Healthline Nutrition publishes credentialed, partially hands-on supplement roundups, but every ranking carries affiliate links and the site's own "About" page acknowledges affiliate and sponsored-content revenue, making full editorial independence from the products it ranks structurally impossible.
What it's really for Drive affiliate-linked purchases of health and nutrition products through credentialed editorial content
What our grade covers The grade on this page is about Best-of supplement roundups (protein powders, multivitamins, fish oil, etc.) evaluated by staff dietitians and editors, not everything the site does.
High Scoring Confidence Checked against primary sources. We are confident in the facts and the grade here.
Healthline's own "About" page states the site receives funding from "advertisements, sponsored content, and other partnerships, such as affiliate programs." Every best-of roundup article carries an explicit "If you buy through links on this page, we may earn a small commission" disclosure. Parent company Red Ventures (now RVO Health) is a performance-marketing company whose core business is affiliate and lead-gen revenue, creating a structural incentive to rank products that convert at high affiliate rates.

- What it costs you
- Free to read The reviews are free to read.
- How they make money
- Affiliate commissions on reader purchases (Amazon and brand direct), display advertising, and sponsored content partnerships. Parent RVO Health is a performance-marketing company.
- What they do
- Publishes staff- and dietitian-written "best of" supplement and nutrition product roundups. Editors and registered dietitians select and, in some cases, personally test products, then rank them with affiliate links to Amazon and brand sites throughout.
- What to watch for
- Does not conduct independent lab testing on products — third-party testing is a selection criterion (i.e., they favor products that carry third-party certifications) rather than something Healthline performs itself. Personal tasting/mixability tests by staff are not blinded or standardized. Rankings cannot be verified as free of commercial pressure given the affiliate revenue model.

How the grade was reached
Does the site take money from the very entities it ranks? Pay-for-placement, vendor-funded data, and affiliate commissions all pull this down. The less the ranking can be bought, the higher the score.
What is the ranking actually built on? Hands-on testing scores highest, then verified first-hand reviews, then opinion or popularity surveys and self-reported figures, then pay-to-rank, which scores lowest.
Is the methodology published, specific, and reproducible? Can a reader see how a given rank was reached, or is it a black box?
Are commercial relationships, sponsorships, and affiliate arrangements disclosed clearly and near the rankings themselves, rather than buried?
How hard is it to game? Controls against fake reviews, solicited reviews, and vendor gaming raise this; an open box anyone can stuff lowers it.
