Vitamin B5, better known today as pantothenic acid, is a vitamin from the B complex. The name of this vitamin derives from the Greek word "pantothen", meaning "from everywhere". Vitamin B5 is found in almost all animal and plant foods, and it is used almost everywhere in the body. As a key component of Coenzyme-A, it is involved in all metabolic processes in the body, including building and breaking down protein, fats and carbohydrates and converting these macronutrients into energy. In addition, it has a stimulating effect on metabolism and digestion, which can aid during a diet. Furthermore, vitamin B5 is involved in the development of other vitamins and accelerates antibody formation and wound healing in cases of illness. Furthermore, vitamin B5 is often referred to as "skin and hair vitamin", on the one hand it can counteract premature wrinkling or a premature graying of the hair. On the other hand, it protects the skin from strong X-rays. The daily requirement for vitamin B5 is between 6 and 10 mg. In stressful situations, infections or injuries, the need is greatly increased. Since the vitamin is present in almost all foods, it is not very difficult to meet the daily needs. Particularly rich sources are offal, especially the liver and heart of calves, but also beef, trout or salmon are ideal as vitamin B5 suppliers. Vegetarians should increasingly resort to dairy products, mushrooms, potatoes or nuts. Since vitamin B5 is one of the water-soluble vitamins, cooking should be avoided. Since the vitamin is sensitive to light and heat, the food should be stored in a cool and dark place. Deficiencies are very rare in connection with vitamin B5, which is due to the diverse availability of the vitamin. As long as you eat a balanced diet you do not have to fear a shortage. A possible lack of vitamin B5 may manifest as depression, high stress sensitivity, fatigue, or decreased brain function.
