L-arginine
L-arginine carries a source-backed screening score of 3/5 and appears in 69 indexed US food products.
Source-backed answer
L-arginine appears in 69 catalogued products. CSPI has no rating attached in this snapshot. Its FDA SAFFA status is “Approved.” Those source labels describe the ingredient; they do not establish whether a particular product, dose, allergy, or diet is safe.

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.
L-arginine sits in the busiest tenth of the catalog (#4,011 / 247,206)
- Usage rank
- #4,011
- of 247,206 ingredients that appear in at least one catalogued product, tied with 35 others that also appear in exactly 69 products, listed in more products than 98.4% of them.
- Typical depth in an ingredient list
- 36%
- Mean relative depth 36% across 69 parsed labels, slot 14.0 on average. L-arginine tends to sit in the upper half of the list. Depth is location on the label, not a measured dose.
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.
Reading this ingredient record
Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 30 of 69 records have some flagged component, while the rest do not. Compare Abbott, Juven, Tissue Building Powder, Orange, Orange; AMINOLEAN ENERGY; AminoLean Pre-Workout to see how surrounding formulations change; do not assign their 70–100 score range to L-arginine itself. The ingredient most often sits in the upper half of the list, and Beverages supplies the most useful like-for-like starting point for a label review.
30 of 69 linked records have some flagged component
All 65 NOVA-classified records cluster most heavily in Group 4, while the first-category labels split across several shelves. That makes the 70–100 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 L-arginine
Across the 69 products on this site that list L-arginine, 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. Sucralose shows up about 13.4x more often with L-arginine than in the catalogue at large.
| Additive | Shared products | Share of L-arginine products | Share of all products |
|---|---|---|---|
| Sucralose | 25 | 36.2% | 2.7% |
| Acesulfame Potassium | 12 | 17.4% | 1.8% |
| Carrageenan | 8 | 11.6% | 4.5% |
