Methodology
How we build recommendations
Transparency about what's behind every timing chip, pairing badge, and spacing warning on this site.
Source hierarchy
We prioritize peer-reviewed clinical trials (RCTs, meta-analyses) on PubMed, followed by NIH ODS fact sheets, then well-cited review articles. Anecdote and supplement-brand marketing are not used as primary sources.
Conflict resolution
When sources disagree, we default to the most conservative recommendation and surface the disagreement in the FAQ. Where evidence is genuinely thin (e.g. some adaptogens), we say so plainly rather than picking a side.
Scope of advice
OptimalNourish only addresses timing, food pairing, spacing, and form factor. We never recommend dosages, treat conditions, or replace a clinician. Caution flags surface when a supplement interacts with common medications or conditions.
Editorial review
Every supplement page is reviewed quarterly. Citations are dated; if a source is older than 10 years and a newer high-quality study exists, we replace it.
What we don't do
We don't sell supplements, don't take affiliate commissions on brand recommendations, and don't run sponsored content.
