If you've ever woken up more tired than when you fell asleep after taking melatonin, you're not imagining it. More and more people are asking whether melatonin is bad for you — and the answer is more nuanced than most supplement brands want to admit. Here's what the research says and what Flightmode does differently as a melatonin-free sleep supplement.

That heavy, foggy feeling the morning after taking melatonin is so common it has its own name — melatonin hangover. Most over-the-counter doses flood your body with 5 to 10mg when your brain naturally produces around 0.1mg.
That excess lingers in your system for hours, leaving you drowsy well into the next day and defeating the purpose entirely.
Is melatonin bad for you long term? Researchers have raised concerns about nightly use suppressing your body's own production, disrupting hormonal balance, and masking underlying sleep issues.
For anyone who relies on melatonin regularly, it can create a cycle where sleep actually gets worse without it. That's worth considering before reaching for the bottle again tonight.
Flightmode's Sleep formula contains zero melatonin. Instead it uses Magnesium Glycinate to calm the nervous system, Chamomile Extract to ease anxiety, and Phosphatidylserine to lower cortisol.
These ingredients support your body's own sleep process rather than overriding it with a synthetic hormone. You wake up clearheaded because nothing artificial is sitting in your bloodstream.
Most people find Flightmode through travel, but the Sleep formula works just as well in your own bed. The same ingredients that help you rest on a red-eye also support deeper nightly sleep at home.
And if you do fly, the AI planner adjusts your dosing to your route so your body stays in rhythm wherever you are.
After 30 days of using Flightmode, travelers reported:
slept better on the plane†
had more energy during their trip†
recovered from jet lag faster†
†These figures reflect a consumer perception survey of Flightmode users who had followed their personalized plan for at least 30 days. Individual results vary. This product is not intended to diagnose, treat, cure, or prevent any disease.
