A recent data science evidence-based approach to determine the top ten ingredients in oral skin supplements (from 71,000 dietary ingredients of which 1781 were found to have at least one skin-related publication assessed in human clinical trials) found that collagen had the most published human skin health-related data, followed by specific antioxidants (especially from natural sources or products) [25]
Multiple studies have shown that supplementing with whey protein can increase glutathione production, helping to reduce oxidative stress in the body[12]
For research-grade DSIP material, identity and purity verification (RP-HPLC area percent, mass-spectrometric confirmation of the WAGGDASGE sequence, residual-solvent and water content) is non-optional given the literatures documented sensitivity to analogue substitutions and degradation products
Supplement timing, dosage, and safety decisions should be made in consultation with your prescribing physician, especially if you have pre-existing liver conditions or are taking medications that affect hepatic detoxification pathways
Further, targeted metabolomics and isotope tracing experiments uncovered GGCT as a metabolic orchestrator to prioritize Gln to GSH flux for antioxidant defense, while activating glucose (Glc)-fueled anaplerosis to replenish TCA intermediates to fuel proliferation
