2.5 oz protein shakes

Ok so I has questions earlier about different types of protein shakes. Some have collagen and some whey.... I found one last night that is 2.5 oz and has 28g of protein. I had an appt today with my dietitian and she said it was fine even though it has some collagen in it... So I asked her how many grama I should count it as towards my protein and she said all 28. I tried to post pics of it... But can't figure out how to post them from my gallery on my phone... What do you guys think??

if i used it,which I wouldn't personally,I would not count it toward my protein for the day. collagen is fine for hair and nails,but does little for nourishing our muscles. Our heart ,lungs,kidneys and body muscles don;t benefit from collagen.
