Collagen Peptides
What the European Food Safety Authority and the United States National Institutes of Health have published about collagen peptides intake, and what the catalogue records. Reference figures and citations only.
Stacky is an organisational tool, not a medical device. It does not provide medical advice, and nothing on this page says what collagen peptides does. Talk to a doctor or pharmacist before starting, stopping or changing what you take.
Published intake references
Each figure is one authority’s published value, with the kind of figure and the people it applies to as that authority stated them. Where the EU and the US differ, both are shown and neither is averaged or converted. Only a tolerable upper intake level sets a ceiling. A recommended or adequate intake is context, not a limit.
European Union — EFSA
United States — NIH ODS / IOM
“None established” means that authority examined collagen peptides and set no figure. A substance for which Stacky holds no published reference has no row here, and no page.

Forms recorded: Powder.
Indexed studies
A study reaches this page only if its own title names Collagen Peptides or one of its recorded alternative names, and does not name a disease or clinical condition. The second rule removes papers that are about collagen peptides; a title naming a condition beside a substance reads as a claim, and this page makes none. Titles are the studies’ own words, newest first. A study being listed is not a statement that collagen peptides does what it set out to test. How this list is built →

About this page
Stacky is a supplement tracking app. It renders what you take and what published sources say about it; it does not tell you what to take. Every figure on this page names the authority that published it and links to that authority’s own page.
Not on this page: a dose of our own, a grade, a verdict on whether collagen peptides works, or any statement that it treats, prevents or improves a condition. How these pages are built →
Figures are read from the authorities’ published tables and can go out of date when those tables are revised. If one here is wrong, tell us at support@stacky-app.com and we will check it against the source.
