Also known as vitamin PP, this vitamin is truly precious for our health. It promotes metabolic activity and in particular is able to facilitate the absorption of carbohydrates, fats and proteins in our body. It has a protective role on our skin (which keeps it toned and young). It promotes cell oxygenation and therefore has the ability to prevent cellular degeneration of various kinds. It helps to promote normal blood circulation and is therefore very useful for our cardiovascular system. It has protective properties on our nervous system (a bit like all B vitamins) which helps it function regularly. It promotes bile secretion and is therefore particularly beneficial for our liver. For all these reasons this vitamin is essential for maintaining a good state of health in our body. It is found in meat and fish, whole grains, spinach, eggs, dried fruit, etc. Its deficiency can cause alterations of the nervous system and neuropsychiatric disorders of various kinds, states of exhaustion, loss of memory as well as problems with the digestive system and our skin (with rashes of various types). An excess of it can instead cause hypotension, headaches and a sense of anxiety and general malaise. states of exhaustion, memory loss as well as problems with the digestive system and our skin (with rashes of various types).
