Why iHerb is the best online store to buy supplements

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.

Indeed Amazon is the dominant shopping website in the U.S. with seemingly unlimited choices of  supplements. However, when it comes to supplements, there are two very popular specialty online stores: iHerb and Vitacost. Both carry 35,000+ products and more than 1,200 brands. While they are similar, iHerb is a better choice, offering multi-language service such as Chinese, and most importantly,  providing extremely competitive prices (10 – 40 % lower prices than brick-and-mortar stores) and special shipping & handling (such as air-conditioned warehouse to ensure freshness of goods). Other online stores, such as LuckyVitamin, Swanson, eVitamin, operate at much smaller scale. According to Alexa web traffic statistics, iHerb ranks 1,120 vs Vitacost’s 2670.

In business since 1996, iHerb is now a world-class online store, supplying a vast selection of brand name natural products, offering the best value to customers globally. iHerb is headquartered in Irvine, California. For six years in a row, iHerb has been named #1 online supplement store by ConsumerLab.com.

iHerb provides a well designed, responsive website. For example, you can customize your shopping experience by choosing your country flag, language (12 languages) and prices in currency you want (55 of them). You can search products through categories, brands, health topics, package quantity, form, and price range. Shopping cart is also nice, big and visible in upper right corner. Costumer service is fast in responding on Live Chat. You can return any product within 60 days of being purchased.
