Vitamin B5 (Pantothenic Acid)
Pantothenic acid is a water-soluble vitamin that plays a central role in cellular metabolism. There is a close relationship between pantothenic acid levels in tissues and the normal functioning of the adrenal cortex. Pantothenic acid supports adrenal activity and is involved in the production of cortisone and other adrenal hormones, which are important for the body’s response to stress.
Vitamin B5 is an essential component of coenzyme A (CoA), a key molecule required for energy production. As a coenzyme, pantothenic acid is involved in the release of energy from carbohydrates, fats, and proteins. Because coenzyme A participates in so many metabolic reactions, pantothenic acid is critical for overall energy metabolism.
Pantothenic acid is also required for the synthesis of cholesterol, steroid hormones, and fatty acids. Through these roles, it supports hormone production, cell membrane integrity, and normal metabolic balance. It also assists in the utilization of other vitamins, particularly riboflavin, highlighting the interdependence of the B-complex vitamins.
Pantothenic acid has historically been described as helping the body adapt to stressful conditions, largely because of its relationship to adrenal hormone production and energy metabolism.
Deficiency of pantothenic acid is uncommon, as it is widely distributed in foods. When deficiency does occur, reported symptoms may include restlessness, fatigue, abdominal pain, nausea or vomiting, muscle cramps, gas and abdominal distention, and a burning sensation in the feet.
