Vitamin D Test Kit

(At-home blood test)

The Vitamin D Test Kit is a quick and effective blood test you can use to measure your vitamin D levels at home. Vitamin D is crucial for bone health and muscle function, and in the UK about 1 in 5 people have very low vitamin D levels. During the winter, most people have suboptimal Vitamin D levels due to a lack of sunlight.

Each Test Kit comes with a free review from a UK clinician who can offer personalised health advice based on the outcome of your test.
