What to look for
- Protein per 100 g: plain pea and soy isolates are typically 75–85%; flavoured blends 60–75%.
- Blends vs single source: brands blend pea with rice or fava for taste and amino acid balance. Both are fine; compare on price per kg of protein.
- Allergens: soy and peanut are common allergens; check the label.
FAQ
Is plant protein cheaper than whey?
Sometimes. Single-source isolates (pea, soy, rice) can be as cheap as whey per kg of protein; flavoured blends are usually dearer. Compare with our whey ranking.
Are all plant proteins vegan?
Most are, but check the label and the brand: some add honey or vitamin D3 from lanolin, and some are made in facilities that also handle dairy.
