Before acting on an online health claim, find out who made it and what evidence supports it. A confident video, an attractive website or a large follower count cannot answer those questions for you.
Start with the source behind the headline
MedlinePlus recommends checking who runs a site, its purpose and funding, the quality and date of its information, and how it uses personal data. It advises comparing reliable sources and discussing information with a health professional before relying on it for personal care. Source: MedlinePlus, Evaluating Health Information.
Turn a broad claim into a specific question
“This fixes your hormones” is difficult to evaluate because it does not identify the condition, outcome or people studied. Write down exactly what the claim promises. Does it mean a laboratory measurement changed, symptoms improved, or a disease was treated? Those are different claims.
If the post links a study, follow the link. Check that it actually discusses the product, population and result in the headline. A general paper about sleep does not automatically support a claim about a particular supplement.
A five-question check
- Can I identify the author or organization?
- Is there a direct source I can open?
- Does that source support this exact claim?
- Is the information relevant to the people and situation being discussed?
- Is a purchase, sign-up or personal-data request influencing the presentation?
Write “unknown” beside unanswered questions. Missing information does not prove a claim false, but it is a reason to pause before sharing it as established fact.
Use a fictional example
Imagine a post saying a drink “doubles recovery” and linking only to the seller’s checkout page. Before buying, ask what recovery means, what it was compared with, and where the study can be read. A testimonial from someone who enjoyed the drink does not answer those questions.
If a headline says people who did an activity had better outcomes, check whether the study can actually show the activity caused the difference. Keep the strength of your conclusion proportional to the evidence you can inspect.

Read our sources, dates and editorial disclosures too. Tranquilla Wellness uses AI assistance and does not claim independent clinical review where none has occurred. An educational article can help frame a question, but cannot know your full medical circumstances.
Do not stop or change prescribed treatment because of a post. Save the specific claim and source, then bring a clear question to an appropriate clinician. Sharing the uncertainty is more useful than repeating an unsupported promise.
