Affiliate disclosure

We may earn a commission when you buy through our links, at no extra cost to you.

How it works

Many links on HealthWorld are affiliate links. If you click one and make a purchase, the retailer may pay us a small commission. You pay exactly the same price you would otherwise.

We currently participate in, or may participate in, the following programs:

  • eBay Partner Network
  • Amazon Associates — As an Amazon Associate I earn from qualifying purchases.
  • Other retailer and brand affiliate programs, which we will list here as we join them

Our editorial rules

  • Brands cannot pay to be included or to rank higher.
  • We do not publish star ratings, review counts or testimonials we did not collect ourselves.
  • Product facts come from the product label; certifications are listed only when we are confident they apply.
  • Links on product pages go directly to the retailer — we never hide where a link leads.
