About Coupon Science

We’re obsessed with health! We’ve been buying supplements online about as long as the internet has made it possible. Starting over 20 years ago, we discovered iHerb and began buying almost exclusively from them because of the amazing prices, vast selection, low-cost shipping, and amazing service.

A few short years later, we started participating in the iHerb Rewards program, and now in 2024 are proud to offer you the latest deals and product recommendations.

At Coupon Science, we are driven by 3 primary objectives:

  • Share the best health coupons and promo code discounts in the vitamin and supplement space. We proudly support iHerb.

  • Share original research pieces (we strive to publish 1-2 year) on coupon usage in the United States and around the world.

  • Recommend the most popular health supplements.

Today, we are primarily focused on vitamin and supplement coupons, promo codes, and discounts, while we also publish new research articles each year.
