This statement (put out by the manufacturer), and a couple of other statements (also put out by them) are the only things I've seen so far.
It isn't something that interests me, personally....
"Velositol is a patented combination of amylopectin and chromium that is designed to work as a perfect partner to protein. Velositol's highly soluble amylopectin stimulates insulin's safe and controlled release, while chromium enhances insulin function and increases muscle cells' sensitivity to it. Together, these nutrients enhance insulin's ability to transport amino acids into muscle cells where they supply the nutrients needed for MPS."
This is also found in @Olympus Labs protein powder and the outright bars breakfast series
could expand on its benefits in conjunction with protein
Velositol is a patented, revolutionary ingredient, that when used with protein is designed to accelerate and boost muscle protein synthesis (MPS), a key to enhanced muscle growth, lean body mass, and quicker muscle recovery.
From the OL webpage on superior protein
Velositol® is an amylopectin chromium complex that doubles the power of protein by enhancing the insulinogenic response, increasing amino acid uptake, and therefore increasing muscle protein synthesis.
how much is really makes a difference? Hard to really say. I have been through many tubs of the OL protein and compared to taking a whey blend or other whey product don’t see much of a difference in the grand scheme of things.
