Active ingredients & science

The protein consists largely of fast-absorbing whey protein, known for its high biological availability and essential amino acid content, including branched-chain amino acids (BCAAs), which are important for muscle building and recovery.

The formula is designed to ensure good absorption, meaning that the nutrients can be efficiently absorbed and utilised by the body.

Benefits & uses

  • Flexible use: Can be used as a meal replacement or supplement when it is difficult to consume enough food.
  • Easy to mix and consume: The powdered form lets you quickly prepare a nutritious shake wherever you are.

Directions & dosage

For optimal results, mix 2–3 scoops (approximately 150–225 grams) with 300–400 ml of liquid, either water or milk, depending on your preferred consistency and taste. If using the product as a meal replacement, it may be beneficial to combine it with a balanced diet to ensure adequate nutrient intake. Remember to adjust the dosage to your individual needs and energy expenditure.
