The iHerb Affiliate Program lets you earn up to 10% commission on every sale from one of the world’s most trusted online health supplement retailers. iHerb ships to over 185 countries, carries more than 30,000 products across vitamins, supplements, herbs, protein powders, beauty products, and natural foods, and has processed over 150 million orders globally.

Commission rates are tiered based on monthly revenue: affiliates start at 5% and progress up to 10% as their monthly referral revenue increases. The program is managed through Impact Radius, providing affiliates with real-time tracking, promotional banners, deep links, and monthly performance reporting. iHerb’s extremely competitive pricing and regular promotional discounts contribute to strong conversion rates across health and wellness audiences worldwide.

One consideration is the 7-day cookie window, which is shorter than average. However, iHerb’s repeat purchase model means returning customers who already have your affiliate code continue generating commissions on subsequent orders. The $20 minimum payout is very accessible, and the Impact Radius platform ensures reliable payment processing via PayPal, bank transfer, or Payoneer.
