Blended protein sources were created to combine the benefits of different protein sources. A common ingredient:
- Whey protein isolate
- Whey protein concentrate
- Whey protein hydrolysate
- Casein
- Egg protein
All ingredients are complete protein sources, containing all 9 essential amino acids.
The two types of protein found in milk are whey and casein. Whey protein is the most popular protein formulation, all 3 types are rapidly absorbed, but the fastest absorbed is the pre-digested hydrolysate, followed by the isolate an then the concentrate. Whey provides your muscles with instant nutrients.
The second milk protein, casein, in musch slower absorbing, providing nutrients for up to 8 hours. This way, fast and slow absorption proteins provide you body with a continuous supply of protein. And egg whites (albumin) provide a different amino acid profile that can make your body's supply of amino acids even more efficient.
Why is protein intake important?
During sport and physical exercise, the proteins that build up the muscles are damaged (so-called micro-tears). To heal this, an inflammatory process occurs, during which the inflammatory cells digest (catabolize) the damaged muscle fibres and new protein is produced (synthesized) to replace them. - This explains muscle fever.
The processes of protein synthesis (building) and protein catabolism (breaking down) occur in parallel in our body. The main requirement for building muscle is that protein synthesis is positive, i.e. more new protein is built in than is broken down - a growing number of studies are finding that even a calorie surplus is not necessarily required to build muscle, so with the right diet and training protocol, you can increase muscle and reduce fat mass at the same time.
With adequate protein intake, stimulating muscle growth can help preserve muscle during weight loss. Adequate protein intake is essential for all people.
