Proteinex Liquid Protein Drinks
by Cindy on 4/6/2013
I love these products! They taste really good in tea and fruit drinks and they really provide the protein I need daily. I wouldn't drink liquids without them. The lemon lime is my favorite but the apple is good as well.
Best tasting liquid protein ever.
by MICHELE on 8/31/2012
I love this liquid protein. I ordered the small bottle of grape flavor just to test it. I love it so much that I came back to order the 30 oz. The texture is the best..not thick like other liquid proteins. There are times when I think it is too sweet and other times it craves my taste for sweets. I am hooked on this brand and will always return.Grape is my favorite flavor, but i am willing to try the other flavors soon.
You Get Used To It

No liquid protein tastes wonderful, but this is definitely better than most I have tasted. Over time, I have become accustomed to the taste. The amount of protein per ounce and low calories make it great for Bandsters.
It is just what I needed
by Andy on 2/11/2011
My first time trying such a product. I have the LemonLime flavor. As far as taste goes it is okay. But it is a thick substance that does need to be mixed well with your choice of liquid. And for me personally it has to be sipped slowly. My Lap band is set pretty tight and the viscosity of the drink (even when mixed with water) when it hits my pouch sometimes feels like it wants to come back out. Don't get me wrong it is nothing thick like cooking oil but it has some weight to it. I put up with this slight inconvenience because of some skin wound issues I have, and since taking this product the extra protein has cleared up those problems. And my lab reports are great. So for me it is great.
Not that bad of a taste
by nicole grady on 10/8/2008
Doesn't really taste THAT bad. It's kinda sour, like Sour Patch Kid candy.

Proteinex 18
by Beverly on 6/29/2008
You have to follow the review from another user for another liquid protein. All liquid protein is nasty! None is going taste good, but if you follow her instructions, you can get this down and be ok. Hold your nose and shoot the 1oz. down and then use something else to rinse your mouth with several times while still holding your nose and then drink or eat something that has a lot of flavor and then let go of your nose.

Good Price
by Miriam Maldonado on 6/3/2008
Please tell me if the free shipping includes Puerto Rico. The price in PR is very high and you have a good price. Thanks

Good product
by anne on 9/13/2013
As protein products go this is good. I mix it with 2oz suger free drink and it goes down nicely.
Give it and cherry a try. I like them both.
Love it

I have used this product for over a year and I has helped me maintain my protein intake. It also helps curb my hunger pains. I also recommended it to my sister, who has been using it for several months now,

Proteinex-18 Liquid Predigested Protein
by Roe on 7/24/2012
This is the worst tasting product that I have purchased from this site. Bad after taste, if you can get the teaspoon even down to where it will stay there.
