Product analysis
C4 Original Fruit Punch includes beta-alanine, which may support resistance to fatigue during intense exercise with repeated use. Its unnamed blend makes the full contents harder to judge.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality42
Niacin is clearly identified, but quality remains uncertain for much of the formula. Folate and the combination blend have no specified preparation, and the blend lacks named components.
Ingredient Transparency63
Most listed amounts and several ingredient forms are disclosed. The unnamed blend and some unspecified preparations prevent a complete view of the contents.
Value For Money35
Value is weak for niacin and folate and limited for the arginine ingredient at the full serving cost. Value remains uncertain for several of the workout ingredients and other nutrients.
Customer Satisfaction88
Customer ratings are favorable. The review count provides an extensive base of feedback, without confirming health benefits.
Product Focus34
Beta-alanine has a narrow role in resistance to fatigue during intense exercise after repeated use over weeks. The blend’s unnamed components leave its additional energy or alertness contribution unclear.
