Vitamin B5 is pantothenic acid, one of the less well known B vitamins, perhaps because it is widely distributed in nature.
Pantothenic acid is virtually ubiquitous. It is present in foods as diverse as poultry, soybeans, yogurt, and sweet potatoes.
No naturally occurring disease due to a deficiency of pantothenic acid has been identified, due to the plentifulness of this vitamin.
An experimental deficiency of pantothenic acid has, however, been created by administering an antagonist to pantothenic acid. This experiment produced disease, thereby demonstrating that pantothenic acid is essential to humans.
Pantothenic acid was discovered in 1940.
- Vitamin B6
A group of closely related chemical compounds with related names — pyridoxine, pyridoxal and pyridoxamine — that are transformed within the body to yet another form of vitamin B6, pyridoxal phosphate, that acts as a coenzyme. (A number of vitamins serve as coenzymes, substances that enhance the action of enzymes and thereby aid in catalyzing […]
- Vitamin C
An essential nutrient found mainly in fruits and vegetables. The body requires vitamin C to form and maintain bones, blood vessels, and skin. Vitamin C is also known as ascorbic acid. Vitamin C is a water-soluble vitamin, one that cannot be stored by the body except in insignificant amounts. It must be replenished daily. Vitamin […]
- Vitamin D
for those 1-70 years of age, 600 IU daily; for those 71 years and older, 800 IU daily; and for pregnant and lactating women, 600 IU daily. The IOM further recommended that serum 25(OH)D levels of 20ng/mL (= 50 nmol/L) is adequate, and levels > 50ng/mL (= 125 nmol/L) could have potential adverse effects As […]

- Vitamin D3
A vitamin produced by the body when exposed to ultraviolet light or obtained from dietary sources. Vitamin D3 is a hormone that has an important role in calcium and phosphorus metabolism. Technically, vitamin D3 is not a vitamin because the body can produce it. Also known as cholecalciferol.
