`supplement_recent_changes`

Pack: nih-supplements · Endpoint: https://gateway.pipeworx.io/nih-supplements/mcp

New supplement product labels entered into NIH’s Dietary Supplement Label Database (DSLD) since a given date — the one NIH supplement upstream that publishes a queryable change signal. Returns each new label’s id, brand, product name, and entry date, newest first; deterministic on replay. Scope is stated, not guessed: DSLD does not publish off-market (withdrawal) transitions as dated events, and neither ODS fact sheets nor NCCIH herb pages publish a queryable list of content-update dates — the response says so explicitly instead of pretending to cover them. Each supplement_factsheet response carries its own ‘reviewed’ date for direct sweeping.

Parameters

Name	Type	Required	Description
`since`	string	yes	Cutoff date, YYYY-MM-DD. Labels entered into DSLD on or after this date are returned.
`limit`	number	no	Max new labels to return (default 50, max 200). If more entered since the cutoff, the response sets truncated: true.
