Vitamin C: Vitamin C and glutathione work in a continuous loop
How to implement: Dosing: 20-40 grams daily (post-workout or as snack) Choose undenatured whey (cold-processed, preserves bioactive peptides) Whey protein isolate (higher protein content, lower lactose) Best sources: Grass-fed whey isolate : Highest cysteine content Undenatured whey concentrate : Preserves immunoglobulins and glutathione precursors Avoid heat-treated : Heat denatures cysteine Timing: Post-workout (supports muscle recovery + glutathione synthesis) Morning (with breakfast) For vegans: Pea protein isolate : Lower in cysteine but can be paired with NAC Hemp protein : Moderate cysteine content Evidence: A randomized trial found that 20 grams of whey protein daily for 3 months increased lymphocyte glutathione by 35% and improved immune markers in HIV patients [15]
But for longer-lasting results multiple sessions are usually recommended by our experts
Proximal insulin receptor signaling and IR Insulin exerts its biological effects by binding to its cell-surface receptors, therby activating specific adapter proteins, such us the insulin receptor substrate (IRS) proteins (principally IRS1 and IRS2), Src-homology 2 (SH2) and protein-tyrosine phosphatase 1B (PTP1B), eventually promoting downstream insulin signaling involving glucose homeostasis
Glutathione supports both Phase I and Phase II liver detoxification, with GSH conjugation constituting a major elimination pathway for drugs, metabolic waste products, and environmental toxins
