## FAQ

### Is melatonin a peptide?

No. It is an indoleamine hormone synthesised from tryptophan via serotonin. It is included in this reference library as a related research compound.

### Is melatonin FDA-approved?

Not as a drug in the United States, where it is sold as a dietary supplement. Several other countries, including much of the EU and the UK, regulate it as prescription-only.

### Why does melatonin content vary between products?

Because it is regulated as a dietary supplement in the US rather than as a drug, independent analyses have repeatedly found actual content differing substantially from what the label states.
