Most people think they’re getting enough vitamin D. A bit of sun here and there, maybe a supplement in winter, job done. But in reality, worldwide, vitamin D deficiency is incredibly common, especially in countries like the UK where we spend months with weak sunlight, long evenings and a lot of time indoors.
The Zinzino Vitamin D Test takes away the guesswork. It’s a simple at-home finger-prick blood test that shows you exactly where your levels are right now and whether you might need extra support.

What is the Zinzino Vitamin D Test?
This is an at-home dried blood spot (DBS) test, where you place 1–2 drops of blood from your fingertip onto special filter paper. The sample is then analysed by Vitas Analytical Services in Norway – a GMP-certified lab with 25+ years’ experience in high-precision blood analysis.
The test measures 25-hydroxyvitamin D [25(OH)D], which is the best and most widely accepted marker of vitamin D status in the body. It reflects vitamin D from three sources – food, supplements and sunlight – so you get a complete picture of your overall status.
Your results are presented in an easy-to-understand online dashboard and summarised visually so you can instantly see if your levels are too low, within range or optimal.
Why Vitamin D Matters
Vitamin D is often called the “sunshine nutrient” – but it’s actually a hormone-like vitamin involved in so many body systems. It:
Supports normal immune function
Helps the body absorb and use calcium, supporting bones and teeth
Contributes to normal muscle function
Plays a role in cell division and overall cellular health
In the UK, our vitamin D levels naturally fluctuate across the year depending on sun exposure, where we live, our skin type, clothing, sunscreen habits and how much time we spend outdoors. For many people, food alone isn’t enough to maintain optimal levels all year round.
That’s why testing regularly – rather than guessing – is so powerful.
What You Actually Get From the Test
When your results are ready, you receive:
Your current vitamin D level (in nmol/L or ng/mL)
An indication if your levels are too low, normal or optimal
Clear, visual graphs showing where you sit on the scale
Personalised recommendations on how to maintain or improve your levels, including suggested intake and lifestyle tips
Guidance that can be paired with ZinoShine+ (vitamin D3 + magnesium) if you choose to supplement
Most clients repeat the test roughly every 120 days to track their progress and adjust for seasonal changes.
How It Works – Step by Step

In around 10–20 days, your results appear online with personalised guidance.
There’s no need to visit a clinic, no large blood draw, and no complicated lab printouts you can’t interpret.
Who This Test is Especially Helpful For
People who feel tired, low, or “run down” in autumn and winter
Those who work indoors or hardly see direct sunlight
Darker skin tones (who naturally produce less vitamin D from the same sunlight)
Those who cover up for cultural or skin reasons
Anyone with bone, muscle or immune concerns who wants more data
Clients wanting a baseline before starting ZinoShine+

Vicky’s Take
I love the Vitamin D Test because it’s so simple, but the information is powerful. It shows you exactly where you stand, not where you assume you are. From there, we can build a personalised inside-out plan – often combining ZinoShine+, BalanceOil+ and lifestyle tweaks – to help you feel stronger, brighter and more resilient through the seasons.
