People with schizophrenia generally have lower levels of vitamin D. [24] The environmental risk factors of seasonality of birth, latitude, and migration linked to schizophrenia all implicate vitamin D deficiency, as do other health conditions such as maternal obesity. [5] [25] Vitamin D is essential for the normal development of the nervous system.
While some studies have found that vitamin D 3 raises 25(OH)D blood levels faster and remains active in the body longer, [44] [45] others contend that vitamin D 2 sources are equally bioavailable and effective for raising and sustaining 25(OH)D. [46] [47] If digestive disorders compromise absorption, then intramuscular injection of up to ...
To prevent low bone density it is recommended to have sufficient calcium and vitamin D. [17] [18] Sufficient calcium is defined as 1,000 mg per day, increasing to 1,200 mg for women above 50 and men above 70. [18] Sufficient vitamin D is defined as 600 IUs per day for adults 19 to 70, increasing to 800 IUs per day for those over 71. [18]

A broad reference range of 20 to 150 nmol/L (8-60 ng/mL) has also been suggested, [16] while other studies have defined levels below 80 nmol/L (32 ng/mL) as indicative of vitamin D deficiency. [ 17 ] Increasing calcifediol levels up to levels of 80 nmol/L (32 ng/mL) are associated with increasing the fraction of calcium that is absorbed from ...
