- Abstract
Vitamin D is not a vitamin in the proper sense of the word, for two reasons. First of all, our body can produce it after the sun exposure. Secondly, in its active form, it is considered a hormone. Specifically, it has effects as a hormone in mineral absorption, bone mineralization and some secretions. Due to the role of vitamin D in the minerals absorption and in the process of bone mineralization, it is extremely important in maintaining bone density. Studies show that supplements with calcium and vitamin D can prevent bone problems and improve bone density in the elderly. These two types of supplements together have shown a reduction in the hip fracture rate - a particularly good thing which hormone replacement therapy has not proven to achieve. There is real evidence that vitamin D can be a reliable help in preventing and treating many cancers, such as colon, breast or prostate cancer. But high levels of vitamin D may increase the risk of pancreatic cancer if one does not have a balanced diet, does not maintain normal weight and fall prey to sedentarism. The richest natural sources are salmon, mackerel, tuna, sardines, egg yolk, beef liver, cereals, nuts, apples, dairy etc. If these are not enough, you can also use vitamin D dietary supplements that are found in two forms: D2 - ergocalciferol (the same type found in food) or D3 cholecalciferol (the form obtained from sun exposure).
