Vitamin B7 is very important for our health. In particular for the health of our brain. In particular, it has antidepressant properties, helping brain activity to be more active and safer. It is therefore very useful for elderly people who complain of depressive states and cognitive deficits. It also helps the brain maintain a good memory and for this reason it is particularly suitable for older individuals. It has the ability to prevent the accumulation of fats in the liver and therefore promotes good functionality of this organ. It also has the ability to preserve the health of our nervous system by preventing neurological degeneration of various kinds. It has the ability to stimulate lecithin in our body. This substance is very important for keeping the internal walls of veins and arteries “clean” and is therefore very useful for the cardiovascular system as a whole. It is contained in citrus fruits, whole grains, brewer’s yeast, nuts, bananas and also in meat and fish. A deficiency of this vitamin (quite rare in the absence of diseases) can cause states of acidosis, skin and neurological problems. An excess of it (also quite rare in the absence of specific diseases) can cause nausea and gastrointestinal problems.
