How we rank protein powder
The Supp Hub is an independent price-comparison aggregator — we don't sell stock, so the ranking isn't influenced by which retailer pays us. Default sort is cost per serve (total price divided by servings per container). For whey buyers chasing the cheapest gram of protein, the cost per 100g of protein sort uses the label's protein per serve to normalise across products of different concentrations.
What to look for when buying protein powder
- Protein per serve: 20–25g is the standard for whey isolates and concentrates; vegan blends sit at 18–22g.
- Cost per 100g of protein: the only number that lets you compare a 1kg whey isolate against a 2kg concentrate fairly.
- Sweetener and additives: sucralose vs stevia vs unflavoured matters more for tolerance than for performance.
- Third-party testing: Informed Sport / NSF certification matters if you're a tested athlete — we surface these badges on each product page.
Prices are pulled from retailer product pages and updated daily. Out-of-stock listings are excluded from the ranking. Some links are affiliate links — they never affect your price or the order shown.
