Vitamin B5


Because pantothenic acid is present in all cells, the man who discovered it in 1933, Dr. Roger Williams, named it after the greek word pantothen, meaning “everywhere.” Pantothenic acid plays a number of essential metabolic roles including the production of some hormones and neurotransmitters. It is also involved in the metabolism of all carbohydrates, fats and proteins.

The best sources of pantothenic acid include eggs, liver, fish, chicken, whole grain breads, cereals and legumes. Other good sources are cauliflower, broccoli, lean beef, white and sweet potatoes, and tomatoes.
