Is Isopure a good brand?
Isopure is the right choice if you need protein that mixes clear in water with zero carbs, zero fat and zero lactose.

Useful if you're cutting hard, prepping for a stage, or you find traditional milky shakes too heavy. Stocked in Holland and Barrett, Boots, Sainsbury's, Ocado and Amazon UK. WheyWise tracks 1 Isopure products. The cheapest is £2.43 per 25g of protein on Whey Protein Isolate 435g, ranging up to £2.43. Isopure pricing varies more between retailers than most established brands.

Methodology
How we rank every bag.
Independent and transparent. Every price is read from the retailer's own page and checked daily. Here's what goes into each score.
01
Cost normalised to £/25g
Every bag divided by its true protein weight, so you see the real cost of a scoop across any size or brand.
02
Protein density, measured
Protein per 100g from the product's own nutrition panel, so a 90% isolate and a 72% concentrate are never compared on bag price alone.
03
Real prices, checked daily
Prices come from the retailer's own listing, never an RRP, and we re-check them every day rather than leaving a feed to drift.
04
Rankings can't be bought
Rank order is cost per 25g of protein. Some outbound links earn commission, and some Amazon links marked Ad pay per click; none of them buy a position in the table.
