Pantothenic acid and biotin
Information, Symptoms, Treatments and Resources
Pantothenic acid and biotin are types of B vitamins. They are water-soluble, which means that the body can't store them. If the body can't use all of the vitamin, the extra leaves the body through the urine. Therefore, these vitamins must be replaced every day.
Pantothenic acid and biotin are essential to growth. They help the body break down and use food. This is called metabolism.
Pathothenic acid is also called vitamin B5. It helps break down carbohydrates, proteins, and fats. Biotin also helps break down proteins and carbohydrates.
Pantothenic acid and biotin are found in foods that are good sources of B vitamins, including the following:
- Eggs
- Fish
- Milk and milk products
- Whole-grain cereals
- Legumes
- Yeast
- Broccoli and other vegetables in the cabbage family
- White and sweet potatoes
- Lean beef
There are no known deficiencies of either pantothenic acid or biotin. Large doses of pantothenic acid do not produce symptoms other than (possibly) diarrhea. There are no known toxic symptoms associated with biotin.
