How Much Melatonin Is in Supplements? 2,674 NIH Labels, Counted

The US National Institutes of Health keeps a public database of supplement labels. We pulled every melatonin product in it, read the amount per serving off each label, and counted. This page is the count, the method and the download.

The short answer

• 2,674 labels list melatonin with an amount per serving, from 620 brands, entered into the database between 2011 and 2025.
• The median label is 3 mg per serving. The single most common amount is 3 mg, on 33% of labels.
• 34% of labels sell 5 mg or more, and 13% sell 10 mg or more. Only 19% are 1 mg or under, the range closest to what the body makes on its own at night.
• Among products the database lists as currently on the market, the picture is slightly higher: median 3 mg, 38% at 5 mg or more, 15% at 10 mg or more.
• 273 labels are aimed at children. Their median is 3 mg, and 30% of them are 5 mg or more.
• The highest amount on a label is 80 mg in one serving.

How much melatonin is in supplements, label by label

Most common amounts: 3 mg (890 labels), 5 mg (485 labels), 1 mg (359 labels), 10 mg (290 labels), 2 mg (143 labels). The chart counts every label with a melatonin amount; green bars are 5 mg and under, rust bars are 5 mg and over.

Is 10 mg of melatonin too much?

By the research, yes for most adults, and the labels show how normal it has become. One label in 8 in this database is 10 mg or more. In clinical trials, amounts of 0.3 to 1 mg raised blood melatonin to the level the body produces on its own at night (in the placebo-controlled MIT crossover trial of older adults, 0.3 mg was the amount that worked best), 1 to 3 mg were the usual trial amounts, and higher amounts were not more effective in head-to-head comparisons but did last longer into the morning. A 10 mg tablet is roughly thirty times the 0.3 mg that restored night-time blood levels in the MIT trials of older adults. Nothing on this page is a dosing instruction: the right amount for a given person is a conversation with their clinician, and this page relates to melatonin as an ingredient and is not the Veluna product.

By format

Tablets dominate the database. Gummies, the fastest-growing format in stores, are also the format a 2023 laboratory analysis found least likely to match its label; see what testing found about melatonin label accuracy.

The highest amounts on a label

Children's products

273 labels in the set are marketed for children or list a children's target group. Their median amount is 3 mg, the same as the adult median, and 30% are 5 mg or more. US poison-control centres reported a 530% rise in calls about children ingesting melatonin between 2012 and 2021, most of them unintentional. Paediatric use is a clinician's decision.

Method

1. Source. The NIH Office of Dietary Supplements' Dietary Supplement Label Database (DSLD), queried through its public API (version 9) on 1 October 2026 for every label matching "melatonin".
2. Inclusion. A label counts if melatonin appears in its ingredient rows with a numeric amount for the first listed serving size. Labels that list melatonin only inside a proprietary blend without an amount, or in a unit we could not convert, are excluded (210 labels).
3. Units. Micrograms were converted to milligrams. Where a serving size is a range, the amount for the first serving size is used.
4. On market. The database's own off-market flag. Labels change and products are discontinued, so "on market" means "the database had not marked it discontinued" on the pull date.
5. Children's products. Labels whose target group names children, infants, toddlers, kids or teens.
6. Highest-amounts table. It omits 44 labels whose product name states a different amount from the per-serving figure (usually a two-tablet serving, sometimes a database entry that needs checking). Those rows stay in the CSV.
7. What this is not. A count of labels, not a laboratory measurement. Independent testing has found that measured melatonin content often differs from the label, in both directions. It is also not a census of the US market: the DSLD is large but not complete.

Where Veluna sits

For reference only: Veluna's two melatonin products are 1 mg per strip (Sleep Strips) and 2 mg per two-capsule serving (Sleep Formula). On this database, 1 mg is lower than 81% of labels, and 2 mg is lower than the median. The low-dose melatonin collection shows both labels in full.

These studies measured melatonin products and melatonin as an ingredient in volunteers. None of them tested a Veluna product; this page relates to individual ingredients and is not the Veluna product.
