Under the stimulation of inflammatory factors, indoleamine 2,3-dioxygenase (IDO) catalyzes the conversion of TRP to kynurenine (KYN), thereby initiating this metabolic pathway
In a similar study focused on the hepatotoxic effects of tamoxifen in female rats, it was found that intraperitoneal injection of 45 mg/kg for 10 consecutive days increased the levels of liver enzymes such as ALT, AST, and ALP while decreasing the levels of some cellular oxidative enzymes, such as glutathione peroxidase, glutathione reductase, superoxide dismutase, and catalase 25
This includes people with: Pernicious anaemia (autoimmune destruction of intrinsic factor-producing cells), typically requiring lifelong IM injections Crohn's disease or surgical resection affecting the terminal ileum Coeliac disease causing malabsorption (may improve with gluten-free diet) Chronic pancreatitis reducing enzyme availability needed for B12 release Vegans and strict vegetarians need reliable B12 sources through fortified foods or supplements, as plant-based diets contain negligible amounts of active B12
