Vitamin B2 (Riboflavin)

The Vitamin B2 (Riboflavin) Blood Test measures levels of riboflavin, a vitamin that helps your body turn food into energy and supports healthy red blood cells. Low B2 can cause fatigue, mouth sores, cracked lips, and increase the risk of anaemia, while good levels help maintain energy and overall health.

Vitamin B2 (Riboflavin)

Experiencing skin issues, eye sensitivity, or fatigue and want assessment of energy metabolism and riboflavin status for optimal cellular health?

Overview

The Vitamin B2 test measures riboflavin levels in your body—think of this vitamin as your cellular energy manager that helps convert the food you eat into usable fuel while also acting as a protective shield against harmful cellular damage. Riboflavin works behind the scenes to keep your skin glowing, your eyes healthy, and your nervous system running smoothly, making it essential for feeling energized and maintaining overall vitality.

This test becomes particularly valuable when you're experiencing unexplained fatigue, skin issues around your mouth or nose, eye sensitivity, or slow wound healing—all potential signs that your body's riboflavin levels might be running low. Whether you follow dietary restrictions, have digestive issues that affect nutrient absorption, or simply want to understand why you're feeling run down, measuring your B2 levels can help pinpoint whether this crucial vitamin is the missing piece in your health puzzle and guide you toward the right nutritional support.
