"Link Between High Niacin Levels and Heart Disease Risk: Study Findings"

A recent study published in Nature Medicine suggests that high levels of niacin, also known as vitamin B3, may increase the risk of heart disease by triggering inflammation and damaging blood vessels. While niacin is essential for energy metabolism and skin health, the study raises concerns about its impact on heart health, particularly in high doses. Experts caution against routine intake of niacin supplements and recommend consulting with a healthcare provider, especially for those currently taking large doses of niacin for cholesterol management. The study prompts a reevaluation of the fortification of flour and cereal with niacin in the U.S., and emphasizes the importance of obtaining vitamins from food sources and maintaining a balanced diet.
