Nutrition & Vitamins
Are your supplements
actually working?
Most people never find out. A blood test settles it — what you're genuinely low in, what's already optimal, and what you can stop paying for.

Why it matters
Your nutrition shows up everywhere
Your nutrient levels can influence much more than what's on your supplement shelf. From energy and metabolism to skin, hair and how you feel day to day, understanding what's going on inside your body gives you a clearer picture of what you might need.
Skin
Nutrients like vitamin D, zinc and iron play important roles in maintaining healthy skin and normal cell function.
Hair & nails
Iron, zinc, folate and the B vitamins are all involved in normal hair and nail health. Testing helps you understand whether you're getting enough.
Energy
Feeling tired isn't always about getting more sleep. Iron, B12, folate and other nutrients contribute to normal energy-yielding metabolism.
Metabolism
Your body relies on a range of vitamins and minerals to support normal metabolic processes. Looking at them together gives a broader picture than testing one at a time.
Mood & focus
Nutrition plays a role in normal nervous-system function. Looking at key nutrients can help you understand another piece of the puzzle behind how you feel.
Immunity
Vitamin D, zinc, iron and other nutrients contribute to normal immune function. Testing can help identify where your levels sit.

Looking for zinc? It's analysed by an external UKAS-accredited laboratory on a 5-working-day turnaround, so it sits outside the same-day panel — order it separately here. (Zinc price and SKU pending — see outstanding items.)

Nothing goes wrong on its own.
Low iron turns up next to low B12. Vitamin D sits alongside thyroid and bone markers. Seeing them together tells you far more than testing one at a time.

Questions
Before you book
How is the blood taken?
All our nutrition panels use a venous blood draw — taken from the arm by a trained phlebotomist. You can attend a clinic or book a home visit. We don't use finger-prick collection for these panels, because venous samples give more reliable results across a wider range of markers.
Do I need to fast?
For the core nutrition markers — vitamin D, B12, folate, magnesium, iron and ferritin — no fasting is needed, and you can take your test at any time of day. If your panel includes the lipid profile, we recommend a 10–12 hour water-only fast so cholesterol and triglycerides read cleanly (an early-morning appointment is easiest). HbA1c is a three-month average, so it doesn't require fasting. Whatever combination you build, your confirmation email spells out the exact preparation for the panel you've ordered.
Should I stop my supplements first?
Some supplements can affect results — biotin in particular can interfere with certain assays, and recent B12 supplementation can raise your reading. We'll send specific guidance with your booking. If a supplement has been prescribed for you, don't stop it without speaking to whoever prescribed it.
How quickly do I get results?
Most nutrition markers are reported within 24 hours of the sample reaching the laboratory. A small number of specialist markers — zinc among them — are analysed by an external UKAS-accredited laboratory and take around 5 working days. If your order includes one, we'll tell you at booking.
Who analyses the sample?
Your sample is analysed by our UKAS-accredited partner laboratory, Bloods UK. Results are reported against established reference ranges, and every report is reviewed before release.
Is it cheaper to build my own or buy a panel?
It depends how many markers you want. Building your own gets you your highest-priced marker at full price and everything after at half price. Once you're past four or five selections, one of the ready-made panels usually works out better — and they already group the markers that are worth reading together.
What happens if something comes back outside range?
Your report flags any result outside the reference range and explains what that marker measures. It isn't a diagnosis. If anything needs following up, we'll say so clearly and recommend you speak to your GP or book a consultation.

"Used the service 4 times and have nothing but good things to say. Rare to be able to get a phlebotomist to your house, on this occasion at the weekend as well! Fast and in-depth results, far greater than what we in the UK would get publicly. Staff are all hyper communicative and friendly too, couldn't recommend enough."
