Many of the best formulations combine kojic acid with complementary ingredients like glutathione, vitamin C, or glycerine
when glutathione falls below approximately 30% of normal, NAPQI covalently binds hepatocyte proteins, causing necrosis
This toxicity is associated with mitochondrial impairments, and is rescued by ferroptosis inhibitors or a mitochondrially targeted ROS scavenger ( Ferroptosis inhibitors have also been investigated in explicit models of neurodegneration
The mechanism involves reduced availability of the precursor amino acids glycine and cysteine in older adults, which directly limits how much glutathione the body can synthesize
Methylation genes tell us genetic predisposition but do not tell us phenotypic expression, which can be modulated by nutrient levels, gut health, toxic load, and use of methylation inhibitors (such as various drugs like PPIs, birth control pills, antibiotics, nitrous oxide, valproic acid, and cholestyramine)
