A practical starting point
Write down the claim first. “Contains a researched ingredient” and “this product improves walking” are different statements. Then identify the source: label, laboratory experiment, human trial, review article or testimonial.
For a trial, check the exact preparation, daily dose, participants, comparison group and duration. Read the outcome measured rather than inferring one from a mechanism. Look for adverse events and the size of the effect, not just whether the authors report statistical significance.
Ask whether the formula in your bottle matches the tested material. A combined capsule may differ in dose, excipients or route. A good review acknowledges those differences and does not treat a missing link as established fact.

Read more than the abstract conclusion
Where full text is accessible, look at participant selection, missing data, comparator, funding and whether the outcome was chosen before the results were known. If only an abstract is available, say so and keep the claim narrow.
A reference list is useful only when readers can see which statement each source supports. This site’s source register records the role and limitations of the references used. It is a focused review, not a systematic review of every paper.
