The body cannot produce B12 independently, so it must be obtained through dietary sources or supplementation

98% purity verified by HPLC

To limit potentially life-threatening depletion of intracellular antioxidant/GSH stores, epithelial cells have developed numerous compensatory pathways, including the cystine-glutamate antiporter (SLC7A11), which critically maintains de novo GSH biosynthesis by increasing intracellular cystine levels (9)

Hence, large sample size is possibly needed to achieve discrete conclusions
