Analysis

The formula combines 100 mg of caffeine with 5 grams of amino acids to support both mental and physical stamina. I find it helpful that it includes electrolytes like magnesium and sodium, as even mild dehydration can drain your energy and focus.

This version is slightly more affordable per serving than some competitors, making it a good daily option for productivity. It supports weight loss efforts by providing an energy boost for workouts without adding significant calories.

Pros

  • Good value at $0.66 per serving
  • Provides 100 mg of caffeine for a controlled energy boost
  • Contains electrolytes for better hydration
  • Low-calorie alternative to sugary soda or energy drinks

Cons

  • Proprietary amino blend lacks transparency
  • Contains artificial ingredients and colors
  • Green coffee and tea extracts are not standardized

Warnings

  • Monitor your heart rate if taking this before heavy exercise
  • Avoid using if you are sensitive to artificial sweeteners
  • Check total daily caffeine intake to avoid sleep disruption
