Vitamin B5 is very important for the correct assimilation of fats, carbohydrates and proteins in our body. It is therefore directly involved in the so-called “energy metabolism” or in those processes in which the organism converts the active ingredients of food into real energy. It has the ability to protect our skin and our hair system from many forms of degeneration. It promotes the healing of the skin in case of wounds of all kinds. It promotes the correct functioning of our nervous system and seems to have a preventive role in many pathologies of the same. It has the ability to strengthen our immune system. It is widely available on our tables since it is found in so many. In particular, it is abundant in whole grains, legumes, dried fruit, in egg yolk, milk and its derivatives. Its deficiency can cause neurological disorders, a lowering of the sensation of energy in our body, irritability and muscle cramps. An excess of it (very rare in the absence of specific pathologies) does not seem to cause particular problems for the human body.
