What to know
Getting complete protein without animal sources
Individual plant proteins like pea or rice are often lower in one or two essential amino acids on their own. Manufacturers get around this by blending two or more plant proteins together, and research comparing whey to well-formulated plant protein blends has found no meaningful difference in how well they support muscle in adults, according to Mayo Clinic Press.
That means the ingredient list matters more than the word vegan on the front of the package. A bar built on a single, thin plant protein source is a different product than one built on a blended pea, rice, or soy protein formulated to cover the full amino acid profile.
We score every vegan bar the same way as every other bar on taste, texture, macros, and ingredients, and we note which plant proteins each one uses.
What to check before you buy
- Look for blended proteins, such as pea plus rice or pea plus soy, rather than a single plant protein source, since blending tends to fill in amino acid gaps.
- Vegan does not automatically mean allergen-friendly. Many plant protein bars still use soy, and some use nuts for flavor and crunch, so check the allergen statement even on a vegan bar.
- Plant proteins can have a stronger aftertaste than whey. That is part of what our taste score is measuring, not something you need to guess at.
