The Bix Big 40 Caffeine Energy Gel delivers 40g of carbohydrates, 200mg of sodium, and 75mg of natural caffeine per gel — significantly more fuel and a meaningful caffeine dose in a single serve. A 1:0.8 glucose-to-fructose ratio uses dual carbohydrate transport pathways for improved absorption at high intensity, alongside a caffeine dose timed for mid-race use. Made in the UK in a GMP-certified facility.

What it delivers

40g carbohydrates per gel — 1:0.8 glucose-to-fructose ratio uses dual transport pathways to support carbohydrate absorption during high-intensity and long-duration efforts

75mg natural caffeine per gel — equivalent to a strong espresso; caffeine contributes to increased alertness and improved concentration

200mg sodium per gel — meaningful electrolyte dose per serve, contributing to the maintenance of normal fluid balance during training and racing

Vegan, natural flavours and colours — no artificial additives

HOW TO USE?

Take 1–2 gels per hour, depending on the duration and intensity of your activity. Stay hydrated throughout your exercise. Do not exceed 3mg of caffeine per kg of body weight per day.

WHEN TO USE?

During training or racing. Best used mid-race or during hard efforts lasting over 60 minutes where both sustained carbohydrate intake and mental focus are critical.

WHY DO I NEED THIS?

The Big 40 Caffeine delivers 40g of dual-source carbohydrates and 75mg of natural caffeine — fewer gels to carry, less maths mid-race, and a clean caffeine boost when you need it most. Combined with 200mg of sodium, it covers energy, electrolytes, and focus in one go.

WHO USES THIS?

Cyclists, runners, triathletes, and endurance athletes who follow a high-carb fuelling strategy and want a caffeine boost during key race moments or hard training sessions.

Customer photo review of Precision Fuel & Hydration Flow Bottle 300

I received a regular drinking bottle, not the Flow bottle with the more flexible plastic and carb markings, which is specifically why I wanted to buy it. I don't want 15% off, I want my money back

Precision Fuel & Hydration Flow Bottle 300

Easy to use and taste good. I normally do 4 scoops in a 500ml bottle and complement with gels and chews
