1. Confirm the serving size before reading doses
An ingredient amount only makes sense in the context of how many capsules, tablets or milliliters make up a serving. Compare the front-of-bottle promise with the actual Supplement Facts panel.
2. Look for exact amounts
If the product names ingredients but does not disclose meaningful amounts, you cannot compare the formula with doses studied in research. More ingredients is not automatically better.
3. Separate structure/function language from disease claims
Dietary supplements can be marketed with certain structure/function claims, but a supplement represented as treating, preventing or curing a disease crosses into drug-claim territory. Be especially cautious with “replace your medication,” “cure diabetes” or similar language.
4. Read the warning section
Look for age, pregnancy, surgery, allergy and medication cautions. Then ask a pharmacist or clinician about the entire formula—not just the headline ingredient.
5. Check who actually sells and fulfills the order
Return terms, shipping costs and the retailer of record matter. Save a copy of the seller's current return policy and your order confirmation at purchase time.
