Longevity content on the open internet is overwhelmingly written for a male audience. The default stacks circulating across Reddit, podcasts, and influencer channels assume a hormonal environment most women do not have from their late thirties onward. Three shifts matter for women specifically.[01]
First, oestrogen's decline through perimenopause affects mitochondrial function, cellular wellbeing, and the maintenance of normal bones — the same systems most longevity supplements target. Second, women maintain muscle mass differently after 40, which makes the maintenance of normal muscle function a primary longevity consideration. Third, women's heart-health dynamics shift as oestrogen's effects wane, which changes the weighting of heart-relevant interventions. This guide is written for women navigating those shifts.
What the research examines
Three areas have enough trial maturity to write about with confidence: CoQ10 absorption (ubiquinol versus ubiquinone), EPA and DHA at the doses the cardiovascular literature examines, and creatine across the lifespan including the menopausal transition.[03] A fourth area — polyphenols and NAD+ precursors — is research-context only: there are interesting trials, but no UK authorised health claims, so we describe what the studies examine without making benefit statements. Solgar UK does not stock either creatine or NMN; we flag both gaps explicitly rather than substitute brands we have not evaluated against the same three criteria.
