How Qenph reviews a food supplement
Our methodology explains how we separate manufacturer information, label data, scientific literature, limits of extrapolation and commercial terms.
An important claim should be traceable to a source.
A study on an ingredient is not automatically a study on the product.
What we cannot demonstrate is stated explicitly.
1. Identify the formula currently presented
A supplement can change formula, label, daily serving or ingredient supplier. We therefore start with the official page and the information available on the label. An old formula is not mixed with the current version simply because it still circulates on blogs, forums or cached pages.
For PhenQ and PhenQ PM, this step is especially important because both products belong to the same range but have different compositions and times of use.
2. Separate three types of information
Verifiable facts
- product name and format;
- published composition;
- stated directions for use;
- presence of caffeine or other compounds;
- visible commercial terms.
Claims that need context
- “burns fat”;
- “reduces appetite”;
- “works while you sleep”;
- commercial result percentages;
- extrapolating from one ingredient to the complete formula.
3. Compare dose, form, duration and population
Two studies using the same ingredient name may not be comparable. Chemical form, daily dose, trial duration, age, starting weight, diet and the presence of a control group all affect interpretation. A study using several grams of L-carnitine per day does not automatically validate a formula providing a very different amount.
4. Rank the level of evidence
5. Look for the outcome that actually matters
A change in a biological marker can be interesting without having a noticeable effect on weight or health. Qenph therefore distinguishes effects on alertness, thermogenesis, blood glucose, satiety hormones or sleep from an actual difference in body weight, fat mass or waist circumference.
6. Review safety before conversion
Safety should not be pushed below the purchase button. We look for manufacturer warnings first, then information from health authorities and reliable medical sources about adverse effects, interactions and groups that require extra caution.
7. Do not invent precision
Qenph does not give a supplement a “9.7/10” when the criteria do not allow such an objectively precise measurement. We prefer to explain documentary strengths, limitations, missing data and the difference between what is known about an ingredient and what has been demonstrated for the complete formula.
8. Treat prices as volatile data
Prices, discounts, packs, shipping fees and subscriptions may change without notice. To avoid an old value becoming misleading, Qenph focuses on comparing commercial mechanisms and directs users to the merchant for the current amount.
9. Correct and update
A page may be revised when a formula changes, an institutional source is updated or a factual error is identified. The page Contact allows you to report a correction. Updates focus first on accuracy, not on artificially adding new sentences.
What E-E-A-T means here
Qenph cannot “add an E-E-A-T tag”. Trust is built through verifiable elements: publisher identity, a clear editorial purpose, public methodology, cited sources, separation between advertising and analysis, no fake professional credentials and correction of errors.
