New York, N.Y. — A leading cardiologist has raised concerns over widely-used dietary supplements that may jeopardize heart and liver health. Dr. Evan Levine, a cardiologist at Mount Sinai, emphasized that while many people rely on these products to boost their well-being, misusing certain supplements could result in severe health issues, including heart attacks and liver failure.
Each year, more than 800,000 Americans suffer from heart attacks or strokes, according to the Centers for Disease Control and Prevention (CDC). The statistics reveal a troubling trend: around 138,000 individuals succumbed to strokes in 2020, and a death from heart disease occurs every 33 seconds in the United States. Alarmingly, even younger adults are increasingly reporting cardiovascular events, underscoring the need for further scrutiny regarding the health implications of supplements.
Dr. Levine identified five specific supplements that could pose significant dangers if not taken with caution. Niacin, also known as Vitamin B3, is typically consumed through food or occasionally prescribed to manage cholesterol levels. Nevertheless, excessive doses can lead to inflammation of blood cells and an increased risk of cardiovascular disease. A recent study published in Nature Medicine found that high niacin intake may double the likelihood of developing heart-related conditions by promoting the formation of arterial plaque, which disrupts healthy blood flow.
Another supplement of concern is green tea extract. Although it’s praised for its antioxidant properties, Dr. Levine warned that high doses of this extract can severely impact liver function. While green tea itself poses minimal risks, concentrated forms can lead to hepatotoxicity. Individuals with pre-existing health conditions such as diabetes or liver issues should exercise particular caution.
Sweeteners like erythritol and xylitol, commonly found in sugar-free products, also raise alarm bells. Despite their FDA approval and benefits in managing blood sugar levels, these substitutes may increase the risk of heart attacks and blood clots. Dr. Levine highlighted studies indicating a correlation between erythritol consumption and an elevated likelihood of cardiovascular events.
Further, softgel capsules, which often contain phthalates—compounds used to enhance plastic flexibility—may be harmful when ingested. Research has suggested that these chemicals can cause inflammation in artery walls, leading to narrowed arteries and increased risk for blockages or aneurysms. The potential for oxidative stress from phthalates adds another layer of concern, as it may further compromise heart health.
Health experts advise individuals to be well-informed about their supplement choices and to consult healthcare providers for personalized advice. Although supplements can serve a purpose, the balance between their benefits and risks must be carefully managed.
As people increasingly seek alternatives to improve their health, vigilance regarding the consumption of certain supplements is essential. Proven strategies to promote heart and liver health include a balanced diet, regular exercise, and routine health check-ups, which should not be overshadowed by reliance on unmonitored dietary additions.
