Pantothenic acid and biotin

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.

  • Eggs

The best way to get the daily requirement of essential vitamins is to eat a balanced diet that contains a variety of foods from the food guide pyramid.
