How to use this page
Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 4 of 11 records have some flagged component, while the rest do not. Compare EleCare Infant Formula; Essential Skin Food; Gummy choco to see how surrounding formulations change; do not assign their 85–100 score range to L-proline itself. The ingredient most often sits in the lower half of the list, and Dietary supplements supplies the most useful like-for-like starting point for a label review.
4 of 11 linked records have some flagged component
All 11 NOVA-classified records cluster most heavily in Group 4, while the first-category labels split across several shelves. That makes the 85–100 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.
