The Problem

The supplement industry relies on you taking them at their word.

Without hours of reading clinical trials and demanding lab results, you are flying blind. We do the heavy lifting to expose which brands actually deliver on their promises.

Opaque ingredient labels

"Proprietary blends" hide underdosed ingredients. You rarely know if you're getting the active, bioavailable form or just cheap filler.

Meaningless marketing claims

Brands make bold health claims that lack clinical backing. The supplement industry is built on hype, not verified scientific evidence.

Untrustworthy tracking

Heavy metals, contaminants, and lack of GMP certification are rampant. If it's not third-party tested, you are gambling with your health.

Our principle

We're not doctors. We're librarians.

Nutripedia presents published research. We don't interpret your symptoms, diagnose conditions, or recommend treatments. Every claim on this site is cited back to the peer-reviewed source it came from.

That distinction matters. By staying squarely in the role of a research library, we sit firmly outside MHRA medical device classification, and firmly inside what a well-informed consumer actually needs: the underlying evidence, not another opinion.

We're UK-based, independent, and operated by ALDR Ltd. No sponsored placements. No affiliate bias baked into scores. Just research, verification, and transparent criteria.
