Weight-management supplement claim checklist

1. Identify the exact promise

Write down what the marketing actually says and what a typical reader might reasonably infer. Be cautious with promises of rapid, permanent, effortless, or universal results.

2. Check whether the cited evidence matches

Ask whether a source studies the same finished product, population, dose, duration, and outcome. Evidence about one ingredient does not automatically establish a result for a multi-ingredient product.

3. Look for limits—not just benefits

Check for relevant limitations, study quality, competing explanations, and material safety information. A clear limitation is more useful than a sweeping conclusion.

4. Check the sales practice

Read the full price, shipping terms, renewal terms, cancellation policy, and return policy before sharing payment details. A “free trial” can still create recurring charges.

5. Avoid false authority signals

A logo, a white coat, a dramatic before-and-after image, or an unsupported review is not evidence. Do not treat an online endorsement as proof that a result will apply to you.

6. Use safer next steps

Consider reliable government and clinical information, and discuss supplement use with an appropriate healthcare professional when medicines, symptoms, diagnosed conditions, pregnancy, breastfeeding, or surgery are relevant.
