Understanding the biology of proteins from milk.
Your body uses proteins primarily as a source of amino acids, which need to be delivered in an optimal ratio to meet your body’s needs. Milk-based proteins have the highest quality proteins and deliver just the right ratio of amino acids to humans.
Specific amino acids have unique roles. For example, leucine has been widely studied for its role relative to muscle protein synthesis and weight management.
But a natural protein is much more than just the sum of its amino acids. Amino acids are present as peptides which have their own bioactive functions (some have a role in lowering blood pressure, for example).
Many “minor” proteins found in milk have their own biological functions and role, such as natural antibacterial properties and many other bioactivities. Proteins from milk are also packed with important components of the body’s defense system.
It is this unique combination of amino acids, bioactive peptides, and major and minor proteins that make proteins from milk so functional and deliver the strong inside as no other protein ingredient can. Some ingredients also contain important minerals and vitamins, in a highly bioavailable and digestible form. Some protein concentrates do contain lactose (varying amounts depending on their concentration). But isolates and caseins/ates are virtually or totally lactose free.
