The verdict

C4 Ultimate by Cellucor scores 70/100 in PlainFoodSafe's ingredient screening. We compared its 44 labeled ingredients with FDA SAFFA regulatory records and CSPI Chemical Cuisine ratings; 2 ingredients are flagged for caution. The source parser split this into a very long 44-component record, beginning with Vitamin B6, As Pyridoxal-5-phosphate, Folate. That density can include amounts and label fragments, so verify the physical label before relying on ingredient order or completeness. This is not a recall, allergy, medical, or dietary-safety determination.

What the Data Says About C4 Ultimate

C4 Ultimate by Cellucor carries a composite safety score of 70/100, which we classify as "Caution" on our four-tier shelf-label framework.

Of the 44 ingredients parsed from this label, 8 are covered by a regulator or watchdog we screen against (L-arginine, L-tyrosine, Calcium Silicate and 5 others), with 8 carrying an FDA Substances Added to Food (SAFFA) status and 5 a CSPI Chemical Cuisine rating. The remaining 36 ingredients appear in neither registry, so they neither raise nor lower the score. Each additive rated caution-or-worse penalizes the composite. 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 identified 2 flagged ingredients in this product, components that at least one official source has classified as requiring caution, targeted avoidance, or further evaluation. Flagged ingredients are the items most likely to surface in FDA inspection findings, state-level ingredient bans, or outbreak-related recall notices, so the per-ingredient breakdown below is the most useful lens for anyone screening this product for a specific dietary concern.

On the NOVA processing scale, C4 Ultimate 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.
