Product Description

Coated in smooth, rich chocolate, these bars offer an indulgent experience without compromising on your nutritional goals. Whether you're tackling a long day of training, recovering from a tough workout, or need a protein boost between meals, this bar is designed to meet your needs.

This bar is not just about protein; it’s a well-balanced snack that satisfies both your taste buds and your body's nutritional requirements.

The centre features a soft protein blend, carefully formulated to provide an enjoyable texture. Wrapped in gooey caramel and topped with crunchy protein crispies, each bite delivers a satisfying mix of chewiness and crunch, followed by the rich taste of chocolate. Despite the indulgent flavour, each bar is low in sugar, making it a guilt-free option for anyone looking to maintain a healthy diet.

Containing a blend of whey and milk proteins, the bar delivers essential amino acids that aid in muscle repair and growth, making it an ideal post-workout snack. With 20g of protein per serving, it helps to replenish and repair muscles after strenuous activity, whether you're weight training, running, cycling, or engaged in endurance sports. Additionally, each bar offers 22g of carbohydrates (depending on flavour), which are essential for replenishing glycogen stores that are depleted during intense exercise.

The Protein Bar’s low sugar content is another reason to include it in your routine. With less than 3g of sugar per pack, this bar allows you to maintain energy levels without the crash associated with sugary snacks. This makes it an excellent choice for individuals who want to monitor their sugar intake while still benefiting from the energy-boosting properties of carbohydrates. The combination of protein, carbs, and low sugar means this bar can be used strategically throughout the day to manage energy levels.

While the Protein Bar is designed to be consumed after a workout for optimal recovery benefits, it can also be enjoyed as a snack at any time of day. It’s particularly helpful if you're going more than four hours between meals, as the high protein content helps to curb hunger and maintain energy.

 However, it’s important to remember that while convenient, the Protein Bar is best used to supplement a balanced diet, which should primarily consist of whole food protein sources.

Key Benefits of SiS Protein Bar

  • High protein content: 20g per pack to support muscle growth and repair.
  • Low sugar: Less than 3g of sugar per pack, helping to avoid energy crashes.
  • Conveniently portioned: Two 32g bars in each pack for easy consumption on the go.
  • Balanced nutrition: Provides 22g of carbohydrates to replenish energy (flavour dependent).
  • Great taste: Gooey caramel, crunchy protein crispies, and a smooth chocolate coating.
  • Ideal post-workout snack: Best consumed within 30 minutes post-exercise to aid recovery.
  • Versatile: Can be eaten throughout the day as a protein-rich snack to sustain energy.

How does it work?

The Protein Bar is designed to work by delivering a carefully balanced blend of protein, carbohydrates, and low sugar to fuel your body and support recovery. The key ingredient is the high-quality whey and milk protein blend, which provides essential amino acids that your body needs to repair and build muscle after physical activity.

Consuming the bar within 30 minutes of exercise ensures that your muscles receive the protein they need at the optimal time for recovery. This quick absorption helps reduce muscle breakdown and promotes the growth of lean muscle mass.

In addition to the protein content, the bar provides a moderate amount of carbohydrates, which help to replenish glycogen stores that are depleted during exercise. By restoring glycogen levels, the bar helps to maintain energy and prevent fatigue, allowing you to recover more effectively. The low sugar content ensures that you avoid the sharp spikes and crashes associated with sugary snacks, keeping your energy levels stable throughout the day.
