Affiliate Disclosure

Optimize Your Biology is reader-supported. When you buy through links on our site, we may earn a commission, at no additional cost to you. We participate in the Amazon Services LLC Associates Program and other affiliate programs, which let us earn fees by linking to retailers like Amazon and others.

Here is how we handle that responsibility:

  1. We only link to what we believe is the best. We never recommend or rank a product because it has a good affiliate program. The data and our testing decide, not the payout.
  2. We happily link to things we earn nothing from. If the best option cannot be affiliated, we link it anyway, because the point is to give you the best information, not to get paid.
  3. We pass along deals when we find them. When we can share a coupon or code to get you a better price, we do. Sometimes that earns us a little, often it is just a deal we found and wanted to give you.

So if this site helps you, and you want to support us, buying through our links is a real and direct way to do it. Either way, we only ever recommend what we find to be genuinely the best.

You will also find personal donation links for Derek and me inside our articles. If you would rather support us that way, any donation is greatly appreciated, and it goes straight to the two of us.
