Aged garlic compound nudges the fat-brain-muscle axis longevity researchers chase
A new Cell Metabolism paper identifies S-1-propenyl-L-cysteine, a bioactive in aged garlic extract, as an upstream activator of LKB1 that prompts fat tissue to release more eNAMPT. In aged mice, the molecule reduced frailty and improved muscle force. The human data is preliminary.
NMN and NR supplements: what the evidence says about NAD precursors and aging
NAD levels drop by roughly half between age 40 and 70, and supplement companies are selling NMN and NR as the solution. The human trials show measurable NAD increases but inconsistent clinical benefits, and the regulatory situation for NMN remains unsettled.
Low-dose oral NMN was safe and moved platelet counts in a phase 1/2 ITP trial
A 25-patient phase 1/2 trial published in Nature Medicine found that low-dose oral NMN was well tolerated in adults with steroid-refractory immune thrombocytopenia, with 20 percent meeting the primary platelet-response endpoint and 52 percent maintaining responses through week 8.
NMN versus NR: what the 2025 evidence actually says
A 2025 Food Frontiers review compares NMN and NR head to head: both raise blood NAD+, but the human trial record falls short of the longevity-extension claims printed on the supplement box.
