Buying supplements from China: what to check
Get the seller’s identity, full ingredients, amounts and batch details before paying. Check any relevant UK medicine or novel-food authorisation and discuss suitability with a pharmacist if you take medicines, have a condition or want a high dose. For label photographs and supplier enquiries in China, ask Cambridge China Bridge.
Trace the seller and the actual product
Ask for the seller’s business name, physical address and working contact details, plus the manufacturer’s name and production address. Match these against the invoice and packaging. Save the listing and messages. Ask who handles complaints about the batch you receive; a marketplace shop name alone leaves that question unanswered.
Request photographs of the actual sealed retail pack, its batch identifier, expiry information and storage instructions. Avoid loose powders or repacked capsules whose original manufacturer and batch cannot be established. If the seller supplies a laboratory report, match it to the product and batch using our food batch certificate guide.
Build an ingredient sheet before choosing
Obtain the complete label and an English translation. Record each ingredient, its form, amount per serving and recommended daily intake. For vitamins, distinguish the nutrient amount from the weight of its compound. For protein powders, identify the protein source, allergens, sweeteners and added stimulants. For herbs, ask for the botanical name, plant part and whether it is a powder or extract.
Ask for individual amounts where a blend hides them. Put your existing supplements alongside the proposed product so a pharmacist can review overlapping ingredients. Identify whey, milk powder, gelatine and other animal ingredients separately. Use our personal food parcel guide to check the destination and postal route rather than assuming that a supplement label settles import questions.
Check which UK authorisation question applies
Ordinary food supplements generally do not undergo prior product approval; genetically modified or novel foods are exceptions. Treat a seller’s claim of UK approval as a request for the exact official record. For a potentially novel ingredient intended for England, Scotland or Wales, check the Food Standards Agency’s novel-food authorisation register and its conditions against the ingredient and proposed use. For Northern Ireland, seek a destination-specific check.
A supplement claiming to prevent, treat or cure disease may be classified as a medicine: ask the Medicines and Healthcare products Regulatory Agency for advice. If a herbal medicine claims traditional herbal registration, compare the exact product with the agency’s published list, rather than accepting a logo photograph. Use our personal medicine guide for the separate seller and import checks.
Consult a pharmacist before paying
Show a UK pharmacist the ingredient sheet, label photographs, intended use and your current medicines and supplements. Seek advice before buying if you are pregnant, breastfeeding, have a medical condition or take prescribed medicines. Ask whether the product is suitable, whether ingredients interact and whether a familiar UK product would meet your needs.
If considering a high dose, obtain advice from your GP or healthcare specialist before proceeding. Ask the pharmacist to explain any unfamiliar amounts, serving instructions or overlapping ingredients. Put the purchase on hold if the seller cannot supply enough information for that review; do not use a trial dose to resolve uncertainty.

Make the buying decision from the evidence
Proceed only when seller identity, ingredients, relevant authorisation checks and the personal postal route are resolved. Agree the exact product and prohibit substitutions. Keep the invoice, label translation and batch photographs together. Cambridge China Bridge’s staff in China can obtain supplier information and packaging photographs for your review; ask a pharmacist to decide suitability for you.
On arrival, compare the packaging and batch with the agreed evidence before using the product. Follow label instructions. If you feel unwell after taking it, stop and contact a healthcare professional. If the purchase becomes stock for resale, use our UK-brand supplement sourcing guide for the separate business enquiry.
Frequently asked questions
Are supplements from China safe for personal use?
Origin alone cannot answer that. Check the actual seller, ingredients, amounts and batch, resolve the postal route and ask a pharmacist about suitability where needed.
Do vitamins need UK product approval?
Ordinary food supplements generally do not undergo prior approval. Novel or genetically modified foods are exceptions. Ask what the seller’s claimed approval covers and verify the exact record.
How do I check a herbal medicine’s UK registration?
Compare the exact product with the medicines regulator’s published list of traditional herbal registrations. Ask a pharmacist to resolve mismatches; a logo photograph alone should not settle the check.
When should I ask a pharmacist before buying?
Before paying if you take prescribed medicines, have a condition, are pregnant or breastfeeding, or cannot interpret the ingredients. For high doses, obtain GP or specialist advice.
