Pantothenic acid, also known as vitamin B5, is a water-soluble vitamin that plays a crucial role in the body's metabolism. It helps convert carbohydrates, fats, and proteins into energy, making it essential for overall health. This vitamin is found in a variety of foods, including meat, eggs, whole grains, and vegetables. Additionally, pantothenic acid is important for the synthesis of coenzyme A, which is vital for fatty acid metabolism and the production of hormones. A deficiency in this vitamin is rare but can lead to symptoms such as fatigue, irritability, and digestive issues.
