Affiliate Disclosure
Last updated: March 2026
How We Earn Money
rx-digestion.com is a free resource. We earn money through affiliate partnerships — when you click a link on our site and make a purchase or sign up for a service, we may receive a commission at no extra cost to you.
We participate in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. We also have direct affiliate relationships with probiotic/synbiotic brands and at-home gut-testing companies.
What We Earn From Each Partner
Unlike most affiliate sites, we believe you deserve to know exactly what we earn. Below is every brand we link to. Where a program is not live yet we link to the brand directly and earn nothing — those rows say so rather than quoting a rate we are not being paid:
| Partner | What We Earn | Type |
|---|---|---|
| Seed | Nothing — no affiliate relationship yet | Synbiotics |
| Ritual | Nothing — no affiliate relationship yet | Synbiotics |
| Pendulum | Nothing — no affiliate relationship yet | Probiotics |
| Viome | Nothing — no affiliate relationship yet | Gut Testing |
| Zoe | Nothing — no affiliate relationship yet | Gut Testing |
| Thorne | Nothing — no affiliate relationship yet | Gut Testing |
| FoodMarble | Nothing — no affiliate relationship yet | Breath Testing |
| Nerva | Nothing — no affiliate relationship yet | IBS App |
| Amazon | 1-4%/sale per sale | Products |

Editorial Independence
Our affiliate relationships do not influence our rankings, recommendations, or editorial content. We never accept payment to rank a product higher. When the cheapest option is also the best, we say so — our #1 probiotic pick is a store-brand option, which pays us the lowest commission of any brand we review.
We disclose our commission on every affiliate link throughout the site, not just on this page. If you see a “Check Price” or “Visit” button, there will be a line below it telling you exactly what we earn if you click through and buy.
FTC Compliance
In accordance with the Federal Trade Commission's 16 CFR Part 255 guidelines on the use of endorsements and testimonials in advertising, we disclose the following:
- Any product or service reviewed on this site may generate affiliate revenue for rx-digestion.com.
- All opinions expressed are our own and are not influenced by compensation.
- We only recommend products and services that we believe provide value to our readers.
- Individual results from any product or treatment may vary. Nothing on this site constitutes medical advice.
