Vitamin D (25-OH) Test

Our easy finger-prick blood test kit offers a convenient way to check your vitamin D level at home, crucial for maintaining strong bones, a healthy immune system, and regulating mood. Symptoms such as fatigue, muscle aches, and frequent colds may indicate a potential deficiency, especially if you spend little time outdoors, have dark skin, or are over 65, factors that can increase susceptibility to low vitamin D levels.

Vitamin D, primarily synthesized in the skin upon sun exposure and converted into its active form, 25 hydroxycholecalciferol (25 OH), plays a vital role in calcium absorption, muscle health, immune function, and mental well-being. Despite its importance, many individuals in the UK have insufficient levels, particularly those with limited sun exposure or darker skin tones. While some vitamin D can be obtained from food sources like oily fish and eggs, addressing deficiency often requires supplementation, as dietary intake alone may not suffice.
