The BetterYou Vitamin D Deficiency Test Kit makes it easy to check your vitamin D levels at home with a simple finger-prick blood test. Accurate lab analysis provides clear results within 10 days, helping you take control of your health and make informed supplementation decisions.

  • Vitamin D plays a critical role in immunity, bone health, and mood — yet deficiency is common, especially in the UK.
  • Identify Deficiency or Insufficiency: Clinical studies highlight the need to maintain our Vitamin D levels through supplementation through-out the year - and especially during the autumn/winter months.
  • Tailor Your Supplementation: Test results allow you to optimise your dosage based on accurate, personalised results.
  • Trusted Lab Analysis: Results provided by a UKAS-accredited UK laboratory, ensuring clinically accurate results.
  • Clear Action Plan: Includes expert advice and BetterYou supplement recommendations, so you know exactly what you need to support your levels.

Testing is the most reliable way to know if you're getting enough Vitamin D. Our test kit is quick, convenient, and comes with the reassurance of expert support.


Fast, easy, confidential


Just a simple finger-prick sample — no need for GP visits or lab appointments.


Your personalised report is emailed securely within 10 working days


Your test kit includes a free Vitamin D oral spray. Following your test results, you’ll receive a discount code to claim your oral spray — supporting your journey to optimal Vitamin D levels.


Free supplement offered based on your results


After testing, you'll receive a free BetterYou Vitamin D spray — because knowing is only the first step.

Your results will show whether your Vitamin D levels are low, insufficient or optimal, along with clear guidance on what to do next and recommended supplementation levels.

Vitamin D daily strengths for adults include:

D1000: Maintenance dose
D3000: High strength dose
D4000: Max strength dose

Vitamin D daily strengths for children include:

D400 Infant: Maintenance dose

You may benefit from testing if you experience fatigue, frequent illness, or spend limited time outdoors. It can be hard to get enough Vitamin D from sunlight and diet alone. Testing allows you to understand what strength Vitamin D supplement is right for you.

Yes, the Vitamin D test service is suitable for children aged 6 months and over. Children under 6 months should have their Vitamin D levels tested by a GP.

The test kit uses a small finger-prick to collect blood spots for analysis.

For babies and younger children, we recommend using the lancet on the heel of the foot, as it provides a larger surface area and may help reduce discomfort.

Please note, the test should be purchased by an adult/guardian aged 18 or over, and the sample must be collected by an adult or guardian.

The blood spot kits measure 25-hydroxyvitamin D, which reflects body Vitamin D stores. This is generally accepted to be the most useful indicator of Vitamin D status.

The active form is 1,25-dihydroxyvitamin D but this is only measured in very few, rare clinical situations. It is also very unstable and difficult to measure so only a few labs in the country do actually measure it.

There is no right or wrong answer to this. If you are currently taking a Vitamin D supplement and want to check the impact of your supplementation routine, then you can take the test straight away.

However, if you’re looking to discover your ‘baseline’ Vitamin D levels (diet and lifestyle alone), then we would recommend a ‘wash-out’ period of 4-6 weeks, as this is around how long 25(OH)D (Vitamin D) stays in the body.
