Product analysis
C4 Original Icy Blue Razz includes beta-alanine, which may help with fatigue during intense exercise when used regularly over several weeks. The undisclosed blend contents make the complete formula harder to assess.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality40
Niacin is clearly identified, but the quality of many other ingredients remains uncertain. Several missing forms and unidentified blend components limit a fuller comparison.
Ingredient Transparency61
Most ingredient amounts and some forms are disclosed. The blend contents remain unidentified, so a total blend amount cannot show what each component contributes.
Value For Money35
The serving cost offers weak value for niacin and folate, with limited value from arginine alpha ketoglutarate. The value of most other ingredients remains uncertain.
Customer Satisfaction88
Customer feedback is positive across a large review base. The volume strengthens confidence in satisfaction without confirming workout benefits.
Product Focus34
Beta-alanine provides the clearest connection to intense-exercise endurance. A serving supplies less than the daily amounts used for that purpose, while caffeine content and the effects of the creatine preparation remain uncertain.
