What to Check Before Buying a Dietary Supplement

Start with the product category and format. Comparing two bottles by price is not useful if serving sizes, quantities, or intended uses differ.

Review the Supplement Facts panel, other ingredients, directions, warnings, storage instructions, and company information. Save or photograph the label if you need to discuss it with a professional.

Separate a product’s identity from what its marketing suggests. Claims that promise a cure, guaranteed outcome, or immediate result deserve particular caution. Dietary supplements are not approved by the FDA in the same way as prescription drugs before marketing.

• Find a real company name and contact method.
• Read recurring-billing or subscription terms.
• Review shipping costs and timing.
• Read the refund window, exclusions, and return process.
• Keep a copy of the order confirmation.

Calculate price per serving and include shipping or subscription requirements. A lower bottle price can still cost more per serving, and a larger package is not automatically a better value.

Discuss supplement use with a qualified healthcare professional when you are pregnant, nursing, taking medication, managing a condition, planning surgery, or considering a product for a child.
