Browse the iHerb site and you'll find more than 1,200 brands and 30,000 brand name products which you may also find at health food stores and natural pharmacies. However, there is one important difference: their prices are typically 30-50% less. When buying natural products, it is always important you shop major national brands which are sold on various websites, in addition to the retail channels. Such brands have a dedicated quality control team and have invested heavily to monitor quality. iHerb deals directly with some of the largest and most respected brands in the world.
