Is This Supplement Legit

Decision engine

Compare supplements and products

Open published ingredient pairs or build a product-vs-product compare from SKUs on file.

Product compares use the same rubric as single-SKU pages: additives, label clarity, transparency, value, safety.

Search also routes ingredients, SKUs, brands, compares, and best lists - try two names with “vs”.

Compare two real products

Pick two SKUs; we normalize to one shareable compare URL.

Different products only. Slugs are normalized to one canonical order (a-vs-b).

Suggested product matchups

Ingredient comparisons
