How to Read Supplement Labels: Dosage, Ingredients, Safety

Reading supplement labels

Why Reading Supplement Labels Matters

Labels tell you the dose per serving, active ingredients, and other compounds. Understanding them helps you avoid overdosing, spot unnecessary additives, and compare products. As a content manager, I recommend checking the Supplement Facts panel, serving size, and any warnings before buying or using any supplement.

Look for standardisation (e.g. percent of active compound), third-party testing seals (USP, NSF, ConsumerLab), and expiry date. Supplements on iHerb and vitamins vary in quality; labels help you choose.

Key Sections on a Label

Supplement Facts: amount per serving, % Daily Value where applicable. Ingredients: full list, including fillers and allergens. Warnings: interactions, pregnancy, or medical conditions. Storage and expiry. Serving size: some products require multiple capsules for the stated dose—check carefully.

Practical Tips

Do not assume more is better; stay within recommended doses. Compare brands by active amount per serving, not just price. When in doubt, consult a pharmacist or doctor. Supplement options on iHerb include many with clear labelling. Store products as directed and discard after expiry.
