One of the reasons DMSO has been studied for decades is its role as a direct free radical scavenger. Unlike many antioxidants that work indirectly through signaling pathways, DMSO can chemically neutralize hydroxyl radicals — some of the most damaging free radicals in biology — by quenching their unpaired electron and stopping oxidative chain reactions. This is basic chemistry and cell biology, not hype. Understanding how something works always matters. #DMSO #FreeRadicals #OxidativeStress #Cell
