Vitamin D – فيتامين (د)

Vitamin D is vital for bones formation and immune system function.

Vitamin D is either supplied in the diet or synthetized in our body in an inactive form that needs the sunlight for its activation.

Vitamin D controls the calcium mineralization in the bone so vitamin D and calcium are quietly linked.

Vitamin D deficiency represents the most common nutritional issue worldwide for both adults and children.

Concerning adults’ vitamin D deficiency is quietly common especially in the gulf countries, that is because of the life style that decreases the sun exposure so much.

Vitamin D deficiency in adults represented by multiple life disturbing problems such as bone and backaches, frequent infection and this becomes more prominent with the high recurrence of the respiratory tract infection, depression, fatigue, hair loss and muscle weakness so it is important to monitor its blood level frequently. Vitamin D deficiency manifestations occur gradually may be over months or years so it is quite difficult to diagnose but the bad consequences of its deficiency made its blood level monitoring very vital.   

Vitamin D insufficiency in children causes rickets a disease in which the bone tissue doesn’t properly mineralize, leading to soft bones and skeletal deformities.
