PTG Protein to go drinks

Has anyone tried these ? No sugar, low cal , low carb, 28 grams of protein..A friend of mine just told me about them and was looking for some feed back.. Thanks Krista..

They are not good for WLS patients as they contain collagen protein

"What protein supplements should be avoided?

Collagen-based protein supplements are not a good source of high-quality protein and should not be used as the sole source of protein intake in WLS patients. Collagen-based protein supplements do not contain all of the indispensable amino acids that the body needs. When consuming collagen-based products as your sole source of protein, the loss of lean body mass can occur despite meeting your daily protein goals."
