Thread: protein--isolate vs concentrate

I may be wrong but Im under the impression that Isolate is absorbed faster so the best for you would be reliant on the timing of your meal and your overall goals

Like I said, not sure if that is accurate lol

I think isolates = more protein per serving.

Isolate has no lactose and minimal fat

concentrate has a little lactose and a little fat

hmm...it sounds like the difference is negligible. from what i understand, a little fat in your meal tends to be beneficial.

thanks

You should have no fat in your pre-workout shake or your post workout shake. Prima Force has a great grape flavored whey (the watermelon is great too).

why not fat in post workout? i have been making weight gainers after i lift with fat in them

I'm sure the little amount of fat in protein powder is not going to make any difference. Besides, I remember Emma-Leigh arguing that this rule is true to some extent, but no so much that it will make a significant difference in your gains.

Because it slows absorbtion rate. I just would add tons of PB or flax/efa's to my PWO shake.

yeah, thats what i do.... so you guys DO want fat in it?

or you don't?

are you guys talking about post PWO? or PWO shake?

Basically WPI is a more refined product - it undergoes more filtration than a concentrate. This means that more of the carbs (lactose) and fats are removed leaving you with a higher % of protein (but it also costs you $$$$).

Generally a good PWI will have ~90% protein with fat and carbs at < 0.5-1% where a concentrate can vary from very low protein (but usually 80-85%) with about 5-10% carbs and 5-10% fat.

If you get a GOOD concentrate (so the protein is up near the 85% ish mark) the difference is very little - and so the extra cost of the isolate is probably not worth it.. But if you use a poor quality WPC you are better off up-grading.

As to which I would use PWO?? Once again - it depends on what you use. If you have a good quality WPC then it probably doesn't really matter - but if your WPI has a high fat content (>5-7% - or more than about 2.5g per oz) then PWO I would switch to a WPI.



Here are some articles on the difference:

what do you recommend ms. leigh?

should i keep adding fat to my PWO shake? I'm completely confused on this madder..... people in this thread has said NO to fatin PWO, but then add pb? pb has fat.... which was why, at least to my understanding, why its in the shake.... should i add the fat or remove it?

There should be no fats added to your PWO shake..

worddddddddddddddddddddddddddddddddddddd
thanks
ive read from so many guys that adding pb to the PWO shake is beneficial..... ive been having like 3 servings in each one too aha..... tastes so good

would that change if im trying to gain strength and weight?
and im guessing its alright to add it to other shakes aside from PWO

thanks

what did you mean by this?
it seems contradictory..... or is that just me looking at it wrong

thanks

Ask her if juice or milk is better for PWO .

this discussion is really enlightening...that makes a lot of sense--since fats slow down protein absorption, the worst time to have fats is right after working out.

what's the argument against taking fats before working out? is it the same deal, because is slows down protein absorption? i had read somewhere that taking some fats before working out is good, because it provides slow-burning energy that can improve performance during the workout. is that bull?

no, i believe that, as I've learned oxidative sources start to be used after the duration of 2 minute activities...

but in post workout, I have read how so many people put peanut butter in their post workout shakes...... like a lot. This is wrong I'm hearing, and Im confused on this...

if it slows absorbtion, then why do so many people do it? it cant be just for the taste.... why would they do that

Yea, this was a typo.. "WOULDNT add"

ohhhhhhhh alright cool man
would you guys recommend using it in other shakes though? much as post post workout?

I stick with the concentrate. Yes, isolate does have a couple more grams of protein, but I really don't think that should make or break you decision. Although the concentrate I buy has 2g of fat per serving, I could care less. I don't think 2-4g of fat in your post workout shake is going to prevent it from being digested quickly. It might make a minor difference, but if it's all liquid then it's going to be digested very quickly anyway.

There are also other benefits to the fats in whey. They contain growth factors, certain EFAs, and studies suggest they promote immune system and intestinal health.

So why does Muscle Milk have so much fat and recommend it as a PWO drink? Are they just nuts or what?

they wanna milk your wallet

well they didn't get anything near retail on me anyway I like it, it tastes great and gives me protein.

They also claim it burns fat. What a load of horseshit. How does anything with calories burn fat unless they also load it up with amphetamines?

yeah... they say there are so many more benefits on it compared to other products.... i dont believe it at all pretty much either

but taste? yeah muscle milk tastes GREAT! So good....
