Please see specific promotion Terms & Conditions for details BFPO Addresses We do ship to BFPO addresses (with Royal Mail) but for active combat zones there is a strict 2kg weight limit (as with all deliveries to BFPO addresses), so please take this into account when ordering. As a guide, with careful packaging we can just get away with a 1.6kg tub. All orders under this weight limit will be treated as standard UK orders.

REAL INGREDIENTS. REAL ENERGY.

FORMULATED BY SCIENCE

Carbohydrates and protein work together to restore energy, repair muscle, and support endurance. Each bar provides a balanced 40g of carbs and 10g of protein, helping you meet your performance and recovery goals with ease.

 

BALANCED ENERGY

Both nutrients are essential for athletes: carbs replenish glycogen for energy, while protein aids muscle repair and adaptation. Current sports nutrition research recommends 3–12g of carbs per kilogram and at least 1.6g of protein per kilogram daily for active individuals.

BALANCED ENERGY

Carbohydrates and protein are both essential nutrients for athletes because they support energy production, recovery, muscle growth, and overall performance (1,2). Each Energy Oat Bar delivers 40g of carbohydrates to support important carbohydrate loading before exercise or competition, helping to optimize muscle glycogen stores. The 10g of added protein helps meet your daily needs and supports recovery.
Current sports nutrition guidelines show that athletes need between 1.4–5.4 g of carbohydrates per pound of body weight per day, depending on their training and competition schedule (3). The Energy Oat Bar provides 40g of carbohydrates per serving, making it a practical way to boost your daily intake between meals. It also provides 10g of protein, helping endurance athletes reach their recommended daily intake of at least 0.7 g of protein per pound of body weight. The Energy Oat Bar can also be enjoyed during long, low- to moderate-intensity training sessions and is ideal for fueling breaks or coffee stops during long rides.

1. Carbohydrates contribute to the recovery of normal muscle function (contraction) after highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle. The beneficial effect is obtained with the consumption of carbohydrates, from all sources, at a total intake of 4 g per kg body weight, at doses, within the first 4 hours and no later than 6 hours, following highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle.

2. Protein contributes to the growth & maintenance of muscle mass.
