The Los Angeles cardiologist urges consumers to rethink nightly sleep gummies and treat melatonin like a medication, not a vitamin.
A New Warning for America’s Favorite “Harmless” Sleep Aid
Melatonin has long been seen as a gentle, natural way to drift off faster, but a new study now suggests that long-term daily use may be associated with an increased risk of heart failure. This finding has raised concerns from leading Los Angeles cardiologist Dr. Ernst von Schwarz, who is urging the public to reconsider using melatonin as a nightly sleep crutch.
The triple board-certified cardiologist, scientist, and UCLA professor stresses that melatonin is generally safe when used occasionally. But daily, prolonged supplementation is a different story. “Melatonin should not be taken every single night,” he explains. “It is a hormone. And like any hormone, long-term use can disrupt natural cycles and potentially cause harmful effects.”
Daily Melatonin vs. Daily Aspirin
Dr. von Schwarz compares today’s melatonin trend to the once-popular habit of taking daily aspirin. For years, aspirin was treated as harmless—until evidence showed that chronic use could damage the stomach, intestines, and kidneys. “The same false sense of safety exists with melatonin,” he says. “Just because it’s sold over the counter does not mean it is risk-free.”
He encourages people to treat melatonin with the same caution as any medication, not as a nightly vitamin.
A Trusted, Nationally Featured Expert
Dr. Ernst von Schwarz is a triple board-certified clinical cardiologist and a global leader in stem cell research with 150+ published papers. Dr. von Schwarz is an expert and speaker at international conferences. Dr. von Schwarz is frequently featured in national media for his medical expertise, including appearances in Men’s Health, FOX11 News Los Angeles, the New York Post, and many other outlets. Known for translating complex science into clear, practical guidance, he is often sought after for commentary on heart health, longevity, and anti-aging trends.
A New Era of Longevity in Beverly Hills
The cardiologist recently opened a state-of-the-art regenerative and stem cell clinic in Beverly Hills, designed to help individuals live beyond 120 with their vitality, mobility, and appearance intact. His work focuses on evidence-based regenerative medicine, an area of health now gaining massive traction in beauty and wellness culture.
As longevity treatments become a booming trend, Dr. von Schwarz is bringing scientific credibility and ethical clarity to a field often clouded by marketing myths. He is outspoken about separating fact from hype, especially when it comes to stem cell therapies, peptides, IV infusions, and emerging anti-aging technologies.
Cutting Through the Noise
While social media is filled with quick fixes and “miracle” wellness routines, Dr. von Schwarz emphasizes that true regenerative medicine must be grounded in real science, not viral trends. His message is simple: living longer should also mean living better, stronger, sharper, and biologically younger, but safely.
The Takeaway
Melatonin remains a useful sleep aid when used occasionally. But according to Dr. von Schwarz, the nightly habit many Americans have formed may come with risks we are only beginning to understand.
“Natural doesn’t mean harmless,” he says. “If you rely on melatonin nightly, talk to your doctor. Identify what is causing the sleep disturbance. There are safer, healthier long-term approaches.”
With decades of clinical expertise and a leadership role in longevity research, Dr. von Schwarz continues to be one of the most trusted voices guiding the public toward informed decisions in a rapidly evolving wellness landscape.
