Creatine plays a critical role in the body's energy system by helping regenerate ATP, the primary energy source for muscular contractions. By maintaining higher levels of muscle phosphocreatine, SiS Creatine helps fuel those repeated efforts that demand power, strength, and speed. For best results, it’s recommended to take creatine post-exercise and alongside food, where insulin and muscle contraction both enhance uptake.

As with all Science in Sport products, SiS Creatine is Informed Sport Certified. This ensures that every batch is tested for banned substances to the highest standards, giving you peace of mind whether you’re a professional athlete or just training hard to meet your goals.

Whether you're looking to boost performance, speed up recovery, or build lean muscle, SiS Creatine is a trusted supplement that fits seamlessly into your training routine.

Creatine works by increasing the availability of phosphocreatine in your muscles, which is used to regenerate ATP, the molecule that fuels high-intensity, short-duration efforts like lifting, sprinting, or jumping. Without enough phosphocreatine, your ability to sustain these efforts drops rapidly. Supplementing with creatine allows your muscles to produce energy more efficiently, helping improve performance and potentially aiding in muscle growth and recovery.

While creatine is naturally present in small amounts in foods such as meat and fish, most athletes cannot consume enough through diet alone to significantly raise their muscle creatine stores. SiS Creatine offers a simple and effective way to top up these stores consistently and safely.
