iHerb

iHerb is a premier global e-commerce destination specializing in natural health and wellness products. Since its founding in 1996, the brand has expanded its catalog to include over 50,000 items from more than 2,000 trusted brands, spanning categories such as vitamins, minerals, sports nutrition, beauty, and grocery. For affiliates, iHerb offers a highly credible platform with a global reach, shipping to over 180 countries and supporting dozens of localized storefronts and currencies. This international presence makes it an ideal partner for content creators and publishers with diverse, global audiences.

The iHerb Affiliate Program is managed through major third-party networks, primarily Partnerize, though it may also be found on platforms like Awin or CJ depending on the region. The program is distinct from the iHerb Rewards program; while Rewards is designed for individual customer referrals, the Affiliate Program is tailored for professional publishers, influencers, and commercial sites. Affiliates benefit from a high-converting website—reported at approximately 7.9%—and a vast inventory that allows for deep linking to specific wellness solutions, from vegan supplements to K-beauty products.

Commission tracking is based on a 7-day cookie window, meaning sales must occur within a week of the last click to be credited. While the base commission rate is typically around 5%, the program emphasizes potential for higher earnings through exclusive incentives and high-volume performance. Payouts are generally distributed 45 days after the close of the month in which the conversion was approved. Affiliates are prohibited from using their own links for personal purchases and must adhere to strict guidelines regarding paid search and trademark bidding. The program provides a robust suite of tools, including an API for large-scale publishers and advanced reporting dashboards to monitor traffic and conversion metrics effectively.
