Based on the description, the Ultimate Mass Shake mainly contains dextrose and maltodextrin as carbohydrate sources and whey protein concentrate as a protein source.

• Dextrose: Dextrose is a simple sugar, also known as glucose. It is quickly absorbed by the body and is therefore well suited for a rapid energy boost, especially after training to replenish glycogen stores.
• Maltodextrin: Maltodextrin is a carbohydrate derived from starch. It consists of short chains of glucose molecules and is rapidly broken down in the digestive tract, resulting in a quick release of energy. Maltodextrin is often used in sports drinks and nutritional supplements for athletes.
• Whey protein concentrate: Whey protein is a high-quality protein source derived from whey. In addition to protein, whey protein concentrate also contains smaller amounts of fat and carbohydrates. It is easily digestible and provides a good amount of essential amino acids, which are important for muscle growth.

The vitamins added to the shake (vitamins B1, B2, B3, B6, pantothenic acid, biotin, B12, vitamins C and E) contribute to overall nutrient intake and can be particularly important during intense training phases. However, please note that dietary supplements should not replace a balanced diet, and it is important to adhere to the recommended dosage.
