Who runs this site

HealthSpan40 is written and maintained by the HealthSpan40 Editorial Team. We are not a hospital, a clinic, or a substitute for your doctor — we are researchers and writers who read the primary sources (NIH, PubMed, Mayo Clinic, Harvard Health, CDC) so you don’t have to dig through them yourself. Where a topic carries real medical risk, we plan to add a “Reviewed by” credential from a licensed clinician before publishing — we won’t claim a review that didn’t happen.

How we research every guide

Before we publish anything, we check three things: first, that the topic reflects a real, common question people over 40 actually search for — not something we simply found interesting. Second, that every statistic traces back to a non-affiliate source: government agencies, medical institutions, or independent research bodies — never a company we might earn a commission from. Third, that the page hasn’t already been covered elsewhere on the site; we’d rather improve an existing guide than publish a near-duplicate.

How we handle supplements and products

We only recommend products in categories with reasonable evidence behind them, and we say clearly when the evidence is mixed. We do not accept payment in exchange for a positive review, and we do not inflate ratings to match an affiliate partner’s expectations. If we haven’t personally tested a product, we say so.

Affiliate disclosure

Some links on HealthSpan40 are affiliate links. If you click through and make a purchase, we may earn a commission — at no extra cost to you. This never influences which products we choose to feature or how we rate them. Our writing and our affiliate relationships are handled separately, on purpose.
