How to read a supplement label and not overpay
2026-06-27 · 5 min read
A flashy tub and loud claims on the front are marketing. A supplement’s real value is on the back: the ingredients, doses and serving size. Learning to read the label means you stop overpaying.
Look at the doses
It is not the presence of an ingredient that matters but its dose. For example creatine needs ~3–5 g, citrulline ~6–8 g. If a “trendy” ingredient is added in a token micro-dose, it does little.
Beware “proprietary blends”
If the label shows only the total mass of a “blend” without each component’s dose, the maker is hiding how much of what is inside. Often this conceals little active ingredient and a lot of cheap filler.
Calculate price per serving
Compare not the tub price but the price per real serving and per gram of active ingredient. Sometimes an “expensive” tub with big doses is cheaper than a “cheap” one with small ones.
FAQ
What matters more — brand or formula?
Both: a trusted brand is a guarantee of quality and purity, while the formula shows what you pay for. Look at both together.
Should I fear a long ingredient list?
Not always. Sometimes it is a complete formula, sometimes many components in uselessly small doses. Look specifically at the doses.
