why we built dōpo
5 reasons to ditch melatonin.
Your body was ready hours ago. You reached for melatonin anyway, and woke up in a fog that followed you past 6am. If the fix keeps costing you the morning, it might be the wrong fix.
P.S. We are not anti sleep help. We are against guessing what is in the bottle, and against paying for tomorrow to get through tonight.
Start with reason one
the morning tax
The morning fog is a side effect, not a fluke.
You know the feeling. You finally went under, and then the alarm pulled you out of something thick. The fog sits behind your eyes until the second coffee. That grogginess is not you doing melatonin wrong. It is on the documented list.
The NIH's complementary health center lists the reported side effects plainly: headache, dizziness, nausea, and sleepiness. It also notes that melatonin can stay active longer in older people and cause daytime drowsiness. A sleep aid that follows you into the next day is not a small footnote when the whole point was to wake up like yourself.

the wrong tool
It signals darkness. A busy mind is a different problem.
Here is the part the gummy aisle skips. Melatonin is a hormone your brain already makes in response to darkness, and its job is timing. As the NIH center puts it, it helps with the timing of your circadian rhythms, your internal clock. It tells your body what time it is.
That is a different problem than the one you actually have. Your body already knows it is night. Your mind is the part still answering email and holding tomorrow's list at midnight. Melatonin was never designed to quiet that mind. Timing is the only job it has. You reached for a clock when you needed an off switch.
And because it is a hormone, the long-term questions are only getting newer. A preliminary study presented at the American Heart Association's 2025 Scientific Sessions associated long-term melatonin use with a higher rate of heart failure over five years, among adults already diagnosed with chronic insomnia. The Association is explicit that the work is observational, not yet peer reviewed, and cannot prove cause and effect. It is a reason to stay curious about what you take every night, not a scare.

the guessing game
When researchers tested them, most labels were wrong.
Even if you wanted melatonin, you would have to trust the number on the label. Researchers checked. In a 2023 JAMA analysis of 25 melatonin gummy products sold in the US, 22 of the 25 were inaccurately labeled. Only three landed within ten percent of what the label claimed.
The actual melatonin ranged from 74 percent to 347 percent of the stated amount. One product had no detectable melatonin at all, but did contain 31 milligrams of CBD. In that test, the number printed on the front was not a number you could count on.

So we stopped arguing with melatonin and built the thing we wanted instead.
