Values in mg/kg. NT = not tested; c = calculated by us from µg per serving.
“UK seller in our data” means the product has a seller link with a UK shop or UK website (priced in £) in our directory. We have not checked whether EU-only shops deliver to the UK, so they are not counted here, even if they might ship. £ per day = pack price ÷ number of servings at the label dose; protein = pack price ÷ (pack weight × label protein per 100 g) × 25 g. Both calculated by us from the seller price we checked on the date shown; prices can change. € and £ are never converted or mixed. Pb = lead, Cd = cadmium, Hg = mercury, As = total arsenic, in mg/kg, copied from each lab report; “<” = below the lab’s reporting limit; NT = not tested; “Pass (no value)” = the certificate states compliance without a measured figure. EU 2023/915 limits for food supplements (also applied in Great Britain): Pb 3.0, Cd 1.0, Hg 0.10 mg/kg; there is no EU limit for arsenic in supplements.

FAQ
Which lab-tested protein powders can I buy in the UK?
Eight Lab verified protein powders have a UK seller in our data. Cost per 25 g of protein (calculated, prices checked 17 Oct 2026): Sunday Natural Vegan Creamy Protein 3K £0.80 and Organic Protein 12K £0.87 (UK website, ships from Germany), Hero Pro Whey Protein Isolate £1.21 (UK company), SFD Nutrition WPC 80 via Allnutrition UK £1.36 (ships from Poland), Form Nutrition Pureblend £1.62 and The Organic Protein Company Organic Whey Protein Pure £1.64 (UK companies), and Puori PW1 £2.46 and Puori PB £3.20 (Danish company with a UK shop). In the whey reports for Hero Pro, SFD and The Organic Protein Company, lead, cadmium and mercury were all below the lab’s reporting limit.
Is there a lab-tested creatine sold in the UK?
Yes, three: Hero Pro 100% Pure Creatine 1000g (about £0.11 a day at 5 g; Eurofins Polska, Apr 2024, lead 0.012 mg/kg), Sunday Natural Creatine Monohydrate Creavitalis 500g on sunday-natural.co.uk (about £0.27 a day at the 3.4 g label dose; GBA Hamburg, Apr 2026, all four metals below the reporting limit) and Hero Pro 100% Creatine Creapure 300g (about £0.32 a day at 5 g; Eurofins Polska, Apr 2025, all four metals <0.005 mg/kg). Hero Pro (London) is the only UK company; Sunday Natural is German. For a like-for-like cost per 5 g, see our cheapest lab-tested creatine page.
What does “UK seller in our data” mean? Does everything else not ship to the UK?
It means the product has a seller link in our directory to a UK shop or a UK version of the brand’s website, priced in £. We have not checked delivery to the UK for every EU-only shop, so a product without a UK seller here may still ship to the UK; we just can’t confirm it. Some UK websites belong to EU companies (Sunday Natural, Puori, SFD Nutrition via Allnutrition UK), so orders may ship from the EU: check delivery time and any import charges at checkout.
Which UK options have the most caveats?
Reports 18 months old or more: Hero Pro 100% Pure Creatine 1000g (Apr 2024), Form Pureblend and Black Rock shilajit (Feb 2025) and Hero Pro Creapure 300g (Apr 2025); PlantPills spirulina and chlorella (Jun 2025) and Blu Brain (May 2025) are about 17 months old. Pass/fail only, no measured values: Together Health KSM-66 (lab not named) and Sunday Natural Bio Ashwagandha KSM-66 Royal. No batch number: all five Ancient + Brave products and Black Rock. Blu Brain’s certificate is transcribed by the brand. Alpha01 Liposomal C has no arsenic result. Highest results: Ancient + Brave Cacao + Collagen cadmium 0.7 mg/kg (70% of the EU limit) and Ayor Health shilajit total arsenic 2.439 mg/kg (no EU limit for arsenic). Every product row lists its red flags.
Which categories have no UK option?
Psyllium husk: our only Lab verified psyllium (Bioptimal) has an EU seller only. Five categories have just one UK option: magnesium glycinate (CLN Labs), fish oil (Bare Biology Life & Soul), L-theanine (Everyday Supplements), liposomal vitamin C (Alpha01) and methylene blue (Blu Brain). Another 15 categories in our directory (for example CoQ10, vitamin D3 + K2, NAC, taurine and zinc) have no Lab verified product from any seller yet.
How do you calculate the £ prices?
Per day: pack price ÷ number of servings at the label dose, for example CLN Labs £8.99 ÷ 30 days (120 capsules at 4 a day) = £0.30. Protein: pack price ÷ (pack weight × label protein per 100 g) × 25 g, for example Hero Pro Whey Protein Isolate £70.49 ÷ (1800 g × 81%) × 25 g = £1.21. We only show a £ price where we checked a UK seller’s price ourselves (16–22 Oct 2026); a few products show “No checked £ price yet”. We never convert € to £ or mix them.
What if I’m in the EU or Spain?
Every category on this page links to its full comparison, where EU sellers are listed separately in €. Examples of Lab verified EU options: HSN RawSeries creatine 200 mesh (Spain, about €0.067 per 5 g), HSN magnesium bisglycinate powder (Spain, about €0.15 a day) and OstroVit Pea Protein Isolate (€0.45 per 25 g protein; out of stock when we checked). The Spanish version of this page is at /es/best/suplementos-analizados-laboratorio-reino-unido.
Is there a legal heavy-metal limit for supplements in the UK?
Yes. Great Britain applies the same maximum levels for food supplements as EU Regulation 2023/915: lead 3.0, cadmium 1.0 and mercury 0.10 mg/kg. There is no limit for arsenic in supplements. Every measured result on this page is within these limits. This page is not medical advice: if you are pregnant, take medicines or have a health condition, ask a pharmacist or doctor before taking a supplement.
