Authentic Nutrition's Flapjack
Highly appreciated by athletes for its progressive carbohydrate release, the Flapjack is a very energetic British cake, primarily made from rolled oats.

The usefulness of energy bars for sports
Energy bars for sports are designed to provide a quick, balanced nutritional intake and support athletes' endurance and performance. They are particularly useful for:
• Maintaining energy: thanks to their content of oats, which are soluble fibers, or complex carbohydrates, they release energy gradually, thus preventing fatigue.
• Ease of transport: compact, divisible, and easy to carry, they are perfect for long training sessions, competitions, or even hikes.
• Nutritional support: enriched with proteins, soluble fibers, and micronutrients, they contribute to muscle recovery and satiety.
Did you know? In addition to energy bars, energy gel, composed of glucose and fructose, offers a rapid intake of easily assimilated carbohydrates. Its texture allows you to recharge your batteries without having to slow down! It is thus perfect for intense or prolonged efforts. The energy chew, which is easy to chew or melt, releases energy more gradually.

Which sports bar to eat during exercise?
An optimal energy bar should contain healthy ingredients and high nutritional quality. Guaranteed gluten-free, our flapjack bars are primarily composed of rolled oats, known for their many nutritional benefits: complex carbohydrates, soluble dietary fiber, and protein.
Indeed, rolled oats provide sustained energy release, and the fiber present in oats promotes digestion while contributing to a lasting feeling of satiety.
To be totally effective, sports bars must also contain essential vitamins and minerals such as:
• B vitamins: important for energy metabolism.
• Magnesium: essential for muscle function and cramp prevention.
• Antioxidants: to combat oxidative stress and promote recovery.

When to consume an energy bar for optimal effect?
You have an energy bar on hand, but you're unsure of the ideal time to consume it? Each phase addresses specific needs, discover how to get the most out of your bar to optimize your athletic performance!
Before exercise
Consuming an energy bar about an hour before physical activity can help maximize your glycogen stores and prepare your body for the upcoming effort. The complex carbohydrates in rolled oats ensure a gradual release of energy, ideal for starting strong. Our flapjack bars can also be consumed for breakfast, ideally with 100g of bananas, 30g of almonds, and sparkling water.
Before a long effort, another valuable ally will be: the maltodextrin-based drink. Rich in slow-release carbohydrates and easy to digest, it helps replenish your energy reserves without overloading your stomach. It will also help you limit fatigue from the start of your effort.
During exercise
For long-duration endurance activities (more than 90 minutes), a ~25 gram bite every half hour can be consumed to maintain stable energy levels and prevent hunger pangs while remaining focused. Our bars are easy to digest, so they won't weigh down your stomach during your effort. This is a major asset for your long outings or competitions.
After exercise
Within 30 minutes after exercise, consuming an energy bar helps replenish glycogen stores and promote muscle recovery. Rich in carbohydrates, it will be the perfect support for your muscle recovery. It is also an ideal snack to avoid post-workout cravings, even if it is generally advisable to eat a high-protein bar specifically dedicated to recovery. Combined with good hydration, it will help you accelerate recovery and limit fatigue.
