Finally, other antioxidant vitamins, like vitamin C and E, and anti-inflammatory phytonutrients, as curcumin and polyphenols, may support muscle recovery and mitigate exercise- and diet-induced oxidative stress, although further studies are needed to determine their direct impact on lean body mass during energy restriction [59,60,61]
Moreover, IHC analysis of filaggrin and loricrin, key proteins involved in epidermal barrier function, revealed that glutathione amino acid precursors treatment enhanced their levels in UVB-exposed skin, supporting the protective effects of glutathione amino acid precursors on barrier function
And over time, if you smoke cigarettes, drink alcohol and eat processed foods, those things cause oxidative stress
GH was also found to promote an increase in mitochondrial oxidative capacity and abundance of several mitochondrial genes when acutely administered (209) while exogenous administration of IGF-1 was associated with a reduced susceptibility of dystrophic muscles to contraction-induced injury (210)
