By using a BetterYou at-home health check you get to see an accurate insight into your levels of a specific nutrient, along with a detailed supplementation plan to help you maintain or elevate your levels for optimal health.

We will also provide you with a complimentary oral spray to help you kick-start your journey to optimal health, all included in a single one-off price.

Your results will be analysed by SureScreen Health, a UKAS-accredited laboratory based in the UK.

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.
