Cysteine is frequently identified as rate-limiting, or limiting the ability of glutathione synthesis based on lack of availability
Neurology (Parkinsons disease) Intranasal GSH: A phase I, single-group pilot in Parkinsons disease demonstrated acute CNS uptake by MRS after intranasal administration, establishing feasibility but not clinical efficacy

These were further filtered using terms related to fatty liver disease: fatty liver, non-alcoholic fatty liver disease, NAFLD, fatty liver hepatitis, metabolic associated fatty liver disease, MAFLD, metabolic dysfunction-associated steatotic liver disease, and MASLD. This work provides theoretical support and a reference for research on TCM approaches to the prevention and treatment of liver diseases, and important scientific evidence for developing safe, effective drugs for treating fatty liver

Reductions in glutathione synthesis and tissue glutathione concentrations in aged animals (compared to younger ones) are suggestive of a potentially lower ability to respond to oxidative stress or toxin exposure (28)
