Editorial Policy
This page explains how we research, write, score and update content on Yu Sleeps, so you can judge how much to trust what you read here.
Our Principles
- Accuracy first. We describe what the evidence shows, including when it is weak or missing.
- Balance. Every product page includes downsides, side effects and alternatives, not just benefits.
- Independence. Commissions never decide our scores or conclusions.
- Clarity. We write in plain language and explain technical terms.
- Safety. We always flag drug interactions and groups who should avoid a product.
How We Research
We use sources in this order of priority:
- Government and public health bodies, such as the NIH Office of Dietary Supplements, the National Center for Complementary and Integrative Health, and the FDA.
- Peer-reviewed research, with systematic reviews and randomized controlled trials in humans given the most weight.
- The product's own label and official website, for ingredients, directions, prices and refund terms. We clearly attribute claims made by the manufacturer.
- Reputable medical and health organizations for general sleep guidance.
We don't rely on other affiliate websites, press releases written as advertisements, or unverifiable customer testimonials.
How We Rate the Evidence
For each ingredient, we use a simple three-level scale, shown as a bar on our pages:
| Rating | What it means |
|---|---|
| Moderate | Several human trials or reviews show a consistent, meaningful effect for sleep |
| Limited | A few small human studies suggest a benefit, but results need confirming |
| Weak | Little or no direct human evidence for sleep, or results are mixed or mostly theoretical |
We don't currently use a "strong" rating for any sleep supplement ingredient, because the research for these products is rarely large enough to justify it.
How We Score Products
Our product score is the average of five categories, each rated out of 5: ingredient evidence, safety and transparency, value for money, ease of use, and refund policy. We explain the reasoning for each category on the review page. Scores reflect our editorial judgment at the time of writing and may change if the formula, price or terms change.
Use of AI Tools
We use AI writing tools to help research, draft and edit some content. Every page is checked and edited by a person before publishing, and facts such as prices, ingredients and refund terms are checked against official sources. AI tools never decide our scores or conclusions.
Updates and Corrections
We review our main pages at least every three months, and sooner when prices, ingredients or policies change. Each page shows the date it was last updated.
If you spot a mistake, please email support@yusleeps.com. We'll check it and correct the page if needed. Significant corrections are noted on the page concerned.
