Non-GMO Supplements

What does non-GMO mean on a supplement?

"Non-GMO" is the manufacturer's statement that a product isn't made from genetically modified organisms (GMOs). It isn't a certification in itself, and different brands may verify it in different ways, so check the label for how the claim is backed up, such as a named third-party scheme.

Products appear in this collection because they are listed as non-GMO by the manufacturer. We haven't independently tested them.

What are the GM labelling rules in the UK?

In England, Wales and Northern Ireland, the Food Standards Agency says foods must be labelled if they contain or consist of GMOs, or contain ingredients produced from GMOs, including flour, cooking oils and glucose syrups from a GM source.

Foods produced with the help of GM technology don't have to be labelled, such as cheese made with GM enzymes, and the FSA says meat, milk and eggs from animals fed on GM animal feed also don't need to be labelled. So the absence of a GM label doesn't tell you everything about the supply chain, which is why some manufacturers make a separate non-GMO statement.

Is non-GMO more important than the dose?

It's one factor, not the main one. A non-GMO statement tells you about sourcing, not how much of each ingredient you get or what it costs per day, so compare those first.

"My biggest takeaway from sourcing these products is that customers need more transparency, not more marketing claims," says Andy Arshad, who runs SupplementHQ. Our guide to reading a supplement label explains how to compare the amounts.

We sell the products on this page. That's our commercial interest, and it's why we show the evidence alongside them. This page is general information for adults, not personalised medical advice. Food supplements should not replace a varied, balanced diet.
