At a glance
Summary
This plant-based protein powder includes beneficial ingredients like pea protein, which is a sustainable and allergen-friendly protein source. However, the presence of sucralose, an artificial sweetener, and natural flavors, which lack transparency, detracts from its overall healthiness. The product also contains multiple thickeners, which contribute to its moderate processing level.
