SiS Overnight Protein (Vanilla) is made from high quality milk protein in a 50:50 blend with whey protein isolate for a great taste, providing a source of slowly digesting protein with a high amino acid profile to support lean muscle growth and maintenance as you sleep.

Milk protein is over 80% casein, which is a slowly absorbed protein and around 20% whey, which is rapidly absorbed. Whey protein stimulates the rate of muscle protein synthesis with its high leucine content. Each serving contains 26-27g of protein per serving and low levels of carbohydrate and fat.

So why should you take SiS Overnight Protein? Well, sleep is one of the most important aspects of recovery and is often unappreciated by many athletes. Regularly feeding 20-25g of protein every 3-4 hours is the best way to support the growth and maintenance of lean muscle mass. Feeding during the night is impractical, so taking SiS Overnight Protein before bed allows quality sleep and quality protein delivery to maximise your training adaptations.
