When you need sustained energy that tastes good, Science in Sport (SiS) delivers with their first-ever Energy Oat Bar. This isn’t just another energy bar – it’s SiS bringing over three decades of sports nutrition science to your training routine.

Real Energy, Real Food

Packed with 40 g of carbohydrates and 10 g of protein, this bar bridges the gap between performance nutrition and real food satisfaction. Made with natural ingredients, it delivers fuel without the artificial aftertaste that makes you cringe mid-workout.

Two Flavors That  Work

Choose your fighter: White Chocolate & Macadamia for an indulgent energy boost, or vegan-friendly Blueberry for plant-based athletes who refuse to compromise on taste or performance.

The Science Behind Your Fuel

SiS has spent three decades using scientific research to create products that work. This bar strikes the perfect balance of carbs, protein and fiber to support both elite performance and your Tuesday morning training session.

How to Use It:

Perfect as a pre-workout boost, mid-session fuel, or post-training recovery snack. The oat base provides sustained energy release while protein supports muscle recovery – making it versatile for whatever your training throws at you.
