Protein shots/tubes

i dont think they're BAD for you, per se, but they're not as effective a source of protein.

Thanks Karen!!
I will let my friend know....she is the one that told me about them......

Collagen protein is not easily absorbed and it is completely lacking in amino acids that our bodies need.

Here is a good explanation with respect to the need for amino acids:

For anyone that can't stand the milky shakes, here is what I drank the week I was on clear fluids.  It's 100 percent whey protein isolate and the flavours are very tasty.  They are about $5 per bottle but worth it if you can't get the milky ones in.

Just make sure you get the zero carb one.
