How to Read a Supplement Label Properly

Food and supplement labelling in the EU is tightly regulated in some places and wide open in others. Knowing which is which turns a label from decoration into information. Here is how to read one.

1. Ingredients are listed by descending weight

This is legally required and it is the single most useful line on any pack. The first ingredient is the largest component by weight, the last is the smallest.

Apply it ruthlessly. If a product is sold on the strength of one hero ingredient and that ingredient appears fourth, after a bulking agent and two fillers, the front of the pack and the back of the pack are telling different stories. Believe the back.

2. "Proprietary blend" means you are not being told

When several ingredients are grouped under a blend name with a single combined weight, the individual quantities are hidden. A 500 mg blend could be 480 mg of the cheapest component and 20 mg of everything else, and the label would be entirely accurate.

Occasionally there is a legitimate formulation reason. Far more often it conceals under-dosing of the expensive ingredients. Treat it as missing information, because that is what it is.

3. Extract ratios and what they mean

You will see notations like 4:1 or 10:1. This means the stated weight of raw plant was reduced to one part of extract — 10:1 means ten kilos of plant produced one kilo of extract.

A higher ratio is not automatically better. It tells you about concentration, not about which compounds were concentrated or whether the ones that mattered survived the extraction solvent and heat. Ask what was standardised to, not just how concentrated it is.

4. Percentage NRV

NRV — Nutrient Reference Value — is the EU reference intake for vitamins and minerals. A label showing 80% NRV for vitamin C tells you the serving provides 80% of that reference figure.

NRVs are population-level reference points, not personalised targets. And extremely high percentages — several thousand percent — are a marketing signal more than a nutritional one; for water-soluble vitamins the excess is largely excreted.

5. Regulated words versus free words

These carry legal weight and can be verified:

• Organic / Bio — certified, with a control body code on the pack.
• Authorised health claims — only specific approved wordings tied to specific nutrients at specific doses may be used under EU Regulation 1924/2006. Anything promising to treat, cure or prevent a disease is not permitted on a food at all.

These carry no legal definition and can be printed by anyone:

• Natural, pure, premium, traditional, artisanal, superfood, wild-harvested, ancestral, detox.

None of those words is a lie. None of them is checkable either.

6. Country of origin

Look for a specific country or region. "Packaged in France" tells you where a machine filled the pouch, not where anything grew. "EU / non-EU agriculture" on organic products is the vaguest legal formulation permitted — and it is used when a brand does not want to say.

7. Contact details and batch codes

A named company with a real address and a batch code is a company that can be held responsible. A brand name with a PO box and no batch information is a company that cannot.

The one-minute version

Read the ingredient list first and ignore the front. Check where the hero ingredient sits in the order. Look for a named origin. Look for a batch code. Treat unregulated adjectives as decoration. That takes a minute and it will change what you buy.
