Under normal physiological conditions, up to about 9098% of cellular glutathione is in the reduced GSH form, and a shift toward higher GSSG levels is widely used as an indicator of oxidative stress and impaired cellular health
When levels are low, it can lead to fatigue, brain fog, low mood, and general weakness
Other signal transduction systems and metabolic pathways involved in the MGB-based cause of depression include the endocannabinoid system, CAMKII-CREB and MAPK signaling, and glycerophospholipid metabolism
