Safety
How to use this site safely, and where to get real medical help.
1. This site is not medical advice
Everything on Works for Us - ratings, ranges, stories, comparisons - comes from community reports and published research summaries. It describes what other people experienced. It cannot tell you what is safe or effective for you, because it does not know your health history, your other medications, or your diagnosis.
2. Talk to a qualified clinician first
Before starting, stopping, or changing any supplement, medicine, or treatment, speak to a qualified healthcare professional who knows your situation - your GP, a pharmacist, or a specialist. Pharmacists can often answer supplement and interaction questions quickly and without an appointment.
Bring what you learn here as questions, not as a plan. "People taking X for Y report this - could it be relevant to me?" is a great conversation to have with your clinician.
3. Suspected side effects: report them officially
If you suspect a medicine, supplement, or herbal product has caused a side effect, report it to the UK's regulator via the MHRA Yellow Card scheme. Anyone can report - you do not need to be certain that the product caused the problem, and you do not need a doctor to report on your behalf. Yellow Card reports are how unsafe products get identified and withdrawn.
You can also log the side effect in your Works for Us report - community data helps others spot patterns - but a community report is never a substitute for an official one.
For any serious or worrying reaction, contact NHS 111 or your GP straight away (see below).
4. Emergencies and urgent help
- Call 999 if someone has a severe allergic reaction (anaphylaxis), difficulty breathing, chest pain, or any life-threatening emergency.
- Use NHS 111 (online at 111.nhs.uk or by phone) for urgent but non-life-threatening medical advice, including suspected poisoning or reactions that worry you.
- Contact your GP for non-urgent concerns, ongoing symptoms, or questions about your current treatment.
5. Interactions and combinations
Supplements and medicines can interact with each other, with prescribed drugs, and with existing health conditions. This site may show what people report taking together, but it does not check interactions for you and does not endorse any combination. Ask a pharmacist or doctor about interactions that apply to your situation before combining anything.
