How to actually read a supplement label
The one section most people skip is the one that matters. A short guide to decoding a bottle in under two minutes.
A supplement label has two jobs: tell you what's in the bottle, and tell you how much of it. Everything else — the front-of-pack claims, the seals, the founder story — is marketing.
Start with the Supplement Facts panel. That's the black-bordered box, usually on the back. Look at serving size first. A 60-capsule bottle at 'two capsules daily' is a 30-day supply, not 60.
Next, compare the amount per serving against the % Daily Value where one exists. Some nutrients (like B12, or many herbs) don't have an established DV — that doesn't mean the dose is meaningless, it just means the FDA hasn't set a reference.
Then check the 'Other Ingredients' line. This is where fillers, flow agents, and allergens live. Fewer is usually better, but not always — some capsule shells or emulsifiers are unavoidable.
Finally, look for a lot number and an expiration date. A brand that publishes these — and, ideally, a certificate of analysis for that lot — is a brand that expects to be checked.
