Hey Proteinfreak,
There are three types of protein.
Concentrates: Extracted from food using acid or enzymes and heat, they contain 60-80% protein, the rest being carbs/calories.
Isolates: A step up from concentrates, protein isolates are subjected to an additional filtering process to remove fats and carbs. You can expect to get 90-95% protein from this type.
Hydrolysates: Taking it up a notch, hydrolysates are created with additional heat & acid/enzyme processes. During this method, bonds between amino acids are broken so your body can absorb them more quickly.
However, during this process whey protein is stripped of critical nutrients. The result can be a much less effective protein contaminated with additives that are synthetic among other contaminates that are clearly counterproductive to building muscle and getting results. It is also a contributing factor to poor digestion and tolerance.
So we recommend cold-processed whey protein.
