Evaluate a health claim before sharing it
Look for a source, a defined outcome, and a fair comparison.
A confident headline can travel farther than the evidence behind it. Before sharing a health claim, separate what is being promised from what was actually studied. You do not need to become a researcher to ask a few useful questions.
Write down the exact claim
Does the post promise to prevent a disease, relieve a symptom, or improve a vague measure of wellness? Ask who the claim applies to and what result is being measured. “Supports health” is too broad to evaluate without an explanation.
Follow the evidence trail
Look for the original study or a reliable public-health explanation. A testimonial describes an experience, not a controlled comparison. If the evidence is about animals, a different population, or a different dose, it may not support the product’s claim for you.
Check the incentives
Notice whether the author sells the product, receives a referral payment, or links to a paid program. A financial interest does not automatically make a statement false, but it increases the importance of independent support. Pause when a post combines urgency, secrecy, and a purchase button.

- Identify the exact promised result.
- Find the original evidence or independent explanation.
- Check who benefits from a sale.
