About Vitamin B5 (Pantothenic Acid)

B vitamins are nutrients that your body needs to work well and stay healthy. There are eight different types. A vitamin B test checks the level of one or more B vitamins in a sample of your blood or urine (pee).

All the B vitamins together are called the "B vitamin complex." Each type of vitamin B plays different important roles in your body.

Vitamin B5, also called pantothenic acid, is part of two molecules (coenzyme A and phosphopantetheine) that help your body break down and use fats. It's needed by nearly all living things and is found in a wide variety of foods.

You get B vitamins from many foods, including leafy green vegetables, meats and fish, eggs, whole grains, milk, and other dairy products. A lack of vitamin B is rare in the United States, because many foods have added B vitamins. These foods include cereals, breads, and pasta.

Interpretation

Your results will show the amount of vitamin B5 (pantothenic acid) that was tested. If your level is normal but you still have symptoms, you may need other tests to find the cause.

If you're lacking in vitamin B5, your provider will look for the reason. You may need other tests to confirm the diagnosis. Treatment may include taking vitamin B supplements; in certain cases, vitamins may be given by intravenous (IV) treatment.

If you have questions about your results, talk with your provider.
