Vitamina D, comparativo de absorção à exposição solar versus suplementação: uma revisão.

Abstract

Vitamin D is a molecule universally present in living beings and, although called vitamin is actually a steroid hormone. It can be synthesized in the skin from exposure to sunlight or from dietary sources as well as supplements. Recent evidence correlate insu fi aware vitamin D levels with an increased risk of developing other non-bone pathologies such as: cardiovascular diseases, hypertension, cancer, diabetes, multiple sclerosis, dementia, rheumatoid arthritis, infectious disease. This work seeks to describe on the comparison between the absorption of vitamin D by the body through exposure to sunlight compared to supplementation by multivitamins. A literature review was conducted in Medline, Pubmed, Lilacs, Scielo and national and international health committees of the articles published in the last 10 years, covering about vitamin D. The following search terms (keywords and delimiters) were used in various combinations: 1) Vitamin D; 2) multivitamins; 3) Solar Orientation; 4) prevention and treatment. They found 116 articles, and these were used 76 articles and two doctoral theses. It was concluded that insufficient levels of vitamin D are associated with low frequency of exposure to the sun, and quantities ingested in the diet and the benefits achieved with supplementation are lost after stopping its use regular exposure to the sun is the main way of getting vitamin D in comparison to other forms.
