Vitamin B9, like all B vitamins, is precious for our metabolism and in particular for energy metabolism (it has the ability to transform carbohydrates into glucose). It has healthy properties for our nervous system which helps keep us healthy. It has a protective action on our skin and on the hair system as a whole (it is also very beneficial for our hair). It guarantees the correct functionality of the genital organs and fertility at every stage of life. It is fundamental for the natural development of the various organs of the human body (it is particularly important during pregnancy for its role in the formation of the organs of the unborn child). This vitamin is therefore very important for the set of benefits that it is able to bring to the functionality of our organism as a whole. It is found in green leafy vegetables, legumes, fruit (both fresh and dried), whole grains, etc. A deficiency of vitamin B9 can be very serious during pregnancy because it can affect the formation of the unborn child’s organs ( can therefore favor congenital malformations). In adults it can lead to diseases of the nervous system, skin and cardiovascular system. An excess of vitamin B9, on the contrary, does not seem to expose our body to particular contraindications.
