Affiliate Disclosure

This page explains how StackSpan uses affiliate links, how we earn revenue, and our commitment to providing honest, unbiased supplement recommendations regardless of affiliate relationships.

Last updated: April 2026

🛒 What This Means For You

StackSpan contains affiliate links. If you purchase a product through one of these links, we may earn a small commission — at absolutely no extra cost to you. The price you pay is the same whether you use our link or go directly to the retailer.

We only recommend products we genuinely use and believe in. Our affiliate relationships do not influence our recommendations, editorial content, or supplement selections. If a brand doesn't meet our standards, we won't link to them — affiliate commission or not.

How Affiliate Links Work

When you click an affiliate link on StackSpan and purchase a product, the retailer credits us with referring you. They pay us a small percentage of the sale as a referral fee. This is a standard practice used by millions of websites and review platforms.

What stays the same for you:

No extra cost — you pay the exact same price as you would without our link
Same product, same quality, same return policy
Same customer service and support
No obligation to use our links — you're free to purchase anywhere

What changes for us:

We earn a small referral fee that helps fund the site
We can continue providing free, honest supplement research
The business becomes sustainable without charging you extra

FTC Compliance

StackSpan complies with the Federal Trade Commission's guidelines on affiliate marketing. This means:

All affiliate links are clearly disclosed with a sponsored attribute and visible disclosure banners
We disclose affiliate relationships at the top of every page containing affiliate links
We never hide or obscure affiliate relationships from readers
We do not receive free products or special treatment from brands in exchange for reviews

\"The FTC's endorsement guidance says that if an advertiser compensates an endorser, the material connection must be clearly and conspicuously disclosed. The guidance applies to all forms of endorsements, including online reviews, blog posts, and social media posts.\"

Every affiliate link on StackSpan includes the rel=\"sponsored\" attribute, which signals to browsers and ad blockers that this is a compensated link. Product links (non-affiliate) do not include this attribute.

Our Editorial Standards

Affiliate revenue does not influence our recommendations. Our supplement selection process is based on:

Published peer-reviewed research (PubMed, clinical trials)
Personal use and real-world experience
Brand quality, third-party testing, and transparency
Value for money relative to effective dosage

We will never recommend a supplement solely because it has an affiliate program. If a brand doesn't meet our standards — regardless of commission rate — we don't link to them.

If we ever review a product we receive free samples of, we will disclose this explicitly and our review will reflect our honest experience, positive or negative.
