Two redox molecules, not two versions of the same one
NAD+ 1,000 mg is studied as a cellular redox cofactor in energy-metabolism research and in sirtuin- and PARP-associated enzyme systems. Glutathione 1,500 mg is studied as a redox cofactor in oxidative-stress assays and glutathione-dependent enzyme systems. Labs measure them with different methods because they are different molecules.
A glutathione result does not stand in for an NAD+ measurement, and an NAD+ measurement does not stand in for glutathione.
The NAD+ report has no purity percent
NAD+ task 157318, batch Nad-1000, analysis May 15, 2026, prints 929.05 mg. It does not print a purity percent. Leave that field blank. Do not borrow a purity number from another product.
Glutathione task 165760, analysis May 20, 2026, prints 1529.69 mg and purity 99.052%. The catalog label is 1,500 mg. The measured mass and the label are both on the record, and they are not the same sentence.
