Protein Blends from manufacturer Amix is a category of plant-based and animal protein blends that contain multiple sources of protein. This can be a combination of multiple types of whey protein powders, that sometimes contain an admixture of micellar casein, which is more slowly absorbable. Perhaps less common is the combination of different plant-based protein powders. Combining multiple types of proteins into one can result in better properties of the resulting protein blend. For example, it can be a combination of fast and slow release proteins. Similarly, protein blends can include multiple sources of protein, which have a different amino acid spectrum.
This is quite typical for plant-based protein powders, as in their case it is best to combine legume and grain protein sources. The result is usually a protein blend with more favourable ingredient profile and a better amino acid spectrum. A typical example of an animal protein blend is FueSix. A prime example from the ranks of plant-based protein powders is for instance the BIO Vegan Protein.
