Description

Wrapped in smooth chocolate and layered with gooey caramel and crispy protein pieces, the SiS Protein Bar is more than just functional, it’s enjoyable. Its low sugar content (under 3g per pack) means you get the nutritional support without the crash associated with typical high-sugar snacks. The bar also contains 22g of carbohydrates (flavour dependent), helping replenish energy stores post-workout or throughout a busy day.

This bar has been crafted to make recovery easier and tastier. The dual-bar format allows flexibility. Eat both bars after training for full recovery support or save one for later to bridge a gap between meals. With a texture that blends chew and crunch, and a rich chocolate coating, it delivers both flavour and function.

Ideal for consumption after strength sessions, long runs, or high-intensity training, it’s also a great snack when you’re on the move. The combination of protein, carbohydrates, and low sugar means it fits perfectly into most active lifestyles, providing fuel and support when you need it most.

How does it work

The SiS Protein Bar supports muscle repair and energy restoration by combining fast-absorbing protein with replenishing carbohydrates. The protein blend provides essential amino acids, which help repair muscle tissue damaged during exercise and support lean muscle growth. When consumed post-workout, the protein is absorbed efficiently, kickstarting the recovery process.

The moderate carbohydrate content helps refill glycogen stores, which are depleted during endurance or strength sessions. Together with its low sugar formulation, the bar ensures a steady energy supply without sudden crashes, making it an ideal recovery and energy-maintenance solution.
