Find out if you are deficient in this vital vitamin with a simple vitamin D blood test carried out using a finger prick kit in your own home.
Vitamin D is essential for maintaining strong bones, but there is growing evidence that it also plays key roles in boosting your immune system, muscle function, energy levels and reducing inflammation to name but a few.
As the main source of vitamin D is sunlight, it is estimated that up to half of all adults in the UK could be deficient in this essential vitamin.
Our vitamin D deficiency test kit makes checking your levels privately, fast, affordable and convenient.
There are several potential symptoms of a vitamin D deficiency, including lethargy and generally lacking in energy.
By taking a simple finger prick blood test to check your vitamin D levels, you can easily identify any deficiency and then, more importantly, take the necessary steps to address it, usually by taking supplements. The impact these changes then make to your numbers can be tracked through your online personal health dashboard.
By eradicating a vitamin D deficiency, you could enjoy benefits including improved energy levels, a reduced risk of bone injuries and an improved immune system.
