Vitamin D Blood Test

Anyone living in the UK — where sun exposure is insufficient for optimal vitamin D synthesis for at least six months of the year. Particularly important for people with darker skin tones, those who work indoors, or anyone supplementing who wants to confirm their dose is working.

Your vitamin D level measured against clinical reference ranges — deficient, insufficient, sufficient, and optimal — telling you clearly whether to supplement, adjust your current dose, or maintain your approach.

Vitamin D deficiency is the most prevalent nutrient deficiency in the UK. Its effects span immunity, bone density, mood, and hormonal health — but it is entirely correctable once identified. Supplementing without testing means guessing a dose that could be too low to help or, at high doses, high enough to cause harm.
