Product analysis
C4 Original Cherry Limeade may help with resistance to fatigue during intense exercise through beta-alanine taken regularly over several weeks. Its combination blend does not identify the individual ingredients, making the rest of the mix harder to judge.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality40
Niacin has a clearly identified source, but the quality of much of the mix remains uncertain. Several forms are unspecified, and the combination blend does not name its components.
Ingredient Transparency61
Most amounts are listed, but only some ingredient forms are disclosed. The unnamed blend components make it harder to understand the full formula.
Value For Money35
The niacin and folate contributions offer limited value at the full serving price. Arginine alpha-ketoglutarate also looks relatively costly for the amount, while value for most other ingredients remains uncertain.
Customer Satisfaction82
Customer feedback is very positive. Thousands of ratings give a broad picture of satisfaction.
Product Focus34
Beta-alanine gives the clearest support for repeated high-intensity exercise, though the serving supplies only part of the daily amount used for that purpose. The blend leaves the full active mix unclear, and an alertness benefit from caffeine cannot be confirmed.
