About

Ingredient Checker answers a narrow question well: what is actually in this, and does it matter? Ingredient labels are written for regulators, not for the person holding the package, and searching an additive usually returns either a marketing page or someone's blog post about toxins.

Where the data comes from

Every report is built from published regulatory and toxicology sources — FDA GRAS and food-additive status, EU authorisation and E-numbers, JECFA acceptable daily intakes, EFSA no-observed-adverse-effect levels — alongside processing detail and the studies behind each claim. Reports carry their citations so you can check the source rather than take our word for it.

There are 514 ingredients covered today, scoped to what appears in packaged protein and snack products, plus 767 products broken down by what they contain.

What it is not

It is not medical advice, and it will not tell you whether something is safe for you. Individual tolerance, allergies, pregnancy and medication interactions are real and none of them are in this data — those are conversations for a clinician.

It also does not sell the products it describes, and takes no money from the brands in the database.

Coverage

Coverage is honest about its edges. The database grew out of analysing packaged nutrition products, so a mainstream additive that does not appear in them may not be here yet. When an ingredient isn't covered, the assistants say so rather than guessing — that is deliberate, and more useful than a confident answer built on nothing.
