This gives me a solid base of nutrition at the start of the day. I noticed I don't crave sugary snacks in mid-afternoon which is a great bonus!!

Will order again

I add this to boost protein in many items, flavored waters, soups, chowders, broths etc, did not alter the taste of food or drinks. The flavored version is to much for my tastebuds. Will order product again it’s helping me get the protein that my dr want me to get
Great Protein Source

Love this product and add it to anything that has a liquid base from tea to jell-o. Easy way to get a quick 15 g of protein!
Not the best, but not bad

We are MRC clients and tried this because it is the closest that we have found to MRC's protein without adding sugar, carbs & calories. The flavor does not compare to MRC's and isn't good at all mixed in water; however, for the difference in price we are using it and just taking it straight without mixing. We do like that is comes in a bottle and we don't have to open individual packets for each serving. It serves the purpose and it's a better value, so we will probably continue to use it.
this changed my life

i have tried the whey protein and they are thick and terrible. however.. being that i had gastric sleeve 5 months ago and still cant eat much of anything i need a product that gets in loads of protein but very little liquid or food. i started with the small bottle of this proteinex and am SOLD. it doesnt taste good but it you can stomach it for sure( and trust me.. my new tummy doesnt like anything so if i can stomach it.. ALL can stomach it..lol). but this product takes me from weak and sick feeling do to lack of protein to feeling normal again! needles to say now i buy the BIG bottle and its worth every penny to feel normal again and to build those protein levels up! my yt channel where i talk about many things as well as my wls journey is BIGCOUZ52 on youtube. hope to see you there!

I have tried several of the Protinex Flavors hoping to find something that would work. They are ALL AWFUL! I couldn't keep the apple banana flavor down.
