Tryptophan
Tryptophan appears in 14 indexed US food products. No FDA SAFFA status or CSPI rating is attached in this snapshot, so this page reports prevalence rather than a safety verdict.
What the data can answer
Tryptophan appears in 14 catalogued products, but this snapshot has no FDA SAFFA status or CSPI Chemical Cuisine rating attached to it. This page therefore cannot answer whether the ingredient is safe from those sources. It can show how often it occurs, where it tends to sit on labels, and which kinds of products contain it.

Reading this ingredient record
Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 3 of 14 records have some flagged component, while the rest do not. Compare Collagen Peptides; Fresh Banana; Frog Fuel Power Protein to see how surrounding formulations change; do not assign their 85–100 score range to Tryptophan 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.
3 of 14 linked records have some flagged component
All 13 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.

- Of the way down the captured list, averaged across the 14 products listing it (mean slot 11.2). Tryptophan usually falls in the lower half of the list; this position does not measure its amount because source formatting, compound ingredients and labeling exceptions vary.
Ranks use Open Food Facts ingredient rows on this site’s refresh cycle. 247,206 ingredients with ≥1 product appearance enter the ranking. Prevalence and list depth are catalog facts, not toxicology.
How do the sampled products compare?
Each point is one of the 14 sampled products listed below: its overall safety score against how many separately flagged ingredients its label carries. Bubble size is the number of ingredient rows the label actually resolved to.
