02How They Differ
NAD+
An essential redox coenzyme and sirtuin cofactor central to cellular energy research.
NAD+ (nicotinamide adenine dinucleotide) is a fundamental coenzyme in redox reactions, cycling between NAD+ and NADH to shuttle electrons through central metabolism. It is the rate-limiting cofactor for the sirtuin family (SIRT1–7) of deacetylases studied in cellular-aging research.
Glutathione
The endogenous tripeptide master antioxidant studied for redox and detoxification research.
Glutathione (GSH) is an endogenous tripeptide (γ-glutamyl-cysteinyl-glycine) and the cell's principal thiol antioxidant. Its reactive cysteine thiol neutralizes reactive oxygen species and serves as a substrate for glutathione peroxidase in redox-balance research.

03Selecting for a Research Model
Because NAD+ and Glutathione are both mitochondrial research compounds, they are frequently evaluated against one another. Selection depends on the research question, model system, and endpoints. Both are supplied strictly for laboratory research and are not for human or veterinary use.
Whichever you select, every Ethos Bio lot is verified the same way — a five-point independent panel with a batch-specific Certificate of Analysis. See how we test →
