Description

Created with real food ingredients and a carefully balanced nutrient profile, these bars are ideal for endurance athletes, active individuals, and anyone needing a clean, reliable energy boost.

Each bar features a 4:1 carbohydrate-to-protein ratio, a proven formula that supports sustained energy release and aids in muscle recovery. Ingredients like gluten-free oats, honey, peanuts, coconut, and flaxseed meal combine to deliver both quick and lasting fuel, keeping your energy levels steady and your body nourished. Designed for performance but suitable for everyday snacking, these bars are free from gluten, dairy, GMOs, and artificial preservatives.

Bonk Breaker Energy Bars are trusted by elite athletes for their digestibility, clean ingredient list, and excellent taste. With a soft, chewy texture, they’re easy to consume mid-run, ride, or workout—when it matters most. Flavours like Peanut Butter & Jelly not only satisfy your taste buds but also make refuelling feel like a treat, not a chore.

Whether used before a session, during a race, or as a quick snack to bridge meals, Bonk Breaker bars provide smart nutrition in a convenient format. No frills, no junk—just energy you can trust.

How does it work

Bonk Breaker Energy Bars use a smart blend of complex and simple carbohydrates to provide balanced energy. The gluten-free oats and honey offer gradual glucose release, maintaining stable blood sugar and glycogen levels. Added protein and healthy fats from sources like peanuts and flaxseed meal help to slow digestion slightly, ensuring longer-lasting energy and better satiety. The 4:1 carb-to-protein ratio is tailored for endurance, making these bars an ideal option for sustained physical performance.

By focusing on natural, minimally processed ingredients, Bonk Breaker bars also reduce the likelihood of digestive distress, a common issue during endurance events. This makes them especially effective and easy to consume on the go, without sacrificing quality or comfort.

About Bonk Breaker

The name Bonk Breaker comes from a simple philosophy: A well-fueled athlete is less likely to hit the wall (or “bonk”), and great-tasting nutrition is key to eating enough. If you’re going to pummel your body day-in and day-out, you may as well pummel your taste buds with something you enjoy.

“Suffernot the sufferfest,” as we like to say.

We stick to gluten-free, real food ingredients and throwback flavors like Cookies and Cream, Apple Pie, or PB&J. NO dryness, blandness, or messiness – guaranteed.
