Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 2732 of 9117 records have some flagged component, while the rest do not. Compare 100% Whole Wheat Bread; 12 Grain Bread; 12 Slider Potato Rolls (1) to see how surrounding formulations change; do not assign their 0–100 score range to Ferrous Sulfate itself. The ingredient most often sits in the upper half of the list, and Plant-based foods and beverages supplies the most useful like-for-like starting point for a label review.
2732 of 9,117 linked records have some flagged component
All 8895 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.
What else is usually in the same product as Ferrous Sulfate
Across the 9,117 products on this site that list Ferrous Sulfate, these flagged additives appear alongside it most often. The comparison column is how often each one appears across every product with a parsed ingredient list, so the two figures are measured over the same set. Caramel Coloring shows up about 1.6x more often with Ferrous Sulfate than in the catalogue at large.
| Additive | Shared products | Share of Ferrous Sulfate products | Share of all products |
|---|---|---|---|
| Caramel Coloring | 861 | 9.4% | 5.7% |
| Carrageenan | 636 | 7% | 4.5% |
| Yellow 5 | 566 | 6.2% | 4.8% |
| Yellow 6 | 546 | 6% | 3.4% |
