How to Read a Supplement Label Like a Pharmacist
Supplement bottles shout about the front and whisper on the back. The back panel — the Supplement Facts box — is where pharmacists look first. Here is how to read it in under a minute.
1. Start with serving size
Every number on the panel is per serving, not per bottle. A bottle of 60 tablets with a serving size of two lasts 30 days, not 60. Always do this maths first — it changes both the dose and the value.
2. Check the % Daily Value
Under 20% is a top-up; over 100% is a full replacement dose. Mega-doses of water-soluble vitamins like C and B mostly end up flushed away, while fat-soluble A, D, E and K can accumulate — more is not always better.
3. Beware the proprietary blend
Blends list a total weight but hide individual amounts, so you cannot tell whether the headline herb is present in a useful dose. Prefer products that state exact milligrams per ingredient.
4. Scan the "other ingredients"
Binders, coatings and colourings sit below the active ingredients. A short list is usually a good sign. If you avoid gluten, lactose or artificial dyes, this is the line that matters most.
5. Look for third-party seals
- Independent testing marks confirm the bottle contains what it claims.
- Batch or lot numbers show the maker tracks quality per production run.
- A real expiry date — not just a manufacturing date — tells you it is stability-tested.
Still unsure? Bring the bottle — or a photo of the label — to our pharmacists through the contact page and we will translate it into plain English.
