Bulk Supplements Direct have formulated the Ultimate Protein Blend comprising of Whey Protein Concentrate, Whey Protein Isolate, Milk Protein Concentrate and Milk Protein Isolate. Using a proprietary blend we have created a multi-protein formula that allows for both fast, medium and slow release of Protein for your body.

Can you explain to me how those super intelligent digestive emzymes, acids etc in the digestive system can differentiate these differing proteins and ensure they are all digested at differing frequencies. Its not possible!

I believe when various proteins are combined then the release mechanism also changes? Forgive me if I am wrong. If I am right then please change the description.

The make up of Milk Protein is split amongst casien and whey - the release of AA in the bloodsteam and through digestion would be at variable rates and thus the NET overall release would depend on the ratio used and whether the Proteins are predigested or not.

In the case of this blend its a mix of two sources Milk and Whey, and one being able to be processed faster and the other not [Isolate and Concentrate].

So to answer your question - depending on what the ezymes are doing and the digestion process - some take longer to break down than others - which would mean the speed at whist the AA's are released would differ.
