DIFFERENT ASPECTS OF VITAMIN D

Öz

Summary Vitamin D is a steroid hormone synthesized by sunlight and this happens in the skin. It undergoes various metabolic changes in different tissues in the body and turns into its active form. Although it shows its main effect on bone tissue due to calcium phosphorus metabolism, it has also been proven to have extra-bone effects. Starting from intrauterine life until the end of life; It is effective on growth-development, immune system, neuronal development. In this review prepared in the light of up-to-date information; It is aimed to underline the importance of using vitamin D especially from childhood by reviewing the positive and negative reactions of vitamin D with different systems. Özet D vitamini güneş ışığı ile sentezlenen steroid yapıda bir hormondur. Vücutta farklı dokularda çeşitli metabolik değişikliklere uğrayarak aktif formuna dönüşür. Temel etkisini kalsiyum fosfor metabolizması dolayısı ile kemik doku üzerinde göstermekle beraber kemik dışı etkileri olduğu da kanıtlanmıştır. İntrauterin yaşamdan başlayarak hayatın sonuna kadar; büyüme gelişme, immün sistem, nöronal gelişim üzerine etkilidir. Güncel bilgiler ışığında hazırlanan bu derlemede; D vitamininin farklı sistemler üzerindeki etkilerinin gözden geçirilerek özellikle çocukluk çağından itibaren D vitamin kullanımının önemini vurgulamak amaçlanmıştır.
