NAD+

NAD+ (nicotinamide adenine dinucleotide) is the coenzyme every cell uses to move electrons through energy metabolism, and the fuel that sirtuins, PARPs and CD38 consume. The big shift in recent research is about where it sits inside the cell. In 2020, Nature identified SLC25A51 as the transporter that carries intact NAD+ into mammalian mitochondria, and it opened a new line of work on the mitochondrial NAD+ pool. That's why labs buy the NAD peptide, as people often search for it, to study the molecule directly.

Here's how NAD+ fails. The powder is hygroscopic, and moisture, heat or the wrong pH hydrolyzes it into nicotinamide and ADP-ribose, while a partly degraded vial can still look like clean white powder. Solutions decompose rapidly in acid or alkali. Mix-ups happen too: reduced NADH differs by just two hydrogens, so a label alone can't be trusted. Titan Core labels this compound for what it is, a coenzyme with no amino-acid sequence. It's made in the USA, measured by HPLC at an independent lab, which separates intact NAD+ from its breakdown products, and packed to keep moisture out. The report carries the same LOT as your vial. It's sold for laboratory research, not as a supplement, and isn't for human or animal use.
