Paste the text of a Supplement Facts panel, or load an example, and see what each part of the label tells you and what it leaves out.

Assumptions
Label rules come from the federal regulation on supplement nutrition labeling, which sets the Supplement Facts format, the 'Daily Value not established' marking, source forms, plant parts, extract labeling and proprietary blends 1.
Structure/function claims must carry the FDA disclaimer, and labels may not claim to diagnose, treat, cure, mitigate or prevent disease 2.
Piperine raises blood levels of some compounds by blocking how the body clears them 3.
Limitations
This is pattern matching on text, not a review. It can miss terms, misread unusual formatting, or flag a word used innocently.
It explains label language. It does not judge whether a product is safe, effective, accurately labeled or right for you.
A label can be wrong. Independent tests have found products containing far more or less than stated 4,5.
