MAP imo
Invalid Link Removed
After checking into this one and viewing the profile, I don't think this would be a good choice for a casein. What's the whole point of a casein protein? Slow release and extended absorption. Used for extended periods without food intake to supply a continual flow of amino acids and reduce the catabolic effects of sleeping or going for several hours without food intake. This is from the same web site posted for MAP (my emphasis added for point):
"MAP delivers amino acids
quickly and fully. It's the most efficient way to get them to your muscles, short of injecting.
No other protein or amino acid absorbs better than MAP. (1) The amino acids in MAP are
carried right through the stomach walls without any digestion required.
Tiny Peptides -- A Clear Advantage
MAP is 100% pure pre-digested casein protein. This means that the casein protein has been broken down into small peptides of two or three amino acids.
The amino acids in MAP absorb better than amino acids in single form."
So they claim they created a casein protein with extremely small amino acid peptide chains that are absorbed so well and so quickly that they even
bypass digestion and are "carried right through the stomach walls". This last part is physiologically impossible since very few substances can be absorbed through the stomach walls such as aspirin and alcohol. The stomach doesn't not absorb nutrients and proteins, the small intestines do. The stomach is merely a holding and mixing chamber which breaks food down
to be absorbed.
Enough on that though and on to the point. Assuming all things claimed are true, why would anybody want to take a casein if it moves so rapidly through your system that an hour or two later, it's no longer available for nutrient absorption? That means that the rest of the night (still a good 6 or 7 hours) you will go without any amino acid release to help stave off catabolism and limit recovery. This is, of course, assuming that it is taken as a casein where prolonged AA acid release is desired such as pre-bed or long periods before your next meal.
Casein, such as micellar casein is known and used for it's slow break down and thus the prolonged and perpetual release of amino acids for several hours. That sounds much more effective to me. Some companies such as XF add isolate to their casein (i.e. UP 2.0) to provide some essential AA that can be used much sooner since it takes awhile for the casein to break down, thus providing a more balanced and synergistic flow of peptides.
from Protein Factory's site:
"Monster V is now the King of Slow Release Proteins. Our brand new Monster V Protein has a molecule size twice the size of casein, therefore taking it twice as long to digest. Monster V Protein is made in the U.S.A. using the Cohn V fractionation process. This process results in a completely 100% undenatured protein, jam packed with bioactive peptides and subfractions. Use Monster V for anti-catabolic, sustained release protein or a night time protein."
This makes more sense to me, using a casein for its prolonged digestion and sustained AA release.
I use ON vanilla cream flavor. Mixes well for Cassein. Taste is good. You can get it cheap if you get 4lb containers. Last a long time if you're only using it at night.
That's how I do it. I love UP 2.0 but it gets pricey. I have ON's 100% micellar casein, chocolate supreme, and add some isolate to it as well. Tends to last pretty good. I'm not too keen on their chocolate peanut butter and the raspberry smoothie wasn't my favorite flavor.
