Whey Isolate vs Casein

ehaleyhoward2778

For those of you that use protein powders as a main source to hit your macros while eating at/near maintenance with hopes to reduce overall BF, can you tell me the differences in Whey Isolate and Casein protein? I use "Now sports Whey Isolate naturally unflavored" and love it mainly because being that it's unflavored I can add it to oatmeal, smoothies, yogurt etc and I don't get that awful protein powder taste I hate. I use 2-3 scoops of it a day (110cal 25gp per scoop) I put 1 scoop in my oatmeal in the morning post workout and a scoop in my midday smoothie and sometimes a scoop in some yogurt or something else I make around dinner.
From what I've gathered whey is faster digesting than Casein, but I can't say I exactly understand the importance of that.
My question is, how will I benefit from buying some Casein and incorporating it into my diet as well, and when, if at all is it more appropriate to use?

Thank you all

For your needs, it doesn't matter at all.

Can you explain?

You're using it to supplement your daily protein needs, correct? A very basic breakdown of whey protein powder types:
-whey concentrate is the most basic and cheapest to hit your protein goals
-whey isolate is more rapidly absorbing and generally used post workout but can be used any time of day
-Hydrolyzed whey (also in isolate) is the same as isolate but further broken down and more rapidly absorbed
-Casein breaks down slowly and is digested over a greater period of time; recommended to drink before bed or over longer periods of time you will not be consuming protein

So in your context it doesn't matter, but I would use a regular whey to save some $.

Interestingly, Alan Aragon had linked to a study once upon a time that showed Casein as being superior to whey for post workout protein synthesis, which is the opposite of what was expected. I'll see if I can find it.

That being said, whole milk proteins (20% whey, 80% casein) seem to outperform both on their own.

I use casein or pea protein when I want the slower release to keep me from starving during the day or rebuild muscle when I sleep and whey right after a weight lifting session when I want to feed my muscles fast.

I can definitely feel a difference in the fullness factor between Isolate and casein. Casein keeps me fuller for longer, plus it mixes up thicker than whey isolate, so i choose casein.

As for the protein powder taste.. What brands have you tried? There are some yummy ones out there. My top picks are Optimum nutrition choc/peanut butter (Casein) and any of the Quest protein powders (Isolate+casein). Both make oatmeal taste so much better.

In addition to the above responses, one potentially major difference could be a prolonged satiating effect of Casein.

Yes. Casein is thicker and digests more slowly (and tastes better, IMO). I prefer the best of both worlds by using a whey/casein blend. I've been using Trutein and really like it, but I recently tried a few samples of Quest (also a whey/casein blend) and it's pretty good also.
