Best Online Stores

What supplements do I need? We cannot tell you. But we provide you with principles (see How to Choose: 3 Steps). We also narrow down your brand search from a few hundreds to less than 30 (see Popular Brands or Premium Brands). Now comes the last question: where to buy? We have a straight answer for you: iHerb.

For many supplement shoppers, iHerb remains one of the largest and most established online destinations focused on health and wellness products. iHerb says it offers 50,000+ top-rated health and wellness products from trusted brands, and the company now serves customers around the world with localized country, language, and currency settings.

Founded in 1996 and headquartered in Irvine, California, iHerb has grown into a major global e-commerce retailer in the supplement and wellness space. The company says it ships to customers in 185+ countries, and its corporate materials highlight broad international support across multiple languages, currencies, and payment methods. In January 2026, iHerb also completed its acquisition of Vitacost.

One reason iHerb stands out is its international shopping experience. Users can adjust their country or region, language, and currency settings directly in the account interface, which helps tailor product availability, pricing, and shipping options. The site also supports browsing by category, brand, and health topic, making it easier to filter a very large catalog down to products that fit specific needs.

iHerb also emphasizes product handling and logistics. The company says orders are shipped from multiple climate-controlled fulfillment centers and warehouses in the U.S. and Asia, designed to help protect freshness and product quality during storage and shipping.

Customer support and post-purchase policies have also evolved. iHerb currently offers customer help through its Help Center, virtual assistant, and live chat, with live chat hours listed on its contact page. Its refund policy now generally allows returns for most products within 30 days, while many iHerb brand items purchased on its site are eligible for a 90-day return window.

If you want a current reputation signal, ConsumerLab’s 2026 survey results identified iHerb as the top-rated Online Supplement Retailer on overall consumer satisfaction.
