Thus, the data from this study support the notion that BH4 can improve oxidative damage and methylation abnormalities in children with ASD with a large effect size, with the caveat that this effect may be more pronounced in those with the more severe abnormalities at baseline
Some peptide exposure beats none

For glutathione, bioavailability is the biggest challenge
Oxidative stress markers: Elevated levels of methylglyoxal (MG) and decreased superoxide dismutase (SOD) activity are associated with DPN, reflecting increased oxidative stress
Pulse amplitude and frequency drive downstream IGF-1 synthesis, drive lipolysis, determine anabolic signaling in muscle and bone
