How to Read a Supplement Label Without Getting Fooled

Proprietary blends, fairy dusting, third-party seals and refund small print. A short checklist that removes most bad purchases.

Everything useful is on the back

The front of a tub sells; the back informs. Before anything else, find the supplement facts panel and check that each active ingredient has its own number beside it. A label that lists ingredients without individual doses is telling you something, and it is not flattering.

Five red flags

  • A proprietary blend with one combined weight, so no single dose can be verified.
  • Long ingredient lists where impressive-sounding extras appear in trace amounts.
  • Claims of curing, treating or reversing anything — a legal line no honest brand crosses.
  • “Lab tested” with no named third party and no certificate available.
  • A refund policy described only in marketing copy, never in terms you can read.

None of these prove a product is worthless. Together they tell you how much the seller expects you to check.

What good labels do

  • Per-serving doses for every active ingredient, in milligrams.
  • Standardisation stated where it matters, for example catechin content in a green tea extract.
  • A named manufacturing standard and a batch or lot number.
  • A written refund window with a clear address for returns.
You are not judging whether a supplement works. You are judging whether the seller is willing to be checked.
