Complete Whey Isolate Matrix: All 51 Products Compared (2026)

All 51 whey isolates in our catalog, side by side. Isolates run 90%+ protein content with lactose stripped out, making them the go-to choice for lactose-sensitive lifters and anyone cutting strictly on protein and water. This matrix shows the Value Score, macros, and price floor for every isolate we track so you can pick the right one for your wallet and your stomach.

How to Read This Matrix

Twelve columns, one row per product. The columns are: rank by Value Score, brand (links to the brand page), product name (links to the full live-price page), flavor, tub size in pounds, grams of protein per serving, total servings in the tub, calories per serving, cheapest in-stock price across our 12 tracked US retailers, the retailer at that price, the Value Score (0-100, higher is better), and short notes calling out the most relevant detail like grass-fed, hydrolyzed, or organic.

Why whey isolate matters

Isolate is filtered further than concentrate. The result is more protein per scoop (typically 25-30g vs 20-24g for concentrate), almost no lactose, and a higher price tag. The matrix below lets you spot the value plays: a few brands have closed the gap to concentrate prices while keeping the macro profile premium.

The single Value Score column is the right place to start, but it is not the only way to slice this matrix. Here are five different angles on the same product set:

How We Built This Matrix

Every row above is generated directly from our live product catalog. When the scraper checks each retailer (every two hours throughout the day), the cheapest in-stock price wins the right-hand column. Value Score is recalculated whenever a price changes. We do not score products that are out of stock at every retailer.
