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.

FAQs
The best way to get essential vitamins and minerals is from food. However, if your body cannot absorb certain nutrients properly, or you are not able to get enough of them through your diet, then you may consider taking a supplement for that nutrient. B vitamins are water-soluble. A water-soluble vitamin dissolves in water and is easily absorbed by the body. Your body does not store these vitamins for long, so any extra will be eliminated in your urine. Because of this, it is important to consume them every day.
While it is unlikely to get too much of a micronutrient if you are taking a supplement, getting too much, known as vitamin toxicity, is possible. It is recommended to confirm a deficiency through testing and talk with your doctor prior to taking supplements.
An enzyme is a protein that helps to start, or speed up, a reaction in the body. A coenzyme is a non-protein molecule that helps an enzyme to perform that reaction.
