Compare supplement value based on specific nutrients. Find products that give you the most mg, IU, or mcg per dollar spent.
Try Best Value FinderEver wondered if you’re getting the best deal on your Vitamin D or Magnesium? The Best Supplement Value Finder helps you compare products based on nutrient content per dollar - not just the price tag.
Instead of comparing prices, we compare how much actual nutrient you get for your money. This means you can find products that offer 2x or even 3x more value than what you’re currently buying.
The Best Value Finder uses a simple 3-step process to help you find the best supplement deals:
Start with any iHerb product you’re currently taking or considering. Just paste the product URL or ID.
The tool will automatically extract all the nutrients from the product’s Supplement Facts label - everything from Vitamin C to Zinc.
Select which specific nutrient you want to compare. For example:
The tool shows all available nutrients in the product, sorted by amount (highest first), making it easy to pick what matters most to you.
Get instant results showing the top 15 best-value products for that specific nutrient, ranked by amount per dollar.
Each result shows:
The #1 best value product is highlighted with a “Best Value” badge and green border.
Our algorithm calculates: (nutrient amount per serving × servings per container) ÷ price = amount per $1. Higher is better!
The #1 ranked product is clearly highlighted with a "Best Value" badge and distinctive green styling so you know exactly which product offers the most value.
See amount per serving, total amount, price per serving, and cost per unit (mg/IU/mcg) to make informed decisions from multiple angles.
Works with any nutrient in the Supplement Facts panel - vitamins, minerals, herbs, amino acids, and more. Compare exactly what matters to you.
You’re taking a product with 5,000 IU per serving at $15.99 for 120 capsules.
Using Best Value Finder, you discover:
The best value product gives you 3.9x more Vitamin D3 for your money! Even though it costs more upfront, you’re getting much better value.
Many shoppers focus solely on the price tag, but a cheaper product often contains less of the actual nutrient. A $10 product with 100mg per serving might be a worse deal than a $20 product with 500mg per serving.
When you buy based on value instead of price, you often get larger bottles that last longer. This means:
No! Best value means the most nutrient per dollar. A $20 product can have better value than a $10 product if it contains significantly more of the nutrient you're comparing.
Yes! The tool compares all iHerb products containing the selected nutrient, regardless of brand. This helps you discover great value products you might not have considered.
The tool uses the total amount listed in the Supplement Facts panel. For example, if a product lists "Magnesium (as Citrate and Oxide) 400mg", it uses 400mg for comparisons.
Prices are updated daily from iHerb. However, flash sales and promotions may cause temporary differences. Always verify the final price on iHerb before purchasing.
Products may be missing if: (1) they're out of stock, (2) they don't contain the specific nutrient you're comparing, (3) nutrient data isn't available in our database yet, or (4) they're not in the top 15 by value.
Our tool focuses on quantity per dollar, but quality absolutely matters! Use the tool to find high-value options, then research the specific brands, forms (e.g., methylated B12), and third-party testing to make a fully informed decision.
Stop overpaying for nutrients. Use the Best Value Finder to discover products that give you more bang for your buck.
