Why do some vegan protein shakes have a chalky texture or distinct taste?
Vegan protein shakes rely on plant-derived proteins like pea, soy, or hemp. These proteins have different solubility profiles and larger particle sizes than dairy-based whey, which can create a grittier or chalkier mouthfeel. Additionally, formulations designed to maximize protein yield while minimizing sugars often rely on stevia or monk fruit, which can alter the flavor profile.
