Plant-Based Protein Powder Compared
Plant-based protein has come a long way. Modern vegan blends combine pea, rice, hemp and soy isolates to deliver complete amino acid profiles that rival whey — often at a lower price point.
This page shows every plant-based protein powder we track across UK retailers, ranked by cost per 25g of protein. Whether you are fully vegan, lactose intolerant, or just looking for a lighter alternative to whey, you can compare options side by side on price, protein content and macros.
All prices are checked weekly. Use the filters to narrow by brand, bag size or specific plant protein type.
Frequently Asked Questions
Is plant-based protein powder as good as whey?
For muscle building, plant-based protein can be just as effective as whey when you choose a blend with a complete amino acid profile. Pea and rice protein together provide all essential amino acids. The main trade-off is taste and texture — plant proteins tend to be grittier and more earthy than whey.
Which plant protein has the most protein per 100g?
Soy protein isolate and pea protein isolate typically deliver 80-85g of protein per 100g, which is comparable to whey concentrate. Blended plant proteins (pea + rice + hemp) usually sit around 70-75g per 100g due to the mix of sources.
Is vegan protein powder cheaper than whey?
Generally yes. Plant-based protein powders tend to be cheaper per gram of protein than whey, partly because the raw ingredients cost less. However, premium vegan brands can match or exceed whey prices. Use this comparison table to find the best value option.
