Rachel Kim
How NAD⁺ actually works in a cell — and where the mechanism story gets ahead of the human data.
Rachel Kim is a pen name used by a writer at NAD Picks. Rachel writes about NAD⁺ biochemistry: the salvage pathway, how NR and NMN differ on the way in, what sirtuins and PARPs consume, and the recurring pattern in this category where a plausible mechanism is sold as a demonstrated result.
What they cover
- NAD⁺ biosynthesis and the salvage pathway
- Nicotinamide riboside versus nicotinamide mononucleotide
- Sirtuin and PARP enzymology
- Mitochondrial energy metabolism
- Coenzyme chemistry and cellular redox
- Mechanism-versus-evidence evaluation
