SKINCARE, SUPPLEMENTS AND BLOOD TESTS, CHOSEN BY A NURSE

The Muhdo kit in our shop is a saliva test, so there's no blood draw. Your kit has what you need to give a saliva sample, which you return for laboratory analysis. Your results appear in the MuhdoHub app, which includes Muhdo's AI health coach. The results are health and wellness information and should not be treated as a medical diagnosis.

Most blood tests aren't posted to you: once you've ordered, we arrange your blood draw at our King Street clinic or at a partner clinic near you, anywhere in the UK. If you'd like to check delivery or collection for skincare, supplements or test kits before you order, call us on 07413 138 825 or email office@juvenology.co.uk.

A product page can't tell you whether a supplement suits you, because that depends on your health, diet and any medicines you take. Food supplements shouldn't replace a varied, balanced diet, and you shouldn't take more than the recommended daily dose. If you're pregnant, breastfeeding, taking medicines or have a medical condition, check with your GP or pharmacist first. If you have a blood test with us, you can ask Marina about supplements at your results consultation.

Use it in the evening only, starting two or three nights a week and building up as your skin adjusts. Wear SPF every morning while you use retinol. Some dryness or flaking is normal in the first few weeks. Don't use it if you're pregnant, trying to conceive or breastfeeding, and stop a few days before microneedling, peels, laser or other in-clinic treatments.
