A more useful way to read research

Clarity before claims.

People, not promises.

Human trials take priority. Animal studies and biological mechanisms provide context, not proof of benefits for you.

Size matters.

A statistically significant result may still be too small to notice. We look at the size and relevance of the effect.

Uncertainty stays visible.

Study limitations, funding, safety and unanswered questions belong beside the headline.
