Vitamin D is one of the most important vitamins for humankind and %95 of its requirements are acquired by synthesising solar rays on skin. While lack of vitamin D can lead to many diseases, especially cancer, the ones who get vitamin D in an appropriate level, can reduce this risk if they exercise. If, also, vitamin D level is high, obesity risk will be minimized because of eating less thanks to leptin hormone. Vitamin D receptors exist in approximately 40 tissues. The most imporant effect of vitamin D, which dissolves in fat, is on bone mineralization phosphorus metobolism and calcium. People whose vitamin D level is low, should take nourishment by sources rich in vitamin D instead of helper pills.

Vitamin D ve Metabolik Fonksiyonları

Öz

Vitamin D,insanoğlu için en önemli vitaminlerden biridir ve ihtiyacının %95’i güneş ışınlarının cilde sentezlenmesiyle karşılanır.Vitamin D eksikliği özellikle kanser gibi bir çok hastalığa yol açabileceği için,yeterli bir seviyede vitamin D alanlar eğer egzersiz yaparlarsa bu riski azaltabilirler.Aynı zamanda vitamin D seviyesi yüksek olursa,leptin hormonu sayesinde daha az yemek yeneceği için obezite riski minimuma inecektir.Vitamin D reseptörleri yaklaşık olarak 40 dokuda vardır.Yağda çözünen vitamin D’nin en önemli etkisi kemik minerilizasyonu fosfor metabolizması ve kalsiyum üzerinedir.Vitamin D seviyesi düşük olan kişiler,yardımcı ilaçlar yerine vitamin D açısından zengin olan kaynakların besinlerinden sendromlar,bulaşıcı,otoimmün ve kardiyovasküler gibi bir çok hastalıkla ilişkisi olduğu bildirilmiştir.Gözlemsel çalışmalarda,endüstrileşmiş ülkeler de dahil olmak üzere dünyanın kuzey bölgelerinde vitamin D eksikliğinin çok yaygın olduğu anlaşılmıştır
