What the Data Says About Gas-X
Gas-X carries a composite safety score of 100/100, which we classify as "Safe" on our four-tier shelf-label framework.
The score is computed by mapping each labeled ingredient against FDA Substances Added to Food (SAFFA) regulatory status and CSPI Chemical Cuisine classifications, then penalizing the overall product for each additive rated as caution-or-worse. Product data originates from the OpenFoodFacts collaborative catalog; safety annotations come from federal regulators and the Center for Science in the Public Interest. This score is a transparent derived index we compute from that public data, not an official FDA rating or endorsement; see the Methodology page for the exact weighting.
Our scan did not identify any ingredients in this product that FDA SAFFA or CSPI Chemical Cuisine data flags as requiring caution or avoidance at the time of analysis. That is a meaningful clean-label signal, though it does not account for personal allergens, regional recalls, or inspection findings not reflected in federal additive databases. The per-ingredient breakdown below shows the source-level classification for each component.
On the NOVA processing scale, Gas-X is classified as Group 4 (Ultra-processed). NOVA measures industrial processing intensity rather than ingredient-level safety, so it complements the SAFFA and CSPI ratings: a product can be clean on additive flags but heavily processed, or lightly processed but carry individually flagged ingredients. Combining both lenses gives a fuller picture than either alone.
