What we think

We do our best to prioritize recovery because that’s how we get the most from training.

The new Protein Bar from Science in Sport is designed to provide a quick, convenient way to get in the nutrition you need after exercise. It’s perfectly packable for taking it with you out the door and having something to kickstart recovery. No powders, mixing, or hangry attitudes necessary.

It contains a blend of carbohydrates, protein, and electrolytes (along with vitamins and minerals) to replenish your fuel stores, rebuild your muscles, and help you repair following a hard training day.

Rapid replenishment of your glycogen stores and the provision of protein helps you to get the most from your training and reduce your recovery time between training sessions, making sure you’re ready to go for your next workout. SiS Protein Bars contain a high-quality blend of whey, casein, and soy protein(s) that amounts to 20g of protein along with 12g of carbs.

Not to mention, it's Informed Sport Certified so you can feel good about making this your post-workout recovery choice!
