Gut microbes may dictate cellular aging, new review suggests
A Frontiers in Aging review introduces the microbiome‑gerogene axis, proposing that gut microbes act as upstream regulators of cellular aging networks. Age‑related dysbiosis reduces key metabolites, leading to leaky gut, chronic inflammation and epigenetic drift that accelerate organ decline. The authors highlight precision interventions such as ellagitannin‑derived urolithin A and fermentable fibers to restore microbial balance.
Taking a Multivitamin Could Slow some Signs of Aging, New Study Suggests
A randomized clinical trial of 958 adults aged 60 and older found that a daily multivitamin‑multimineral supplement modestly slowed two epigenetic aging clocks over two years. The clocks’ rate of increase decelerated by roughly 1.5 to 2 months per year compared with placebo. While the effect was observed in PCPhenoAge and PCGrimAge, three other clocks showed no significant change. Researchers caution that the findings are preliminary and call for additional studies to confirm any longevity benefits.
Low‑Dose Lithium Orotate May Counteract Alzheimer’s Deficiency
We’ve spent decades treating lithium as a heavy duty psychiatric tool. New evidence suggests it’s actually a foundational brain nutrient and that Alzheimer’s may essentially be a localized lithium deficiency. By using the Orotate salt, we can bypass plaque-induced transport...

Balancing Muscle Reserves and VO2max in Aging
In my view, the competing forces when it comes to health/longevity... 1/ Having sufficient reserves (both energy and muscle) so that you're not frail. 2/ Having very strong aerobic/metabolic fitness. These start to go against each other as you age. For example, for an...
Want Better Sleep? The Dutch Method Is Counterintuitive—But Science Says It Works
