Nutrient Deficiencies (Building Blocks Missing) Glutathione synthesis requires specific nutrients: Cysteine : From dietary protein (whey, eggs, poultry)-rate-limiting Glycine : Often deficient in modern diets (need 10-15g/day, most get 3-5g) Selenium : Cofactor for glutathione peroxidase (GPx) , the enzyme that recycles GSSG back to GSH B vitamins (B6, B9, B12): Required for methylation and sulfur metabolism Vitamin C : Recycles oxidized glutathione Deficiency in any of these impairs glutathione production or recycling [5]
