About the Test

The Vitamin B Supplement Panel measures the levels of the following 3 vitamins and minerals in your blood: vitamin B2, vitamin B3, and vitamin B5.

Identifying and addressing nutritional deficiencies are important steps toward better health. Your body does not produce most vitamins and minerals, so you must get them through food or supplements. How nutrients work in your body is influenced by more than just what you eat. These factors include genetics, age, health conditions, medications, metabolism, and how well your body absorbs nutrients.


How it works offers 100+ consumer-initiated Quest Diagnostics lab tests to empower you to have more control over your health journey. Choose from a variety of test types that best suit your needs.
