Getting regular exercise boosts natural glutathione production

Certain genetic variants in glutathione synthesis enzymes (GCLC, GCLM, GSS) and metabolism pathways influence how efficiently your body produces and recycles glutathione

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]
