EMF measurably reduces glutathione in brain tissue and blood across multiple animal studies. The depletion then compounds through a second route: when extracellular glutamate rises, the cystine/glutamate antiporter runs in reverse, cutting cystine import and further reducing GSH synthesis. More glutamate activates more NMDA receptors, which floods more calcium, which generates more oxidative stress, which depletes more GSH
SAH = S-adenosylHcy
If you want systemic effects plus local hair benefit, some protocols combine daily subcutaneous injection with scalp topical
However, these experiments were performed on previously frozen PBMCs, which have been shown not to elicit a type I IFN response following CVB3 infection (115)
Reduced glutathione is the active, stable form that is ready to neutralize free radicals
