As protein is vital for muscle growth and repair, protein supplements are the most popular sports supplements in the entire world, especially whey protein. Typically, whey protein concentrates are more common than isolates, because they are cheaper. Whey isolate and concentrates are both derived from cow’s milk and are obtained when the milk is separated into cheese.However, whereas whey concentrates will typically be between 70 and 80% protein per serving, whey isolates will be around 90-97% protein per serving. This means that you get more protein per serving, and less (only 5%) fats and carbohydrates, than regular whey protein.
Whey isolate undergoes highly advanced filtration processes, which are typically micro and ultra-filtration processes. This means that the protein molecules do not become denatured, and so obviously, as a result, they are still as potent and effective. The proteins are high in bioactive peptides, and lactose, fats, carbohydrates, and other unwanted ingredients, are filtered out.
