Stable study IDs prefer PMID, then DOI, then source URL, then a normalized title fallback. Ingredient relationships are represented separately from study identity so the same paper can be interpreted in more than one ingredient or outcome context without duplicating the paper itself.

FAQ

What does “supports,” “mixed,” or “contradicts” mean?

Those labels describe how a structured study relationship is used for a particular ingredient or claim context. They are kept separate so conflicting evidence is visible instead of averaged away.

Does a study appearing here prove an ingredient works?

No. Study design, sample size, population, dose, formulation, outcome, limitations, replication, and disagreement with other studies all affect confidence. The explorer exposes those details rather than treating citation count as proof.

Why are animal, cell, or mechanism studies included?

They can be useful research context and help explain plausibility, but the explorer labels them separately from direct human evidence so they are not mistaken for clinical efficacy evidence.

Learning context

How this concept connects to supplement decisions

Search and filter the trials, reviews, observational studies, preclinical sources, doses, populations, outcomes, limitations, and evidence directions… Learning pages explain the reasoning layer behind the herb and compound library. They are designed to make mechanisms, evidence quality, safety tradeoffs, and product claims easier to interpret.

Use Search the evidence behind the ingredient profiles. to build better questions before choosing a supplement: what outcome is being targeted, what mechanism is claimed, what human evidence exists, what dose was studied, and what risks could change the answer for a specific person?

Mechanistic plausibility is useful, but it should be weighed against trial design, safety history, product quality, and the possibility that a simpler intervention may be more appropriate.
