vitamin D deficiency

Very many people in the world suffer from vitamin D deficiency or insufficiency: it would be necessary to run for cover, before the problem becomes pathological. According to researchers, about one billion people worldwide suffer from vitamin D deficiency or insufficiency. The most affected populations are those who live far from the equator, especially those living in the Mediterranean and, in the same way, individuals affected by certain pathologies such as obesity, liver and kidney diseases, celiac disease, or even elderly and people with dark skin; the latter due to the high levels of melanin present in their organism, which prevent the absorption of the vitamin through the sun's rays.

The lack of vitamin D can cause several more or less serious illnesses, from the most small to older. In fact, every tissue in the human body has receptors for this vitamin, which are contained in the brain, heart, muscles and the immune system. This means that it is vital for the functioning of the human body at all levels. In addition to being a vitamin, it is also a hormone that helps the absorption of calcium, helping to build bones, teeth and muscles. But not only that, as mentioned, because its function is also to activate the genes that regulate the immune system and release neurotransmitters, such as dopamine and serotonin, which help brain functioning and development.

Researchers have identified vitamin D receptors on different cells located in the brain, in the same regions linked to depression. Easy conclusion, the connection between vitamin D and mood or depressive states is now proven by several studies. According to experts, the ideal level of vitamin D in the blood should be between 50 and 75 ng / mL, so supplements could lead back to normal levels, while improving mood.

It must be said that the research is still in its early stages, but investigations confirm the role of this precious substance in the pathophysiology of depression and as a potential cure for this disease.

Unfortunately, the effects of vitamin D deficiency inherent in mental health can also be of great importance, such as schizophrenia, or cause more "usual" conditions but nevertheless annoying as sudden changes in mood. It is therefore necessary to find the right path, pharmacological or life-style, to overcome this deficiency.
