A new study linking melatonin use to a 50% higher risk of heart failure has sparked widespread concern — but experts say the findings have been overstated.

Researchers analyzed data from over 110,000 adults with insomnia and found that those who took melatonin for at least one year had higher rates of heart failure (4.6% vs 2.7%). However, doctors caution that the results show correlation, not causation. Many participants already had underlying health conditions or chronic insomnia that may have contributed to the increased risk.

Health specialists emphasize that melatonin remains safe for most people when used occasionally and at standard doses. The main takeaway, they say, is not to panic — but to use the supplement responsibly and under medical supervision, especially for those with existing cardiovascular issues.
