You're Probably Overpaying for Protein Powder 🇬🇧
Here's the one number supplement companies hide—and why they don't put it on the label.
Here's the one number that reveals what protein actually costs: price per 100g of actual protein. Brands don't put this on the label because it reveals expensive tubs often contain the same protein as budget options.
The supplement industry would rather you compare tub prices and serving counts than tell you the one number that matters: price per 100g of actual protein.
When you do the math, expensive "premium" protein powders often cost 2-3x more per gram of protein than budget options—with identical nutrition specs. You're paying for marketing, not better protein.
This table shows 54 protein powders in United Kingdom ranked by price per 100g of protein. We also show calories per 100g of protein to help you find the most efficient options. Use the filters to find protein powders that match your preferences for type, flavor, and sweetener.
