Unit Price for iHerb – Smart Value Comparison

Compare iHerb brands and package sizes by weight, dose, capsule count and the amounts of supported active ingredients.

iHerb's "per serving" prices depend on the serving size defined by each brand. One product may contain 1 g per serving, another may contain 5 g, while another may require 6 capsules per serving. Comparing serving prices alone may therefore give a misleading comparison across brands. This extension automatically converts prices into consistent units and displays them directly on product listings and product pages, making it easier to compare brands, package sizes, and product forms. • 💊 Supplement dosage: per 100 mg / 100 mcg (supports IU conversion) • ⚖️ Solid weight: per 100 g / 1 kg / 1 oz / 1 lb • 💧 Liquid volume: per 100 ml / 1 L / 1 fl oz • 🔢 Price per capsule / tablet (optional) • 🧪 Active-content prices: compare the actual amounts of supported active ingredients separately from package weight. Examples include protein, fish oil EPA + DHA, creatine, collagen, and selected amino acids (requires a recognizable Nutrition or Supplement Facts table). • 💎 Mineral pricing: distinguishes elemental amounts from source-compound weights and supports amounts below 1 mg. • 🏆 Automatically compares package options and highlights the best value • 🔍 Deep Scan (optional): reads product facts tables in the background so listing pages can also display active-content prices. Slower to process. • 💱 Automatic currency detection, including HKD, TWD, USD, and more • 🌐 Interface available in Traditional Chinese / English / Cantonese Smart parsing: reads product titles and facts tables, distinguishes "per serving" from "per unit", and normalizes units for easier comparison. Extra active-content prices focus on the product's main ingredient to avoid including unrelated nutrients. If information is missing or a value appears implausible, the extension may omit the result. Serving counts for unselected package options may be estimated from the current product's content and weight ratio. Selecting a package recalculates the result using the facts available on that product page.
