Least Processed Protein Powder Brands
Protein powders undergo extensive industrial processing to isolate and concentrate protein from milk (whey, casein) or plants (pea, soy). The base protein extraction is inherently industrial, but processing scores increase further with added artificial sweeteners, flavors, thickeners, and fillers like maltodextrin.

How We Score Products
Every product is evaluated using two independent scores. The Processing Score (lower is better) measures the degree of industrial processing based on ingredient analysis, including the presence of artificial additives, preservatives, and highly modified ingredients. The Nutrition Score (higher is better) rates overall nutritional quality, rewarding protein and fiber while penalizing excess sodium, added sugars, and saturated fat.
Products are assigned to one of four processing levels: Minimal (score ≤ 2.5), Processed (2.6 – 5.0), Highly Processed (5.1 – 8.0), and Ultra-Processed (above 8.0). Brand averages are calculated across all products in the category to produce the rankings shown here.
Based on analysis of 1.98 million products in the USDA FoodData Central database. For a deeper look at the methodology, see our Processing Score guide and Two-Score System explanation.
Frequently Asked Questions
Is protein powder ultra-processed?
All protein powders are at least Level 3 because protein isolation is an industrial process. Unflavored powders with minimal additives score lowest; flavored varieties with sweeteners and fillers reach Level 4.
Which protein powder is least processed?
Unflavored whey protein isolate or concentrate with 1-3 ingredients scores lowest. The brands ranked here have the most minimal formulations across their product lines.
Is plant protein powder more processed?
Plant protein isolation (from peas, soy, rice) requires more processing steps than whey extraction from milk, but the final additive load matters more for scoring.
