1mg vs 10mg melatonin — the dose math
Two numbers tell the whole story. The aisle ships 5–10 mg per gummy. Your body produces 0.1–0.3 mg per night on its own. 1 mg is the dose used in sleep-onset studies — a tenth of the usual melatonin dose. So why is the standard dose ten times higher than the research?
The supplement aisle is built around tolerance, not biology. 10 mg gummies started as a marketing decision — a stronger dose felt more potent at the shelf. The literature didn’t catch up; the bottles never came down. Most people are taking a dose that overshoots their system by 30–100×.
Higher doses don’t mean better sleep. Past the 1 mg threshold, more melatonin doesn’t make you fall asleep faster. Research suggests the curve flattens fast. What it does is leave more hormone in your system the next day, which is what can leave the morning heavy-headed.
1 mg + the right botanicals does more than 10 mg alone. Phew’s formula pairs the 1 mg dose used in sleep-onset studies with valerian root, lavender, chamomile and hibiscus — a wind-down stack that does the supporting work melatonin alone doesn’t.
