Solid on the numbers
Scored on the label and the price, not on how it tastes. How we score.
How the numbers stack up against the price
39p buys 25g of protein here, which makes it the 1st cheapest of the 18 powders we have reviewed, and 47p under the median.
If you want plant protein without a blend, a vitamin premix or a marketing tier attached, this is the honest version of that. What you give up is leanness: pea protein carries its own fat, so this runs 396 kcal and 5.1g of fat per 100g, the highest calorie figure in the range and roughly four times the fat of the vegan blends. Pea alone is also lower in methionine than a soy or pea-and-rice blend, which matters if it is your only protein source rather than one of several.

Cheapest in-stock listing at a partner retailer, for packs of 400g and over. NXT Nutrition Beef Protein Isolate has no partner listing in stock, so it carries no figure.
A single-source pea protein isolate, and the ingredient list is six items long: pea protein isolate, flavouring, salt, colour, thickeners and sucralose. No vitamin blend, no enzymes, no second protein. That simplicity is the product.

Where to buy it
Ordered by cost per 25g of protein, because pack sizes and protein densities differ enough that a headline price on its own does not tell you which is better value.

Questions buyers ask
The things people search for about Protein Works Vegan Pea Protein - BLACK Innovation, answered from the label and the live partner prices rather than from the brand’s own copy.
Is Protein Works Vegan Pea Protein good value?
It is the cheapest protein they sell, at about 39p per 25g of protein on the 4kg bag, and one of the cheapest we track from any brand. The trade-off is 396 kcal and 5.1g of fat per 100g.
Is pea protein as good as whey?
Per gram of protein it is close on most measures but lower in methionine, and pea isolate carries more fat than whey isolate does. As one protein source among several in a day the difference is small. As your only one, a multi-source plant blend covers the amino acid profile better.
Does Protein Works Vegan Pea Protein contain soy?
No. Pea protein isolate is the only protein source, which makes this the soy-free option in their vegan line.
