Antioxidant Support: NAC is a biologically active precursor for the amino acid cysteine which, in turn, is a precursor for glutathione, a tripeptide with antioxidant properties.* Supports Intracellular Glutathione: Supplementation with N-Acetyl-L-Cysteine is recognized as a safe, highly effective method of increasing healthy intracellular glutathione stores.* Vitamins/Minerals/Amino Acids: Our vitamins/minerals and amino acid formulas are developed to provide beneficial support in filling nutrient gaps.* Key Feature: Antioxidant Support: NAC is a biologically active precursor for the amino acid cysteine which, in turn, is a precursor for glutathione, a tripeptide with antioxidant properties.* Supports Intracellular Glutathione: Supplementation with N-Acetyl-L-Cysteine is recognized as a safe, highly effective method of increasing healthy intracellular glutathione stores.* Vitamins/Minerals/Amino Acids: Our vitamins/minerals and amino acid formulas are developed to provide beneficial support in filling nutrient gaps.* Country of Origin: USA Manufacturer/Importer/Packed By: Douglas Laboratories

The reasons for these discrepancy between the results of our meta-analysis and the other meta-analyses might partly be due to difference between the included subjects, or another possible mechanisms that is not fully understood
Proper handling and storage help minimize degradation processes such as hydrolysis, oxidation, and peptide aggregation, which can affect experimental consistency
