OFC is also called von Recklinghausen disease of bone. The major mechanism for intestinal iron reduction involves a ferrireductase that is a member of the cytochrome b561 class of transmembrane redox enzymes. The retinaldehyde forms of vitamin A are also commonly referred to as retinals. Some cheeses are also fermented in a way that optimizes their vitamin K content.
Both vitamin D 2 and D 3 enter the bloodstream and are taken up by the liver.
The truth is that every medication, including over-the-counter drugs, depletes your body of specific, vital nutrients. Iron homeostasis is critical for cell survival.

Pak CY. The PANK4 gene is located on chromosome 1p36. However, long term antibiotic treatment can lead to deficiency in adults. Apr1999;55 2: Pernicious anemia is a megaloblastic anemia resulting from vitamin B 12 deficiency that develops as a result of a lack of intrinsic factor being released from stomach parietal cells leading to subsequent malabsorption of the vitamin.
