Vitamin B5, also known as pantothenic acid, is a water-soluble vitamin that plays a crucial role in energy metabolism. It helps convert carbohydrates, fats, and proteins into energy, making it essential for overall health. This vitamin is also involved in the synthesis of coenzyme A, which is important for fatty acid metabolism and the production of hormones. Rich sources of vitamin B5 include foods like chicken, beef, potatoes, and whole grains. A deficiency in vitamin B5 is rare but can lead to symptoms such as fatigue, irritability, and digestive issues. Ensuring a balanced diet typically provides sufficient amounts of this important nutrient.
