  • Isolates – They are processed to remove fat, lactose but are also low in bioactive compound – it contain 90% protein by weight. Isolates are very helpful for individuals with lactose intolerance as it contains very small percentage of lactose.
  • Hydrolysates are partially digested and hydrolyzed. The purpose is to make them easier for metabolism. However they are usually very costly compared to other forms.
