How we select, evaluate, and stand behind everything published on CreusLife.
CreusLife exists to help people make better health decisions through measurement, interpretation, evidence, and practical optimization. We are not a supplement affiliate site. We are a health decision platform organized around a single principle:
Measure first. Optimize second.
Every page on CreusLife starts with a measurement question, not a product recommendation. Our editorial sequence is:
We identify the biomarker, metric, or functional test most relevant to the stated goal.
We explain reference ranges, limitations, and what the evidence says about clinical significance.
We apply our evidence hierarchy (see Evidence Standards). We do not recommend interventions without a measurement rationale.
Every recommendation closes with a retest plan. Without a retest, it's not optimization — it's guessing.
We use three explicit evidence tiers on every supplement and intervention recommendation. See our full Evidence Standards page for the complete hierarchy.
Some links on CreusLife generate affiliate commission. Our editorial recommendations are made independently of these relationships. We recommend products we would recommend without commission, and regularly recommend non-affiliated options when they are the better fit. See our full affiliate disclosure.
