Vitamin D is an essential nutrient that supports healthy bones, muscles, and immune function. This blood test measures your Vitamin D level to help identify deficiency and ensure your body has enough of this important vitamin for optimal health.
Low Vitamin D is extremely common, particularly in the UK where sunlight exposure is limited during much of the year. Identifying a deficiency early allows you to make informed decisions about diet, supplements, or lifestyle changes before symptoms develop or worsen.
This test can be completed using either a finger-prick home sample or a professionally collected phlebotomy sample.
