Protein Shake Shelf Life


#1

Is it better to make protein shakes as you need them, or could I just make a big pitcher? I do not know whether or not the pitcher of protein shake would go bad if I do not go through it quickly enough.


#2

It will taste like total shit and have a disgusting consistency long before it “goes bad” i would imagine.

Why on earth would you want to do that?


#3

I mix a shake up each night to have first thing in the morning. I like the consistency better compared to shaking and drinking right away.

Make sure to refrigerate it though. And it will have some stuff settle out that needs re-suspended, so a big pitcher of it might not be the way to go.


#4

If you blend fruit into your shake it will taste pretty bad after only a couple of hours. Some kind of reaction occurs between the protein and fruit.


#5

Depends on what you put in your shakes. Mixing them right before drinking is best, but if you absolutely must make them ahead of time (to drink on a construction jobsite for example) I think a common-sense rule of thumb would be ‘drink the same day’ at the longest.


#6

A ton of free amino acids floating around in water will put most microorganisms into hyperdrive. Just mix them as you need them.
