Product analysis
Prolific Sour Green Apple may help with short-term alertness and exercise performance, with caffeine providing its clearest benefit. Missing ingredient details make the wider formula harder to compare with alternatives.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality28
Several ingredients have unspecified forms, limiting confidence in their particular quality. Naming caffeine, citicoline and coffee fruit extract makes those ingredients easier to identify but does not establish better results.
Ingredient Transparency61
All active ingredient amounts are stated, so serving sizes can be compared. Several forms and the proportions of the caffeine mixture are missing, leaving part of the formula unclear.
Value For Money35
The small amounts of theanine and rhodiola offer weak value relative to the full serving price. Value for several other ingredients remains uncertain, so the formula has no clear price advantage.
Customer Satisfaction71
Buyers generally give favorable ratings. The relatively small review pool offers a more limited picture of customer satisfaction.
Product Focus64
Short-term alertness and exercise performance are the clearest uses for this broad formula. Support for muscle gain, weight loss and lasting cognitive benefits is more limited.
