Rapid Vitamin D deficiency test

Vitamin D deficiency occurs when the body doesn’t have enough vitamin D — a vital nutrient that supports bone health, muscle strength, and immune function. Vitamin D helps the body absorb calcium and phosphorus, which are essential for maintaining healthy bones and teeth. It also plays an important role in immune regulation and mood balance.

Low vitamin D levels are common, especially in the UK where sunlight exposure is limited for much of the year. When levels drop too low, it can lead to symptoms such as fatigue, low mood, muscle aches, bone pain, hair loss, frequent infections, and poor recovery from illness.

Our Rapid Vitamin D Test takes just 15 minutes and requires only a small drop of blood from a finger prick. We analyse it straight away, giving you an immediate result so you can see whether your vitamin D levels are within the healthy range or if a deficiency treatment may be beneficial.
