Glutathione (GSH) vs NAD+ (Nicotinamide Adenine Dinucleotide)
A side-by-side research comparison of Glutathione (GSH) and NAD+ (Nicotinamide Adenine Dinucleotide) drawn from Cedar Peptides' peptide database records.
Glutathione (GSH)
Glutathione (GSH) is a naturally occurring tripeptide composed of glutamate, cysteine, and glycine, often referred to as the body’s primary intracellular antioxidant. It is present in virtually all cells and plays a central role in maintaining redox balance, detoxification, and immune function. Levels of glutathione decline with age and are depleted by oxidative stress, toxins, and disease states. Injectable administration bypasses poor oral bioavailability, enabling rapid elevation of plasma glutathione levels and supporting systemic antioxidant defense and detoxification pathways.
NAD+ (Nicotinamide Adenine Dinucleotide)
Nicotinamide Adenine Dinucleotide (NAD+) is an essential coenzyme present in all living cells, playing a central role in energy production, DNA repair, and cellular metabolism. It functions as a key redox carrier, cycling between oxidized (NAD+) and reduced (NADH) states to drive mitochondrial ATP production. NAD+ levels decline significantly with age (up to ~10–50% across tissues), contributing to reduced mitochondrial efficiency, increased oxidative stress, and impaired cellular repair. Injectable NAD+ bypasses oral absorption limitations, providing immediate systemic availability and rapid cellular uptake.
Reading a comparison
A comparison places two records side by side; it does not merge them. Each description above is drawn from that compound's own record, and the two were not necessarily characterised by the same methods, at the same time, or to the same level of detail. Before comparing any attribute, it is worth establishing that both records describe the substance you think they describe — names are not identifiers, and two entries sharing a name can differ in salt form, stereochemistry or the convention used to state a mass. Where a figure carries no method beside it, the comparison is between two reported numbers rather than between two measurements.
