Collagen Protein Isolate is the worst and basically useless protein source. Hard for your body to even process it. So you are not supplying your body with useful protein that you think you are. Stay away. Do your own research on Collagen Protein Isolate and you will see.
These little small shots of protein pretty much speak for themselves. It is a small shake, less than 4 ounces o believe. But these things have 42 grams of protein, they are fat free, and also are sugar free. So as far as all that extra stuff that people dont want in their protein shakes, these are great for strictly straight protein. The taste os not bad, they are definitly tolerable. So if you dont have a whole lot of time, these are the ones. They are already made up. So you can grab n go.
Overall, this is a pretty good Ready-to-Drink protein shake. I do like muscle milk if you are looking to put on lots of muscle. There are some better options out there, but if you are looking for a quick way to uptake your protein, this is a good option. It has a decent taste, and a pretty good price. Overall, I would suggest trying this shake.
IDS New Whey RTD is great ! I highly recommend it!
