Vitamin D levels are commonly low in around 1 in 6 adults in the UK.

The winter months from October to March are more challenging to get sufficient levels due to limited sunlight exposure, cold weather clothing which covers most of the skin and our winter indoor lifestyles.

By testing our levels we can ensure we are taking accurate dosages based on our results.
