Whey concentrated
Originating from lactoserum, it’s the most common protein preparation, containing 80% proteins on average. Since it includes carbs and calories, it’s often used for muscle hypertrophy. If your workout objective is to gain muscle mass, whey concentrated can be a very interesting option to incorporate into your food diet. You should preferably take it with your breakfast or after your workout.
Whey isolate
This is a “purer” form in terms of proteins, because proteins make up for 90% minimum of the preparation. Isolate has a small amount of carbs and lipids, and also lactose (milk sugar) and cholesterol. This allows the body to absorb its amino acids quicker. Besides, its leucine concentration enhances muscle protein synthesis, so that muscle growth and fat loss are catalysed.
Originating from a series of successive cold filtrations which do not denature the proteins, this preparation is more costly than whey concentrated, but is optimal for people with a weak digestive tract, or athletes in their cutting phase.
Other forms of whey
You can also get whey via ion exchange, but the acidity the process involves damages part of the amino acids, and affects their properties.
Another option is hydrolysed whey. During this process, the long protein chains (peptides) are broken down by an enzymatic reaction. They are so to speak pre-digested, which allows for a very fast absorption of proteins by the body, but this process is very expensive and the result is often a product with a bitter taste.
