A supplement label tells you everything you need to judge quality — once you know what to look for. Here's a quick guide to reading one like a pro.
Check the serving size
Nutrient amounts are listed per serving, so first see how many capsules or scoops make a serving. Two products can look similar until you notice one needs three capsules to match the other's one.
Look at %NRV
NRV (Nutrient Reference Value) shows how much of your daily reference intake a serving provides. It helps you compare products and spot whether an amount is meaningful or just a token sprinkle.
Read the ingredient list
Ingredients are listed by weight. A short, clear list with recognisable nutrients — like our Simple Multivitamins — is usually a good sign. Watch for lots of fillers or hidden sugars in flavoured products.
Understand the claims
In the UK and EU, only approved health claims can be used — phrases like “contributes to normal immune function.” Vague promises without specifics are a red flag.
Frequently asked questions
What does “high strength” actually mean?
It's a marketing term, not a regulated one — always check the actual amount and %NRV per serving.
Are more ingredients better?
Not always — meaningful amounts of the right nutrients beat a long list of tiny doses.
