How to read the table
The big number is the price per kg of protein; underneath is the cost of 30 g of protein, about one large scoop. A powder at 2× the per-kg price costs you twice as much per shake, no matter how big the tub.
Three things that change value
- Pack size: bigger packs usually win, as long as you will finish them before the best-before date.
- Sales: prices move often. We re-check every day; the order on this page reflects today's prices.
- Protein %: fillers, sugars and added extras lower the protein per 100 g. A "cheap" tub at 60% protein can cost more per gram of protein than a dearer isolate.
FAQ
How do you define best value?
The lowest price per gram of protein, using the protein per 100 g on the label and the best-value size in stock. We do not score taste or mixability because we have not tasted the products.
Does best value include shipping?
No. Shipping depends on your order size and location. Many stores ship free above a threshold, so bundle orders where you can.
