Affiliate disclosure & how we rate

Guayusa Field Guide is a participant 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. As an Amazon Associate, we earn from qualifying purchases. Amazon and the Amazon logo are trademarks of Amazon.com, Inc. or its affiliates.

Prices and availability shown are captured at a point in time and are not guaranteed — always confirm the current price on Amazon before buying.

How we rate

We pull manufacturer facts first — format, weight, certifications, steep instructions — from the listing and the brand's own site. Where a spec is missing, we say so rather than invent a number. The six editor scores (energy, purity, value, ease of use, flavor, sustainability) are computed from those facts across this catalog and are clearly labeled as editorial judgment, never a manufacturer spec.
