This is just an idea to get all studies of nutraceuticals or drugs under one roof so it will make life easier for somebody in the future.
It is good to highlight what looks important also so somebody else doesn't have to wade thru tons of research.
"Although an excess of ROS can wreak havoc on a number of intracellular components, a threshold amount is required to activate the appropriate pathways in phenotypically normal cells [96]. The antioxidant effect of MSM was first noticed when the neutrophil stimulated production of ROS was suppressed in vitro but unaffected in a cell free system [97]; for that reason, it was proposed that the antioxidant mechanism acts on the mitochondria rather than at the chemical level.
Downregulation of COX-2 and iNOS reduces the amount of superoxide radical (O2−) and nitric oxide (NO), respectively [86]. Additionally, MSM suppresses the expression of cytokines such as TNF-α [86,90,91], which may reduce any stimulated mitochondrial generated ROS [98
In vitro studies suggest that MSM does not chemically neutralize ROS in stimulated neutrophils but instead suppresses mitochondrial generation of superoxide, hydrogen peroxide, and hypochlorous acid [97]. Additionally, MSM is able to restore the reduced glutathione (GSH)/oxidized glutathione (GSSG) ratio to normal levels, decrease NO production, and reduce neuronal ROS production following HIV-1 Tat exposure [109]. Animal studies using MSM as the primary treatment for experimentally induced injuries show reductions in malondialdehyde (MDA) [142,143,144,163,164,165], GSSG [165], myeloperoxidase (MPO) [142,143,163], NO [164], and carbon monoxide (CO) [164] and/or increases in GSH [142,143,163,164,165,166], CAT [142,143,144,165], SOD [143,144,163,165], and GPx [165].

Methylsulfonylmethane: Applications and Safety of a Novel Dietary Supplement
Methylsulfonylmethane (MSM) has become a popular dietary supplement used for a variety of purposes, including its most common use as an anti-inflammatory agent. It has been well-investigated in animal models, as well as in human clinical trials and experiments. ...
