Vitamin D is the only vitamin that is formed when the sun interacts with the ultraviolet rays of the Sun. Vitamin D is a fat soluble vitamin and it can be found in one of the two forms: vitamin D2 and D3. Vitamin D2 mainly comes from vegetation while D3 is derived through the exposure of the skin to sunlight and by consuming several types of food. Let’s now look at some of the functions of Vitamin D.

Functions of vitamin D are related to skin care problems like persistent skin disease, psoriasis, which is often characterized by patches on ears, scalp and genitalia. The best and the simplest way of getting vitamin D is through having the right contact with sunlight since it contains ultra violet rays that interact with the skin to produce vitamin D. People whose skin is darker and older people have a lower capacity of synthesizing vitamin D when their skin is exposed to Ultra Violet rays from the sun and therefore, such people need an extensive duration of exposure for getting enough concentration of vitamin D in their body. However, it is important to note that excessive exposure can lead to skin cancer along with other skin ailments like skin aging and therefore ten minutes is the maximum one needs for producing vitamin D. The major function of vitamin D in our body is keeping the right levels of phosphorus and calcium. This helps in maintaining and building up strong bones, nails and teeth.

The control of calcium levels in blood and bones is another important function of vitamin D since is helps the mineralization. Another function of vitamin D is also to prevent rickets in kids and osteoporosis in adults. Since vitamin D is a very good antioxidant, it helps in combating prostate cancer, depression, breast cancer, cardiovascular diseases and high blood pressure. It also enhances anti tumor activities within the body. Vitamin D is also great for treating obesity and diabetes, and preventing the onset on sclerosis. Therefore, it can be said that there are multiple functions of vitamin D, which is important for a healthy immune system and extremely important for overall development and growth of the body.

Smatra se da trećina populacije ima nisku razinu vitamina D što može dovesti do niza simptoma od depresije do bolesti srca i raka kože. Ovaj vitamin nije samo potreban za zdravlje koštanog tkiva i zubiju već je odgovoran i za brojne druge funkcije poput usporavanja prijevremenog starenja, uspješne borbe protiv karcinoma te pomaže kod poremećaja ponašanja i depresije. Vitamin D je topiv u mastima i ne razgrađuje se kuhanjem. Vitamin D se prvenstveno sintetizira u koži izloženoj UV svjetlu, ako se ne dobije prehranom ili dodacima prehrani. U organizmu nastaje iz kolesterola. Zato su dostatne količine kolesterola u hrani jedan od preduvjeta stvaranja normalne količine vitamina D. Sposobnost kože da stvara vitamin D se smanjuje s godinama i to za 75% u dobi od 20 do 70, upravo iz tog razloga osobe koje imaju osteoporozu trebaju uzimati vitamin D u obliku dodataka. Uz to, povećava otpornost organizma na infekcije uzrokovane bakterijama. Vitamin D je ključan sastojak za lijep izgled kože Istraživanja pokazuju ako organizam proizvodi dovoljno vitamina D uspješno se mogu smanjiti akne, povećati elastičnost kože, potaknuti proizvodnju kolagena, poboljšati sjaj i smanjiti bore i izgled tamnih mrlja. Jedan od razloga manjka vitamina D je izbjegavanja sunca i svakodnevno nanošenje krema za sunčanje u strahu od preranog starenja i raka. Ako primijetite da Vam je koža blijeda i bez sjaja, imate nisku razinu vitamina D. Iskoristite sunčane dane i dopustite svojoj koži da proizvede dovoljno vitamina D. Vitamin D tijelo proizvodi kad je izloženo sunčevoj svjetlosti, no osobe koje imaju problema s kožom to ne koriste jer se najviše skrivaju upravo od sunca. Osim toga, mnoga zaštitna sredstva za sunčanje blokiraju vitamin D, čak i slabe kreme za sunčanje ( SPF 8 ) blokiraju stvaranje vitamina D za 95%. Mnogi dermatolozi preporučuju uzimanje tableta vitamina D kako bi osigurali dovoljnu razinu vitamina D. Preporuka je oko 400 i.j. na dan. Što se tiče namirnica, možete ga naći u ribi (sardina, tuna) i ribljem ulju, mlijeku, žumancu i prirodnim sokovima.
