Suitable For
This food supplement is intended for physically active adults seeking a slow-digesting protein source to support muscle maintenance during periods of extended fasting, such as overnight or between meals. Protein contributes to the growth and maintenance of muscle mass and the maintenance of normal bones. Due to its slow-release properties, micellar casein helps reduce muscle protein breakdown (anti-catabolic effect) and promotes satiety.
Instruction
Dose: Single/Serving Size: One scoop (33g). Maximum Daily Dose: Consume 1–2 servings per day depending on individual protein requirements. Do not exceed the recommended daily intake from all sources.
Usage: Add one scoop (33g) to a shaker with 240–300ml of cold water or milk. Shake vigorously for 30–40 seconds. For best results, consume immediately after mixing.
