In plain terms: Some links on HealthSpan40.com are affiliate links. If you click one and make a purchase, we may earn a small commission — at no extra cost to you. This is how we keep the site free and independent.

Why We Use Affiliate Links

Researching and writing evidence-based guides takes real time. Affiliate commissions help fund that work without charging readers or relying on intrusive ads. We only link to products or services we believe are genuinely relevant to the topic at hand.

Our Editorial Independence

Whether or not a product is discussed on this site is never determined by commission rates. Our process, as described on our About page, starts with the research question, not the product. If a product doesn’t hold up under the research, we say so — commission or not.

What This Means When You Click a Link

• Clicking it may set a cookie that tells the retailer or affiliate network the referral came from HealthSpan40.
• If you complete a qualifying purchase (usually within a set time window set by the retailer), we may earn a commission.
• The price you pay is the same whether or not you use our link.
• We do not have access to your payment information or personal purchase details — that is handled entirely by the retailer.

Programs We Participate In

HealthSpan40.com works with affiliate networks and merchants including CJ Affiliate. This list will be updated as we join new programs.

Not Everything Is an Affiliate Link

We also link to non-commercial sources — NIH, Mayo Clinic, Harvard Health, peer-reviewed studies, and other references — purely for citation purposes. These are never affiliate links and we receive no compensation for them.
