Product Overview

Why Choose?

  • Rebuild
  • Recovery


Overnight Protein (Chocolate) 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 synthewith its high leucine content. Each serving contains 26-27g of protein per serving and low levels of carbohydrate and fat.

Key Features

  • Slowly digested milk protein
  • Fuelling gold medal winners since 1992
  • Contents: 1kg Tub (28 Servings)

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.

Very nice and good snack

Patrick Jones


Nice texture and taste

Michael Draper


I enjoy a warm mug of this every evening approx. 1 hour before sleep. No unwanted stomach reactions and I don't wake up in the night feeling hungry.



Quite a fine powder but a good slow release protein.



It is a very light protein, and fills you up , perfect for alternative dinner



Great way to recover, beats a normal night time drink or alcohol. Great when training hard.

Mr. Joe Beer
