GU Energy Original Sports Nutrition Energy Gel Salted Caramel

In this review the GU Energy Original Sports Nutrition Energy Gel in Salted Caramel is evaluated for endurance athletes who need quick, portable calories and electrolytes during long efforts. The bottom line: this gel delivers a compact 100-calorie boost with both fast-absorbing carbohydrates and added electrolytes, making it a reliable mid-workout pick for runners, cyclists, and hikers who want steady energy without heavy stomach issues.

Key Features

• Dual-source energy: The blend of maltodextrin and fructose supplies energy through non-competing pathways for efficient absorption and steadier fuel during long activities.
• Portable 100 calories: Each single-serve packet packs 100 calories in a lightweight packet that is easy to stash in a pocket or jersey for training or racing.
• Electrolyte support: With 125mg sodium and 40mg potassium per packet, it helps maintain water balance and reduces cramping risk during extended exercise.
• Branched-chain amino acids: BCAAs are included to help limit muscle fiber damage and support faster recovery after intense sessions.
• Caffeinated option: The Salted Caramel flavor contains 20mg caffeine to boost concentration and alertness during late-stage efforts.

Who It's For

The GU Original Salted Caramel gel is best for endurance athletes doing continuous efforts - long runs, cycling centuries, multi-hour hikes, or ski tours - who need reliable, calorie-dense fuel that is easy on the stomach. Its portable packets and guidance to take one 5 minutes before and every 45 minutes during activity make it convenient for both training and race day.

Athletes seeking entirely stimulant-free options or those who need much higher sodium per serving for extreme heat may prefer alternate formulations, but most recreational and competitive endurance athletes will find the electrolyte and carbohydrate balance appropriate.

Pros & Cons

Pros

• Provides quick, sustained energy from a dual carbohydrate blend that absorbs efficiently.
• Added electrolytes and BCAAs support hydration and recovery during long workouts.
• Salted Caramel flavor is not overly sweet and includes a mild caffeine boost for focus.

Cons

• One packet supplies only 20mg caffeine, so those needing a larger stimulant effect must combine with other sources or choose a different flavor.
