What this page can and cannot answer
Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 16 of 45 records have some flagged component, while the rest do not. Compare ACTIVE Essential Amino Acid Blend; Amino K.e.m.; AMINO+ EAA/BCAA Strawberry Kiwi to see how surrounding formulations change; do not assign their 70–100 score range to L-histidine itself. The ingredient most often sits in the upper half of the list, and Dietary supplements supplies the most useful like-for-like starting point for a label review.
16 of 45 linked records have some flagged component
All 45 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-histidine
Across the 45 products on this site that list L-histidine, 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 12.3x more often with L-histidine than in the catalogue at large.
| Additive | Shared products | Share of L-histidine products | Share of all products |
|---|---|---|---|
| Sucralose | 15 | 33.3% | 2.7% |
| Acesulfame Potassium | 5 | 11.1% | 1.8% |
