Protein Isolated and hydrolyzed

What are whey isolate and hydrolysate?

Whey isolate and whey hydrolysate are particularly refined forms of whey protein. They feature a high protein content, a reduced amount of fat, sugars and lactose and an excellent bioavailability, which is why they are highly appreciated by people who play sports and look for a high-quality protein supplement.
