About SupplementPricer

Our Mission

We believe nobody should overpay for supplements. The same product can vary by 40% or more across different retailers. SupplementPricer makes it easy to compare prices and find the best deal in seconds.

How We Work

We track prices for popular supplements across 6 major retailers: Amazon, iHerb, Vitacost, GNC, Bodybuilding.com, and Swanson Vitamins. Our system checks prices daily and calculates the per-serving cost so you can make apples-to-apples comparisons.

Methodology

• We compare the exact same product (same brand, same count, same formulation) across retailers
• Per-serving cost is calculated as total price ÷ number of servings per container
• Prices are updated daily and reflect the standard retail price (not subscribe-and-save or special promotions)
• We highlight the best price and calculate the savings vs. the most expensive option

Revenue

SupplementPricer is free to use. We may earn affiliate commissions when you click through to purchase from a retailer. This never affects our rankings — the cheapest price is always highlighted regardless of affiliate arrangements.
