SmartHerb is an independent supplement-shopping companion that helps consumers track prices and make more informed purchasing decisions on iHerb. Its price tracker monitors selected products around the clock, sends email alerts when prices reach a user’s target, and provides price history charts. Shoppers can track up to 30 products for free and receive notifications when items are back in stock. The Best Value Finder compares supplements by nutrient content per dollar, helping users assess value across products.

SmartHerb is available through a Chrome extension and a web dashboard. The extension displays price history on iHerb product pages and supports one-click price alerts, while the dashboard lets users manage tracked products and notification preferences. Its AI Supplement Advisor offers personalized product suggestions, comparisons, and health-related answers described as evidence-based and informed by NIH medical research. SmartHerb also provides health and weight-control tools. Some features, including stock notifications and price history, are listed as coming soon on the site.
