Supplement Recalls in the UK: How Contaminated Products Get Caught and How to Check

In the UK, a business that finds its supplement is unsafe must withdraw it from sale and, if customers have it, recall it. The Food Standards Agency (FSA) publishes alerts so you can identify affected products. To check a supplement, search the FSA's alerts, sign up for free email or text alerts, compare batch codes, and report concerns to your local council.

This guide explains how the system works and what recent alerts and surveys found. For the bigger picture on choosing a product, see how to verify supplement quality in the UK.

Who is responsible when a supplement is unsafe?

The business selling it. In the UK, food supplements are regulated as food, not medicines, and food that's unsafe can't be placed on the market. Under Article 19 of retained General Food Law, a food business that believes its food is unsafe must start withdrawing it and tell the authorities; if it may have reached consumers, it must tell them why and recall it if needed.

The difference is simple: a withdrawal removes unsafe food before it reaches consumers, and a recall asks consumers who have it to take action. Local councils enforce the rules through Trading Standards and Environmental Health. If a product claims to treat illness or contains a medicine, it may be a medicine, regulated by the Medicines and Healthcare products Regulatory Agency (MHRA).

What types of alert does the FSA issue?

• Product Recall Information Notice (PRIN): issued when a product is being recalled, to tell consumers and councils about the problem.

• Allergy Alert: issued when allergy information on a label is missing or wrong.

• Food Alert for Action (FAFA): issued when councils need to step in, with specific actions for them.

In Scotland, Food Standards Scotland publishes alerts.

What recent supplement alerts have there been?

Supplement recalls do happen, and they're not limited to obscure products. Recent examples include:

• Vitamin D3 drops, January 2025: high levels of vitamin D3 were found in oral drops and solutions, and the FSA warned that excessive vitamin D intake can cause harm through high blood calcium.

• Eggshell membrane capsules, June 2025: capsules sold through an online marketplace were recalled because of Salmonella, with advice not to eat them. Food Standards Scotland later linked the contamination to illness.

• Children's multivitamin gummies, February 2023: an allergy alert for undeclared soya.

• Sports nutrition powder, July 2023: recalled because of high caffeine levels.

What do FSA surveys find?

Recalls only show problems that someone has caught. FSA sampling surveys give a broader picture:

1. Ashwagandha supplements: in the FSA's 2025/26 retail survey, 85% of 40 samples had unsatisfactory results. Two exceeded the legal limit for cadmium and three had high aflatoxin levels; labelling problems were the most common issue.

2. Green powder supplements: in the same survey, five of 40 were unsatisfactory, and two contained a food colour not permitted in supplements.

3. Caffeine supplements: an earlier FSA survey found 83% of samples unsatisfactory, mainly because caffeine content didn't match the label.

An unsatisfactory result doesn't always mean an immediate health risk; it can be a labelling or compliance failure. But it shows why independent testing of what's actually in the product matters.

How can you check if a supplement has been recalled?

• Search the FSA's alerts: current recalls and allergy alerts are listed with product names, batch codes and dates.

• Sign up for free alerts by email or text, and choose which allergens you want to hear about.

• Compare the batch code and best before date on your pack, as alerts usually apply to specific batches.

• Follow the advice in the alert, which usually means stopping use and returning the product for a refund.

How do you report a problem with a supplement?

The FSA's consumer guidance on food supplements says to report safety issues to your local council, which passes incidents to the FSA. Report misleading or incomplete labels to Trading Standards. If you've had a side effect you think a supplement caused, speak to your GP or pharmacist, and you can report it through the MHRA's Yellow Card scheme.

How can you lower your risk?

The same FSA guidance advises buying online only from businesses you're confident are reputable, taking extra care with online marketplaces, reading labels and warnings, checking that health claims are authorised, and not exceeding the recommended dose.

Two further checks are worth adding, and both are free:

1. Check the brand is a registered food business. Search its name on the FSA food hygiene ratings site; a legitimate UK supplement seller should be registered with its local council.

2. Check it publishes independent lab results from a named laboratory, and what those results cover. See third-party tested and self-certified supplements and what UKAS accreditation actually covers.

How NovusDNA checks out

NovusDNA is a UK supplement brand making clearly labelled, science-led supplements tested by Campden BRI, a UKAS-accredited UK laboratory. Here's how it does against the checks above:

• Food business registration: Novus DNA is listed on the FSA ratings site, registered with Preston City Council. At its inspection on 3 December 2025, hygienic food handling and the cleanliness of facilities were rated very good, and management of food safety was rated good.

• Independent testing: products are tested by Campden BRI, UKAS accredited testing laboratory No. 1079, with summaries published on product pages. Essential+, NovusDNA's daily D3, K2 and magnesium formula, for example, reports vitamin D3, K2 and magnesium content, with Salmonella not detected and yeast, mould and coagulase-positive Staphylococci each below 10 cfu/g. Given the vitamin D drops recall above, testing the actual vitamin content, not just contaminants, is exactly the kind of check that matters.

• Where to buy: direct from novusdna.com, with full certificates available on request from info@novusdna.com.

Testing can't eliminate every risk, but it makes problems far more likely to be caught before a product reaches you.

FAQ

How do I know if a supplement has been recalled in the UK?

Search the Food Standards Agency's alerts website, which lists current recalls and allergy alerts with product names and batch codes, and sign up for free email or text alerts. In Scotland, Food Standards Scotland publishes alerts.

Who regulates supplements in the UK?

Food supplements are regulated as food. Local councils enforce the rules through Trading Standards and Environmental Health, and the Food Standards Agency coordinates food alerts. If a product counts as a medicine, the MHRA is responsible.

Are supplements tested before they go on sale in the UK?

Not routinely. Most food supplements don't need pre-market approval, although novel foods and some ingredients do need authorisation. Businesses are legally responsible for making sure their products are safe and correctly labelled, and councils and the FSA sample products, but not every product is tested. That's why brands that publish independent lab results are worth seeking out.

What should I do if my supplement has been recalled?

Follow the advice in the alert, which usually means stopping use and returning the product to where you bought it for a refund. If you feel unwell, speak to your GP or call NHS 111.

How do I report a potentially unsafe supplement?

Report safety concerns to your local council's food safety team, which will pass incidents to the FSA, and report misleading labels to Trading Standards. If you suspect a product contains a medicine, or you've had a side effect, report it to the MHRA through its Yellow Card scheme.

The UK supplement recall system relies on businesses acting quickly and on people reporting problems. Sign up for FSA alerts, buy from registered UK sellers, and choose brands that publish independent test results.
