Well.Actually

Are there any side effects of glutathione supplementation

In vascular experiments, nitric oxide related signaling also appears to play a central role, linking BPC-157 activity to endothelial nitric oxide synthase regulation and nitric oxide dependent cellular signaling [7]

NO can react with the cysteine of GSH to form GSNO that may be considered an endogenous NO reservoir, which can release it when it reacts with Cu + or with denitrosylating enzymes such as Trx and GSNO reductase (Sengupta and Holmgren, 2013)

It downregulates p53 and upregulates the expression of SLC7A11 and GPX4, suggesting that it improves cartilage degradation in osteoarthritis by inhibiting ferroptosis through the regulation of the p53 signaling pathway, indicating its potential therapeutic effect in osteoarthritis [166]
