You have to have NAD precursors”—that is, five predominant chemicals that combine to make up the NAD+ molecule, including NR (nicotinamide riboside) and NMN (nicotinamide mononucleotide).

The first time I heard mention of NAD (pronounced “nad” not “N-A-D” by its evangelists) it was from the mouth of Joe Rogan.

NMN, an abbreviation for nicotinamide mononucleotide, is a crucial molecule involved in the production of NAD+, a coenzyme that plays a vital role in various cellular functions. On the other hand ...

These are products that contain either NAD+ itself or its precursors, nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN). These precursors are converted into NAD+ inside the cells.

As we age, NAD+ levels can decline by over 50% by midlife, leading to a host of degenerative changes: fatigue, cognitive decline, joint pain, poor skin quality, and slow metabolism. To counteract this ...

she recommends NAD precursors (like NR or NMN by prescription or from third-party tested brands like Tru Niagen or Pure Encapsulations) for oral supplementation, but pure NAD+ for subcutaneous ...
