Crook 1991 (Neurology, N=149 age-associated memory impairment): PS 300mg/day × 12 weeks produced statistically significant reversal of age-related cognitive decline — participants performed as if they were 12 years cognitively younger on a combined neuropsychological battery (name-face recognition, story recall, learning). PS is a phospholipid component of the inner leaflet of the plasma membrane. It activates PKC, supports synaptic transmission, promotes neuronal repair, and attenuates cortisol response to exercise stress (Monteleone 1990, 800mg PS). Soy-derived PS was replaced by sunflower PS in most products after BSE (mad cow) fears in the 1990s; sunflower PS appears bioequivalent. https://longevitylab-roan.vercel.app/nmn-vs-nr-nad-precursor-guide https://longevitylab-roan.vercel.app/nmn-vs-nr-nad-precursor-guide Thu, 09 Jul 2026 00:00:00 +0000 A science-backed comparison of NMN and NR — the two leading NAD+ precursors.

When telomeres shorten below a critical threshold (~4kb), TRF2 (telomere repeat factor 2) can no longer maintain the T-loop structure, the Shelterin complex disassembles, and the chromosome end is recognized as a double-strand break by ATM/ATR kinases — triggering DNA damage response (DDR) → p53 activation → cell senescence or apoptosis. Telomerase (TERT + TERC) reverse-transcribes the RNA template onto the chromosome 3' end, extending telomeres — active in germline cells, stem cells, and cancer cells, but silenced in most somatic cells post-development. Lifestyle factors with strongest evidence for telomere length: aerobic exercise (+), chronic stress (-), obesity (-), Mediterranean diet (+), smoking (-). https://longevitylab-roan.vercel.app/telomeres-blackburn-greider-hayflick-limit-tert-ta65-longevity-guide https://longevitylab-roan.vercel.app/telomeres-blackburn-greider-hayflick-limit-tert-ta65-longevity-guide Thu, 09 Jul 2026 00:00:00 +0000 Elizabeth Blackburn, Carol Greider, and Jack Szostak won the 2009 Nobel Prize in Physiology for discovering how telomeres protect chromosomes and how telomerase rebuilds them.
