Independent Research
Editorial Policy
How Yu Sleep Research sources, writes, updates and separates product claims from independent evidence.
Source hierarchy
- Current product label.
- Current vendor and checkout information.
- Vendor policy/support pages.
- NIH, FDA and other federal health resources.
- PubMed-indexed and peer-reviewed research.
Evidence separation
Vendor statements are identified as vendor-reported. Ingredient research is not presented as finished-product proof unless a finished-product trial is available and directly supports the claim.
Corrections and updates
Commercial information is time-sensitive. Pages display a last-updated date and should be rechecked when the seller changes its offer or label.
