glutathione oral bioavailability percentage delivery of glutathione: antioxidant function, barriers and strategies – ScienceOpen standard oral glutathione bioavailability percentage

Different reconstitution volumes produce different concentrations from the same vial: 50mg vial + 2ml water = 25mg/ml (very concentrated) 50mg vial + 2.5ml water = 20mg/ml (concentrated) 50mg vial + 5ml water = 10mg/ml (standard) 50mg vial + 10ml water = 5mg/ml (dilute) Higher concentrations require smaller injection volumes but may exceed solubility limits for some peptides
