X-Post re Protein Drinks

does anyone know how long a protein drink is good for/effective if I mix it up before I leave home in the morning?

How soon do I have to drink it.

Thanks!

 About once or twice per week, I mix a large container in the morning, and then put it in the fridge  at work to use through out the day.

Does it mave milk? What kind of protein drink are you making?

I would just use good common sense and only make what you will drink in one day, and keep refrigerated.

I do use milk, I can't drink w/water YUCK to me.

I use GNC and usually add fruit (frozen blueberrys, strawberry's)

I really thought I had read that it starts losing protein effectiveness after a couple hours but I can't find the reference.  I always aim to finish within an hour or two of making.

Lisa,

that's what I thought too, but I can't find it anywhere either.

Thanks!

I've always treated mine like milk. ( even tho I make with water )...always keep it in the fridge.  I made up mine the night before and grab them in the morning to go....I've even made some up a few nights before and got to busy to grab them...

I was toild the best way to keep the shakes are in the freezer . For protein breakdown  reasons.I am not sure if that really answers your question but it may be helpful for others.

My understanding is that the quality of a protein drink decreases after 6 hours, and that if it is kept refrigerated, so it is best to mix up right before you drink it. I got that info from a nutritionist online at one of the protein powder companies, I don't remember which one though.
