Cardiologist Reveals 5 Supplements to Avoid: Serious Health Risks

Supplements to Avoid: A Cardiologist's Warning June 1, 2025 -- In a recent video, Dr. Evan S. Levine, MD FACC, a cardiologist based in the US, issued a strong warning about five common supplements that he believes should be avoided. His concerns center on the potential for serious health consequences, including liver damage, heart attacks, and strokes. "My top five supplements to avoid are those with high levels of niacin, green tea extract, and anything with erythritol, xylitol, or pthalates," Dr. Levine stated in his video. "These are commonly found in many supplements, and many people are not aware of the potential risks." Dr. Levine's concerns about niacin and green tea extract are rooted in their potential to cause liver damage. He also highlighted the dangers of artificial sweeteners like xylitol and erythritol, which have been linked to increased risks of heart attack and stroke in recent studies. He further warned against pthalates, which are also associated with cardiovascular problems. The cardiologist's warning extends to ephedra, a weight-loss supplement banned in the United States due to its association with increased risks of heart attack, stroke, and seizures. Dr. Levine's advice underscores the importance of consulting a physician before taking any supplements and carefully researching the ingredients of any supplement before consumption. His video has already garnered significant attention online, with over 2000 views in less than three hours.
