Common causes include: Pernicious anemia, an autoimmune disorder hindering Vitamin B12 absorption Gastrointestinal surgeries, like gastrectomy, impact Vitamin B12 uptake Long-term use of certain medications, such as metformin or proton pump inhibitors Diets lacking in Vitamin B12, often seen in vegans and vegetarians For those without a deficiency, Vitamin B12 injections are not typically recommended, as their body can naturally regulate and excrete excess amounts of the vitamin
Lowering GSH levels also triggers ferroptosis through deactivation of GPX4, leading to accumulation of lipid peroxides [87] In some cases, GSH depletion alone can induce therapeutic effects without relying on Fenton chemistry, which typically involves HO reacting with Fe 2 to form hydroxyl radicals (OH) that damage critical biomolecules such as DNA, proteins, and lipids

The depletion of glutathione also plays a critical role in the exacerbation of mast cell activation syndrome (MCAS) and dysautonomia, including postural orthostatic tachycardia syndrome (POTS)
