This hormone supplement has become the go-to for better sleep, often viewed as a safe and natural alternative to prescription sleep aids. But a new, groundbreaking study is prompting doctors and researchers to urge a bit more caution.
Presented at the American Heart Association’s Scientific Sessions 2025, the research suggests that long-term use of melatonin supplements may be linked to some unexpected negative health effects.
Is Your Nightly Melatonin Habit .Beyond the Sleepy Feeling: What Exactly is Melatonin?
Before we dive into the new findings, let’s get on the same page about what melatonin is. It’s a hormone naturally produced by your brain’s pineal gland. When it gets dark outside, your body releases it to signal that it’s time to wind down and prepare for sleep.
Melatonin supplements are synthetic versions of this hormone. They can be incredibly helpful for specific situations, like:
- Managing jet lag
- Adjusting to a new shift-work schedule
- Occasional, short-term sleeplessness
- The problem may arise when occasional use turns into a long-term, nightly habit.
The New Findings:Is Your Nightly Melatonin Habit. What the 2025 Research Revealed
The abstract, labeled MP2306, analyzed data from a large group of adults over several years. The researchers were particularly interested in the cardiovascular health of those who reported regular melatonin supplement use.
Here’s the key takeaway: The study found a significant association between long-term melatonin use and an increased risk of developing hypertension (high blood pressure) and other metabolic issues.
It’s crucial to note the word association. This means the research found a link, not necessarily a direct cause-and-effect. However, the connection was strong enough to warrant further investigation and a more cautious approach from the public.
Researchers theorize that because melatonin influences more than just our sleep-wake cycle—it also plays a role in regulating blood pressure, blood sugar, and body temperature—prolonged, high-dose supplementation could potentially disrupt these delicate systems.
So, Should You Stop Taking Melatonin?
Don’t toss your bottle in the trash just yet! This new information isn’t meant to panic you, but to empower you to make smarter choices for your health.
