Β5, also known as pantothenic acid, is a water-soluble vitamin that is part of the B-vitamin complex. It plays a crucial role in the synthesis of coenzyme A, which is essential for fatty acid metabolism and the production of energy from carbohydrates. This vitamin is found in various foods, including meat, eggs, whole grains, and vegetables. A deficiency in Β5 is rare but can lead to symptoms such as fatigue, irritability, and digestive issues. The recommended daily intake varies by age and gender, but it is generally easily obtained through a balanced diet.
