About this test

Vitamin B2 (Riboflavin) is the least talked-about B vitamin with a very real job: it powers the enzyme systems that convert food into usable energy, helps other B vitamins do their work, and maintains the health of skin, eyes and the lining of the mouth.

B2 deficiency is uncommon on its own — it usually travels with overall poor nutrition, restrictive diets, or gut absorption problems — and shows up as cracked lips with splitting at the corners, a sore or magenta tongue, sore throat, and eye sensitivity to light. Because these overlap with B12 and other deficiencies, testing clarifies which vitamin is actually missing.

The assay is specialised, which is reflected in the price, and is ordered when clinical suspicion is genuine rather than as routine screening. The sample is collected at your home; correction, when confirmed, is straightforward with diet and prescribed supplementation.
