What this page can and cannot answer
Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 48 of 184 records have some flagged component, while the rest do not. Compare 1,000mg Vitamin C Pink Lemonade; 100% Grass Fed Bone Broth Protein Pure Unflavored; ADVANCED MAGNESIUM+ POWDER to see how surrounding formulations change; do not assign their 30–100 score range to Glycine itself. The ingredient most often sits in the lower half of the list, and Plant-based foods and beverages supplies the most useful like-for-like starting point for a label review.
48 of 184 linked records have some flagged component
All 184 NOVA-classified records cluster most heavily in Group 4, while the first-category labels split across several shelves. That makes the 30–100 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 Glycine
Across the 184 products on this site that list Glycine, these flagged additives appear alongside it most often.
