The question of how much caffeine is in gu gel is not a simple one, as the answer depends on the specific type of GU gel and its flavor. GU Energy offers several gel categories—Original, Roctane, and Liquid—each with its own range of caffeine levels to suit different performance needs during training and competition.
GU Original Energy Gels
The Original GU Energy Gels offer a diverse palette of flavors, with caffeine content split into three distinct tiers: caffeine-free, moderate caffeine, and high caffeine.
Caffeine-Free Options
For athletes sensitive to stimulants or those training in the evening, several flavors provide fuel without any caffeine. These include:
- Strawberry Banana
- Birthday Cake
- Campfire S'mores
- Pumpkin Spice
- Lemon Sublime
- Raspberry Lemonade
Moderate Caffeine (20mg)
These flavors provide a mild boost of 20mg of caffeine per packet, which is less than a quarter of the amount in an average cup of coffee. This level is suitable for those who want a gentle uplift during a workout without the intensity of a larger dose. Options with 20mg include:
- Chocolate Outrage
- Mandarin Orange
- Vanilla Bean
- Triberry
- Tastefully Nude
- Chocolate Peanut Butter
- Salted Watermelon
- Mint Chocolate (may vary, check label)
High Caffeine (40mg)
Offering a more significant 40mg of caffeine per serving, these flavors are designed for a more pronounced mental and performance boost. Athletes often use these strategically during the later stages of a long race. Flavors with 40mg include:
- Caramel Macchiato
- Espresso Love
- Jet Blackberry
- Cola Me-Happy
GU Roctane Ultra Endurance Gels
Designed for longer duration and higher-intensity exercise, Roctane gels contain more electrolytes and amino acids than the original formula. The caffeine content also differs, with some flavors containing a higher dosage.
Caffeine-Free Roctane
- Pineapple
- Strawberry Kiwi
Moderate Caffeine (35mg)
Most caffeinated Roctane gels contain 35mg of caffeine per serving, offering a strong boost for demanding activities.
- Blueberry Pomegranate
- Chocolate Coconut
- Vanilla Orange
- Cherry Lime
- Sea Salt Chocolate
- Salted Lime
- Tutti Frutti (may vary, check label)
- Chai Latte (may vary, check label)
High Caffeine Roctane (70mg)
- Cold Brew Coffee contains a robust 70mg of caffeine per gel, making it the most potent option in the GU lineup.
GU Liquid Energy Gels
For those who prefer a thinner, more liquid consistency, GU offers Liquid Energy Gels. The caffeine content for this product line is similar to the Original gels but varies by flavor.
Caffeine-Free Liquid Energy
- Strawberry Banana
- Lemonade
Caffeinated Liquid Energy
- Orange: 20mg caffeine per packet.
- Coffee flavors: 40mg caffeine per packet.
Choosing Your Caffeine Strategy
Selecting the right caffeine level is a personal choice based on your tolerance, workout length, and goals. Caffeine can sharpen focus, decrease the perception of effort, and aid performance during endurance activities. However, excessive intake can lead to jitters, increased heart rate, and disrupted sleep.
During long events, many athletes alternate between caffeinated and non-caffeinated gels to manage their intake and avoid overstimulation. For example, using a caffeine-free gel for the first hour of a run and then switching to a caffeinated flavor during the middle or later stages can provide a well-timed boost. Always experiment with your fueling strategy during training to find what works best for your body.

The Difference Between GU Original, Roctane, and Liquid Gels
The key difference lies in their formulation. Original gels are a balanced fuel for daily training. Roctane gels are designed for high-intensity, long-duration efforts with more sodium, amino acids, and often higher caffeine. Liquid gels offer the same nutrition in a lighter, more drinkable consistency.
Tips for Using Gels and Avoiding Side Effects
- Stay hydrated: Always consume gels with water to aid absorption and prevent digestive issues.
- Train your gut: Practice your fueling strategy during training runs or rides, not just on race day.
- Introduce gradually: If you are new to caffeinated gels, start with a lower dose to assess your tolerance.
- Mind your timing: Use caffeinated gels strategically, especially in the latter half of a long event, and avoid consuming them too close to bedtime.
