Vitamin B5

Vitamin B5, also known as pantothenic acid, helps the body convert food into energy. Like all B vitamins, this one is important for regulating the nervous system. Vitamin B5 also plays a big part in manufacturing red blood cells and hormones produced by the adrenal glands. It is also important for the health and strength of skin, hair and eyes.
There is mounting evidence today that suggests taking vitamin B5 may reduce triglycerides in people who are dealing with high cholesterol. Vitamin B5 was first identified by scientists in the United States in 1933.

Signs of a Vitamin B5 Deficiency

Dietary issues cause deficiencies in B5. A vitamin B5 deficiency can manifest through fatigue, irritability or a burning sensation in the feet. Other people experience more serious symptoms that may include stomach pains, vomiting and upper respiratory infections.

Vitamin B5 Excess

Like other water-soluble vitamins, vitamin B5 poses a very small risk for overdoses. However, mixing this vitamin with certain medications can create complications that should be discussed with your physician. Side effects of taking too much vitamin B5 are typically gastrointestinal.
Some people may experience diarrhea, nausea and heartburn when large doses are taken.



The amount of vitamin B5 a person should take depends on age.

  • Infants under six months of age should have 1.7 milligrams daily.
