NMN, NAD+, and Resveratrol: What the science actually says about slowing ageing

NMN, NAD+, and Resveratrol: What the science actually says about slowing ageing

Current evidence suggests NMN/NR can raise NAD+ markers in blood and may aid metabolic health in some small studies, but there's no convincing proof they slow ageing or preserve muscle or cognition in older adults; resveratrol has shown effects in lab studies but poor bioavailability and mixed human results limit its anti-ageing claims. The biology is plausible, but real long-term benefits are unproven, and the best proven ways to support healthy ageing are regular exercise, good sleep, a balanced diet, and managing chronic conditions.

Goldilocks sleep window tied to slower ageing in half a million people

Goldilocks sleep window tied to slower ageing in half a million people

A large UK Biobank analysis of about 500,000 adults links six-to-eight hours of nightly sleep with slower biological ageing and lower risk of early death and disease, across 23 ageing clocks in 17 organs; sleeping more or less than this window associates with faster ageing, though the study does not prove causation and individual optimum sleep may vary.

Chronic stress and everyday habits that accelerate ageing

Chronic stress and everyday habits that accelerate ageing

A study highlighted in PNAS links chronic stress from a difficult social contact (a “hassler” in your circle) to about nine months of extra biological ageing, with faster cellular ageing. Additional common habits associated with ageing include irregular sleep schedules, poor gut health, doom-scrolling short videos, overly routine daily life, prolonged sitting, and negative self-talk—each impacting sleep, inflammation, and brain function. Experts suggest fostering supportive relationships, maintaining a regular sleep pattern, improving gut diversity through fiber and fermented foods, challenging the brain with new tasks, breaking up long sitting periods, and reframing negative thoughts to protect against age-related decline.

A penny-a-day pill could slow ageing, says professor who now takes it

A penny-a-day pill could slow ageing, says professor who now takes it

COSMOS trial analyses suggest a daily multivitamin may slow biological ageing in older adults, with DNA methylation markers showing participants on vitamins were about three months biologically younger than placebo after two years; earlier results also noted cognitive benefits from addressing subtle micronutrient gaps. The author, Professor Rob Galloway, now takes a multivitamin and argues the cheap, low‑risk option is reasonable, though the findings apply to older adults (men 60+, women 65+) and may not extend to younger people. The piece underscores nutrition as a potentially major determinant of long‑term health, while acknowledging more research is needed; it also touches on meningitis B vaccination policy for teens in light of evolving risk.

Language Shifts in Ageing: Normal Slowing or Early Dementia Clues?

Language Shifts in Ageing: Normal Slowing or Early Dementia Clues?

Health experts say some language changes are normal with ageing (slower speech, occasional word-finding pauses), but dementia more typically causes loss of words and meanings, vaguer wording, and reduced coherence years before symptoms. There is no single diagnostic test yet; however, advances in language-analysis tools and apps may help flag risk earlier to enable timely intervention.

Active days, longer life: a fish’s behavioural clock predicts lifespan

Active days, longer life: a fish’s behavioural clock predicts lifespan

Scientists tracked 81 African turquoise killifish from adolescence to death with 24/7 video and a machine-learning model, finding that more active, faster-moving fish tended to live longer and those that slept mainly at night also reached older ages, while daytime napping correlated with shorter lifespans. The study suggests early-life behaviour can forecast ageing long before disease signs emerge.

Daily multivitamin slows ageing markers in older adults, study suggests

A two-year, randomized COSMOS trial found that taking a daily multivitamin slowed certain epigenetic clocks of ageing in people around 70, reducing biological age by about four months versus non-users; the effect was more pronounced in individuals with accelerated ageing and was observed in two of five DNA methylation clocks linked to mortality risk. While promising, the authors emphasize the effects are small and do not yet imply improved clinical outcomes.

Immunologist Reveals 9 Supplements to Slow Aging and Boost Immunity

Immunologist Reveals 9 Supplements to Slow Aging and Boost Immunity

UK immunologist Dr. Jenna Macciochi recommends a nine-supplement routine—including CoQ10, omega-3 and 7, vitamin D and K, creatine, taurine, magnesium, gut support, spermidine, quercetin, and fisetin—to support healthier ageing, boost immunity, and improve energy and cellular repair, especially for those in their 40s and 50s. These supplements should complement a balanced lifestyle, not replace it, and always under medical guidance.
