During rapid weight-loss, when protein supplements are the main source of dietary protein intake, it is essential to choose products that contain all the essential amino acids (so that the body can use them and make healthy tissues)
It’s also important your protein has a high digestibility score – that is - your body can use it!!
Scores of as close to 100 as possible are desired to indicate that it contains the appropriate amount of amino acids that the body needs.
Protein supplements that are made from whey, casein, soy and egg whites have a digestibility score of 100. It is important to recognize that many of these protein sources are sold as either concentrates or isolates.
IN GENERAL:
Isolates tend to have a higher concentration of protein than concentrate forms.
These products may be beneficial to those patients who have lactose intolerance, and have a smoother feel to them.
Whey protein concentrates have a lower concentration of protein and higher concentration of lactose
