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.
