Zależności między poziomem witaminy D a ilością tkanki tłuszczowej człowieka

Vitamin D3, apart from maintaining calcium and phosphate homeostasis, also has a significant influence, among others, on: the immune system, the muscular system or the circulatory system. Due to the presence of vitamin D receptors in many cells of the body, its multidirectional action is observed. Improper diet and lack of exposure to sunlight can lead to vitamin D deficiencies and promote the development of e.g. osteoporosis and rickets in children. Recent studies have shown that changes in vitamin D levels can affect the formation of metabolic diseases such as type I diabetes and lead to the development of overweight and obesity. In people with lowered levels of vitamin D occurrence of increased body weight is observed, which may be related to the hypothesis of the so-called postponing vitamin D in excessive amount of adipose tissue. On the other hand, there are reports that vitamin D reduces the amount of adipose tissue. More studies should be conducted to verify the molecular basis of the correlation of the influence of vitamin D concentration on the phenomenon of overweight and obesity.
