What this page can and cannot answer

Separate this ingredient from its product neighborhood

This is a mixed product neighborhood: 101 of 307 records have some flagged component, while the rest do not. Compare 10 Grain Bread Mix; All Natural Chicken Patties; Artisan Sourdough Bread to see how surrounding formulations change; do not assign their 0–100 score range to Magnesium Carbonate itself. The ingredient most often sits in the lower half of the list, and Beverages supplies the most useful like-for-like starting point for a label review.

101 of 307 linked records have some flagged component

All 299 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 Magnesium Carbonate

Across the 307 products on this site that list Magnesium Carbonate, 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. Carrageenan shows up about 2.5x more often with Magnesium Carbonate than in the catalogue at large.
