niacin intake could potentially harm heart health, contradicting previous assumptions about its benefits.
• The findings underscore the importance of caution when using niacin supplements and suggest reevaluation of their role in cardiovascular health.
• Experts recommend obtaining nutrients like niacin through a balanced diet rather than relying solely on supplements to mitigate potential risks.
