Does protein degrade after a protein shake has been mixed?

Okay, so I've heard 30 different stories. Can anyone tell me if its okay (not okay) to refridgerate a protein shake overnight after I have mixed it? (My shakes usually include unsweetend almond milk, EAS whey vanilla protein, and a fruit of some sort)

I like to grab-n-go in the morning since I usually go to the gym around 5-5:30am, so I was wondering if the protein is alright when it sits in the refridgerator all night.. Some say it degrades and you get about 30% of what you would get if you consume right after mixing, others I've heard its alright for up to 2 days..

Please let me know, if you could give any backup as to why that would be great too..

    I have no idea. But, if you're concerned about it you can measure out your almond milk into your shaker and then just add your protein powder before you leave. It's not exactly grab-and-go, but it only takes a minute.

    Think about this for a second and you'll have your answer.

    Where does whey come from?

    All biological things degrade. Protein is no exception.

    While technically true, the rate of degradation during the time-span between mixing and consumption will be trivial at best.

    Spoilage will occur long before significant protein degradation.

    OP use a glass of milk as an example. If left out or not consumed long enough, what happens?

    Same thing with whey protein.

    Furthermore if you are starting with a powder, it is beginning from a degraded state. The less time it sits the better, but to the exact amount of time it takes before its useless.... will vary based on processing.

    Do you have any evidence to back this statement up? Or are you just talking out of your backside?

    So this morning I threw my protein powder in the mixer and ran to work. I added water when I got there. What's wrong with using water?

    I know where whey comes from, but its being refridgerated for a max of 10 hours.. thats why I'm asking. I'm not leaving it on the counter to sit overnight..

    And now it goes south :-)

    I have evidence of both.

    Nothing is wrong with using water, but whey protein degrades. You should consume it as soon as possible. I was just using milk as an example of a biological product.

    Because this is what I have every morning and the water and protein mix is getting boring?

    Not trying to be snarky, just using the Socratic method.

    Think about it this way: are you concerned with protein degradation when you leave milk in the fridge overnight? Probably not.

    Same thing with whey protein.

    Is it going to completely degrade in a matter of 10 hours refridgerated.. Milk degrades but not overnight..

    Care to provide this so-called "evidence"?
