Copper toxicity considerations Copper toxicity from GHK-Cu is extremely unlikely at standard doses but remains a theoretical concern worth understanding
In 2011, for example, researchers who administered 1,000mg per day of non-liposomal glutathione found "no significant changes were observed in biomarkers of oxidative stress" in participants after four weeks.2 In contrast, a 2019 study of identical length administered liposomal glutathione at 500-1,000mg doses and saw significant decreases in oxidative stress biomarkers plus improvements in immune system markers.3 Two of our top recommended glutathione supplements are liposomal, by the way: Codeage Liposomal Glutathione, our recommendation for most people Quicksilver Scientific Glutathione, our top liquid glutathione supplement Branded glutathione Glutathione supplements often use one of two branded versions of glutathione that are formulated to improve absorption: Setria or Opitac
