Research Comparison
Glutathione (GSH) vs NAD+ (Nicotinamide Adenine Dinucleotide)
A side-by-side research comparison of Glutathione (GSH) and NAD+ (Nicotinamide Adenine Dinucleotide) drawn from Cobalt 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.
