iHerb is a globally recognized health and wellness retailer with a massive product catalog spanning supplements, skincare, hair care, and more. The 5% revenue share commission is modest compared to many competitors in the health and beauty space, which is the program's most notable weakness. However, iHerb compensates with exceptional brand trust, high conversion rates, and a loyal customer base that frequently places repeat orders. The platform ships to over 180 countries, making it ideal for affiliates with international audiences. Supplements is where iHerb truly excels, as it is one of the top destinations for vitamins and natural health products. The makeup and hair loss categories are less of a core focus, with a smaller selection than specialty retailers. For content creators in the wellness and supplement niche, iHerb is a reliable earning option despite the lower commission rate. Affiliates should focus on volume-based strategies, as individual order payouts will be relatively small.
