Whey Protein Isolate

Whey Protein Isolate appears in 2,869 indexed US food products. No FDA SAFFA status or CSPI rating is attached in this snapshot, so this page reports prevalence rather than a safety verdict.

What the data can answer

Whey Protein Isolate appears in 2,869 catalogued products, but this snapshot has no FDA SAFFA status or CSPI Chemical Cuisine rating attached to it. This page therefore cannot answer whether the ingredient is safe from those sources. It can show how often it occurs, where it tends to sit on labels, and which kinds of products contain it.

Catalog prevalence comes from Open Food Facts ingredient lists. FDA SAFFA and CSPI Chemical Cuisine labels are shown only when the source record contains them.

What this page can and cannot answer

Separate this ingredient from its product neighborhood

This is a mixed product neighborhood: 1350 of 2869 records have some flagged component, while the rest do not. Compare 100% Gold Standard Whey; 100% Gold Standard Whey Double Rich Chocolate; 100% Mass Gainer Chocolate Fudge Brownie to see how surrounding formulations change; do not assign their 0–100 score range to Whey Protein Isolate itself. The ingredient most often sits near the top of the captured list, and Snacks supplies the most useful like-for-like starting point for a label review.

1350 of 2,869 linked records have some flagged component

All 2869 NOVA-classified records cluster most heavily in Group 4, while the first-category labels split across several shelves. That makes the 0–100 score spread more informative than the average alone: investigate the low end, identify the actual flagged row, and compare it with a similar unflagged formulation before drawing a conclusion.

Next check: pair one flagged product with a similar unflagged product from the same shelf category.

Typical depth in an ingredient list
19%
Of the way down the captured list, averaged across the 2,869 products listing it (mean slot 5.9). Whey Protein Isolate usually falls near the top of the captured list; this position does not measure its amount because source formatting, compound ingredients and labeling exceptions vary.

Computed from parsed product ingredient lists (Open Food Facts). The ranking covers 247,206 ingredients that appear at least once. Neither usage rank nor label depth is a safety clearance.

What else is usually in the same product as Whey Protein Isolate

Across the 2,869 products on this site that list Whey Protein Isolate, these flagged additives appear alongside it most often.
