If you’re gearing up for a tough training session, race, or anything that demands focus and energy, the STYRKR GEL30 Caffeine Dual-Carb Energy Gel is a solid choice.

Each gel delivers 30g of carbohydrates and 150mg of caffeine, which provides the energy you need to keep your body performing and the mental clarity to stay sharp. The combination of maltodextrin and fructose gives you a fast, steady release of energy, while the caffeine works to enhance focus and delay fatigue.

It’s isotonic, meaning you don’t need to drink extra water to help with absorption, which is great during those times when you’re on the move or don’t want to slow down. Plus, the 150mg of caffeine is a perfect amount to give you a boost without feeling jittery, which is especially helpful if you’re tackling a long run or an intense cycling session.

Who it’s for:

Athletes needing fast fuel plus mental clarity – perfect for hard sessions, hill intervals, races, or just for when fatigue hits hard.

What it does:

Delivers 30g of dual transportable carbs for fast spike-and-sustained energy plus 150mg caffeine to sharpen focus, reduce perceived effort, and support endurance under fatigue.

How I would use it:

Take one gel 10–15 minutes before starting or one every 45–60 minutes during prolonged or high-intensity activity. Sip water to aid absorption and avoid stomach upset.

The Science:

Carbohydrate–Caffeine Co‑ingestion Enhances Endurance Performance Compared to Carbohydrate Alone

Study: Controlled trial in trained cyclists comparing performance outcomes of carb-only vs carb+caffeine intake during prolonged exercise.

European Journal of Applied Physiology (Jeukendrup review) (2021)

https://pubmed.ncbi.nlm.nih.gov/34229454/

Adding 3-6mg/kg caffeine to carbohydrate intake improved time‑trial performance, increased alertness, and lowered perceived exertion – even with moderate carb loads. Equates well to GEL30’s 150mg caffeine plus 30g carbs for performance boost.

Dual-Transportable Carbohydrate Feeding (Glucose + Fructose) Increases Exogenous Carbohydrate Oxidation and Reduces GI Distress

Study: Crossover trial comparing glucose-only vs glucose+fructose ingestion on oxidation rates and GI tolerance during prolonged cycling.

Sports Medicine meta-analysis (2018)

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6110277/

Blends of glucose + fructose supported higher carbohydrate oxidation (up to 1.5 g/min) and better GI tolerance than single-carbohydrate sources. GEL30’s 1:0.8 dual-carb system mirrors this evidence-backed ratio for sustained absorption and fewer gut issues.
