Thanks for posting Reflex and Drew.
In response:
Cream of post workout proteins?
In a word no.
Well, as you pointed out this is a question. I was hoping my concluding 2 paragraphs summed my feelings up ok. Have a read and you'll see my thoughts.
At Reflex Nutrition we've been looking at protein hydrolysates for over 12 years, we turned the offer of selling casein hydrolysate down because a lack of scientific evidence.
Whey Protein Hydrolysate is scientifically proven to raise insulin levels, I don't know why you missed this James?
Here is the study: http://www.carbery.com/...Posters%20LoRes%20V2.pdf
You'll note that whey protein hydrolysate provides a 28% increase in insulin over ordinary whey protein isolate.
Scientific evidence is a term which is very broad. I'd say there's more scientific evidence for CPH than loads of other supplements, including some you sell.
And the term 'scientifically proven' is not one I like to use, because in science little is 'proven'; more 'evidence for'.
I didn't see that one study, no. But does one study make the evidence conclusive? Definitely not, and I made the point about evidence in my article. Like Drew says, sure there's lack of good evidence, I agree.
Nevertheless, I wrote this article for information for readers to arm themselves with more knowledge when purchasing proteins.
When we were approached to sell the said Casein Hydrolysate we asked if there was any proof that it was any better than Whey Protein Hydrolysate. There wasn't any proof, so we don't use it.
We certainly DO believe that whey protein hydrolysate has its benefits for athletes.
You'll never find proof for anything, especially for supplements. I agree though, the evidence is weak. But people should be able to make up their own minds. There is theory though, and that's a hell of a lot more than there is for a bulk of other supplements.
