    Importance of checking your vitamin D levels

    Approximately 1 in 5 people within the UK have are low or deficient in vitamin D. 

    With our increasingly indoor existence and changing diets, it’s becoming harder for us to get our required vitamin D from the sun alone

    A test should be considered by everyone as it helps establish if your current lifestyle and diet is providing as much vitamin D as you think it is.

    Who needs it

    While the test is suitable for everyone, people within the Department of Health’s “at-risk” groups should strongly consider checking their levels as they have an increased risk of vitamin D deficiency.

    • All pregnant and breastfeeding women
    • Infants and young children under 5 years of age
    • Older people aged 65 years and over
    • People who have low or no exposure to the sun
    • People who have darker skin
  • Directions

    How to use

    We send the testing kit out for you to use at home. All you must do is place four blood spots onto the collection card from a quick and painless nick of the finger. Full instructions are included in the pack you will receive.

    Using the prepaid envelope, the collection card is then sent to City Assays, who analyse the sample for Sandwell and West Birmingham trust.

    From the spots of dried blood on your sample card, the laboratory at City Assays uses a liquid chromatography mass spectrometry method to measure the Vitamin D in your blood. They measure for Vitamin D2 and D3, reporting the total and D2 and D3 results.

    The results are supplied within 10 working days of the lab receiving your sample.

    The results are emailed directly to you and BetterYou. From this, we will provide you with a bespoke supplementation plan to help increase or maintain your levels. You will also receive a discount code for a complimentary DLux Vitamin D Oral Spray relevant to your results, which you can redeem through our website.


    Once opened, store at room temperature and out of direct sunlight.

    Keep out of reach and sight of children.


    This test is not a substitute for seeing a doctor. If you are at all unsure about your results, please consult your doctor or medical professional.

    For extremely low or high levels, a member of the Sandwell and West Birmingham Trust will be in contact with you to discuss your results.
