No, primarily because the enzymes could adversely impact proper absorption

It can be obtained by diet, the endogenous reserve known as glycogen or synthesized via gluconeogenesis (125)

The accumulating GSSG is rapidly reduced to GSH by the NADPH-dependent glutathione reductase [26, 27] or, if GSSG reduction is limited, can be exported from cultured astrocytes to slow-down the rapid oxidation of the cellular thiol reduction potential [24, 25]

Our findings demonstrate that GPR68 downregulation exacerbates ferroptosis damage by disrupting the PI3K/Akt/Nrf2 antioxidant axis, while pharmacological activation of GPR68via the benzodiazepine Lorazepamrescues neuronal viability through this pathway
