Longevity
Compounds and mechanisms studied for slowing cellular aging — NMN, resveratrol, autophagy.
4.1NMN (Nicotinamide Mononucleotide)
An NAD+ precursor intensively studied in the context of cellular aging — human data are still early, despite huge market popularity.
3.9Resveratrol
The red-grape polyphenol famed as a 'sirtuin activator' — but its bioavailability in humans is very low, which limits the practical relevance of many striking test-tube results.
4.3Autophagy
An intracellular 'housekeeping' process that clears out damaged proteins and organelles, whose discovery earned a Nobel Prize — one of the key mechanisms studied in the context of slowing aging.
4.4Telomeres and Telomerase
Protective 'caps' on the ends of chromosomes that shorten with every cell division — one of the most recognizable, though still imperfect, biomarkers of cellular aging.
