Methylcobalamin is one of the active coenzyme forms of B12 found in the human body
gasseri may act as a ferroptosis inhibitor by producing GSH precursors or stimulating host cell GSH synthesis pathways (e.g., via the Nrf2 signaling pathway [55]), thereby enhancing GSH synthesis or GPX4 activity and protecting epithelial cells from lipid peroxidation
Hormonal Issues : Certain hormonal conditions, particularly those involving the adrenal glands can cause the skin and lips to turn darker
Inhibition of cysteine-glutamate transporter protein system (e.g., Erastin) will deplete intracellular GSH, eventually resulting in the inactivation of GPx4 and the accumulation of lipid peroxidation, which can induce cell ferroptosis to a certain extent [75]
