About the test

Vitamin B2, also known as Riboflavin, plays a crucial role in the metabolism of fats, carbohydrates, and proteins. A deficiency in Vitamin B2 can lead to a variety of non-specific symptoms, making it hard to diagnose without a test. These symptoms can include issues with the mouth and skin, such as sores, corneal vascularization (affecting the eyes), anemia, and even personality changes.

Who might consider it:

This test is essential for individuals showing symptoms of Vitamin B2 deficiency or those at risk due to poor dietary habits.
