Muscle-Building Workout and Diet

What’s up? This is Sean Nalewanyj, of
And in today’s video lesson, I want to talk about the issue of whey protein powder versus
casein protein powder. Which one is better for muscle growth and why? Now, most bodybuilders
who are following a standard muscle building diet that involves about a gram of protein
per pound of body weight are going to be making use of protein powders. It’s a very convenient
way to get some high quality protein in your diet and the streamlines that you’re not,
you know, consuming four or five, six meals a day all from whole foods. So, two of the
most common protein powders that you come across are whey protein and casein protein.
Now, the traditional advice that you’re going to hear on this topic revolves around the
absorption rates of each source of protein. Most people are going to tell you, whey protein
is a fast-acting protein, and so, it should be consumed at times when you need, you know,
a quick source of protein, such as first thing in the morning or post-workout. Whereas, casein
is a slow-absorbing protein, and so, you want to stick to that during times when you want
a prolonged release of amino acids, such as right before bed. Now, the reality behind
this is that, yes, some proteins are absorbed more quickly than others. But in reality,
all protein sources are essentially slow-digesting proteins. Most people really underestimate
the speed of the process of digestion and absorption. It’s not this rapid process that
happens very quickly. It’s a very complex process that takes place from the time you
put that protein in your mouth, until the time that it’s actually absorbed by your cells.
Egg protein for example is absorbed at a rate of about 3grams per hour. So that means, if
you were to consume, you know, just 20grams of cooked egg protein, it would take around
seven hours until that protein was fully utilized by your body. Now, there’s no one absolute
figure, but if you look at the research that has been done on whey protein absorption,
the generally accepted figure is that whey protein is absorbed at a rate of about 8grams
to 10grams per hour. Now, that’s if you’re consuming the protein on its own in isolation.
When you consume the protein in combination with other nutrients like other proteins,
carbs and fats, then the digestion rate decreases even further. So, the bottom line is if you’re
following a standard bodybuilding diet, you know, worrying about specific protein digestion
rate is actually pretty much a non-issue, you know. Again, whey protein, if it’s being
consumed at 8grams to 10grams per hour, and then even slower when you consume it with
other proteins, if you’re eating, you know, every three to four or five hours throughout
the day, which is what most people are doing, you know, you’re always going to have a readily
available source of amino acids. So, if the absorption rate of the protein is largely
irrelevant, then, you know, really what it all comes down to is just the basic quality
of whey versus casein. And when you look at, you know, in terms of overall quality, there’s
really — there’s really no contest. Whey completely dominates casein in every category,
just like whey actually dominates any whole food protein source that you can think of.
So, there’s really two main issues when it comes to assessing the quality of any individual
protein. The first is the biological value. And the second is the amino acid profile.
So when we’re talking about biological value, what we’re ultimately referring to is how
much of that protein source is actually utilized by your body. So, if consume 30grams of protein
from source A, how many of those grams are actually broken down and absorbed by your
body? The plain fact is that whey protein has the highest biological value of any protein
source you can possibly consume. It’s significantly higher than casein. And when you actually
look at casein individually, casein has a lower biological value than a lot of other
protein sources, including, you know, a lot of basic whole food protein sources like beef,
milk and eggs for example. So, in terms of biological value, whey is the clear winner
in that — in that case. And when we’re talking about amino acid profile, basically proteins
are made up of individual components called, “Amino acids.” And some of those amino acids
are more valuable than others when it comes to supporting muscle growth and recovery.
There’s about 22 individual amino acids, eight of which are essential, which means that your
body can’t produce them on its own. And again, whey protein wins in this category as well.
Whey protein actually has the best amino acid profile, not just in comparison to casein,
but in comparison to any whole food protein source that you can consume. And this is largely
due to its high branched-chain amino acid content, which are the amino acids L-Leucine,
L-Valine and L-Isoleucine, particularly L-Leucine which is considered the most anabolic amino
acid there is. A typical, you know, 30gram serving of whey protein isolate, will generally
deliver about 4grams to 5grams of branched-chain amino acid, which is going to help you, you
know, support muscle growth and recovery more effectively than other protein sources. So,
that’s really all there is to it, you know. Again, digestion rate is irrelevant. And given
that the digestion rate is irrelevant, all you really left with is to look at the individual
quality of the protein source itself. And whey protein is a much higher quality source
of protein than casein is. Better biological value, better amino acid profile, not to mention
that whey protein is also a better tasting, mix is easier and it’s a lot more flexible.
I don’t know if you’re ever tried a pure casein powder, but you’ll notice that it’s very,
very thick, and it’s very difficult to combine other things with it like, you know, a food,
oatmeal or whatever else you’re putting in your shakes. If you’re trying to make a pure
casein smoothie, you know, good luck, it’s — it’s pretty hard to do without turning
it into like a really thick kind of sludge almost. Whereas, whey protein is a lot more
flexible in that — in that respect. If you’re looking for a top quality protein powder to
include in your muscle building diet, make sure to check out IsoM3, that’s the whey protein
that we make here at Elite Impact Labs. You know, again, we don’t bother with casein powders.
We don’t even bother with, you know, the four-stage sustained release protein powders that you
hear about. This is just hype. There’s, you know, sometimes you see proteins that give
you whey, and casein, and egg, and milk protein and it seems like a, you know, like a good
idea. But again, in reality because digestion rate is relevant, all you want to focus on
is getting the highest quality protein you can possibly get. And whey protein is the
highest quality you can get. So, in terms of protein powder, that’s what you want to
focus on. IsoM3 is derived from 100% micro-filtered, ultra-filtered whey protein isolate. There’s
only 1gram of carbs, no fat, low sodium, no cholesterol, no lactose, and naturally sweetened
with stevia. So that’s a really high quality of protein. You can check that out by clicking

  1. I wish your IsoM3 was not sweetened with stevia or anything for that matter. I don't really like the taste of stevia. Besides, when I use whey, I combined it with things that are already sweet, like fruit/juice. Sometimes just I don't want my meal replacements drinks to be sweet.

  2. Very informative, thought I have one quite important question that I think everyone would like to know: What's your opinion on Soy Protein? I could really make use of your advice.

  3. I eat 1-2x a day usually right after my workouts. I used to tell people this and they literally accused me of lying, since I am 184 lbs at 9% bodyfat.

    They people are so dumb, they believe what people tell them and very easily coerced. They used to tell me, oh but your body can only digest 30g of protein at once…how are you able to maintain all your muscle and all that. Think about it if protein digests at 8-10 g an hour (truth) and I eat 170 grams of protein in 1 meal…do the math.

  4. you are doing the right thing…you should consume the majority of your food after your workout, and you only need to eat once or twice a day. i do the same thing, right after my workout i eat a big high protein meal with moderate carbs. the results have been amazing, im cut fat and still gain muscle,

  5. it seems he read book "the protein book" by lyle mcdonald :). buy this book and will know everything about protein.

  6. Amino acid pills are useless – it's basically just protein in compressed tablet form and way more expensive per gram.

  7. I haven't had a single order sent back from customs and have shipped quite a large number of orders there.

  8. Lets say me in my case i bought gold standard ON casein protien for after my morning cardio workout at 6:30 so that i wont really get hungry during work (7:30 am-3:00 pm) and i only eat some fruit and water during my work time, so i can keep protien in me and not feel the need for another shake again during that time, is that good in your sense? what would you reccomend.

  9. It would be a shame if you did not shed pounds when other people lose weight so easily using Fat Blast Lifestyle (go google it).

  10. It would be a shame if you did not get ripped when these other people accomplish it so easily with MAD Muscle Ripper (Google it).

  11. The only debates I hear on this is that casein kills people by feeding cancer cells… Anyone ever hear that? I don't know what to think of it

  12. Hey Sean, Can you use the two of them together?? Ex. Whey isolate as "breakfast" on non-training days and as a "post-workout" on training days. Then consistently use the Casein before bed on all days? Im just starting out and I real want to help my body at the absolute best times. The digestion rate doesn't really matter to me either. I don't mind only using Whey!!

  13. I'm glad I researched this before hauling off and buying casein. This is the 6th video I've found that says slow digestion is a bunch of crap and that quality is what matters.

  14. if you dudes desire to get ripped quicker without wasting a single another minute in the gym, then you should keep an eye on this video COOK46.COM

    The last thing we wanted was for the Machiguenga to be sad again. Sadness appeared to bring out their violence.

  15. The key to building muscle fast is a structured diet, exercise and getting proper rest. Your body needs an increase in calories, proper muscle stimulus and recovery time for optimal growth. Here are some tips:
    1. Start Weight Lifting – Learn proper techniques
    2. Do Calisthenics or Compound Exercises
    3. Eat Whole Foods
    4. Get 8 hours of sleep
    5. Eat More Frequently
    6. Drink Lots of Water

  17. Hi Sean, will it be useful to drink casein before you sleep to provide the nutrition and not starve the muscles?

  18. Hey bro, thanks for the video! Didn't have the option to use whey since my brother bought wrong protien but this was extremely helpful and WHEY is my preferred option indeed!

  19. I do not know if you are reading this but i wanted to say something to you: those are things that I knew for quite some time, but I did not found any specific science anywhere to prove that(only general things like BV, PCDAAS tables), so I couldnt say that out loud because I had now "power" in my arguments. Now I know those things better so I can use them in debates which are very pleasant for me. Thank you for all those informations. You really helped me. 😉

  20. Hi. I am always drinking casein before sleeping. After seeing your video, is it okay just to drink whey before sleeping?

  21. So…. I have heard that you should consume protein as fast as you can after your training. Is this true? Since it takes a hour to digest 3g of protein? Should I take protein before training then?

  22. Hey Sean,

    After seeing this video, can i ask your opinion on Select Protein. I'm curious about what you think of this product and what they have to say about the their mix of whey + casein.


  23. Just wanna say Sean, you're always my go to for advice on fitness/bodybuilding etc topics

    You're humble, straight to the point, detailed and helpful

    Thank you so much, carry on posting your awesome content 🙂

  24. Hi hubby. 😊. I bought casein today. Just to give it a try. Because I work out at night and won't hurt to try something different right? And I'm thinking of purchasing aminocore bcaa as a pre and during workout drink. What you think of this combo.?

  25. Hi ! i'm 16 Years Old And I'm Thinking to buy a supplement ! i'm 1.79 and 62kg what should i take ??  " i don't really care about time 🙂 " please answer me and thanks so much 🙂

  26. I am currently cutting and am in a caloric deficit. I need protein supplements simply because i cannot get my protein needs from whole foods. Would Casein help me feel full? but still give me the protein i need in a day?

  27. I jumped subed, your content is great. you tell us beginners the truth, other then all these liers on the internet. keep it up bro, your a role model.

  28. then, if it takes one hour to absorb 8 grams of whey protein, its better to take a scoop right before work out, so you train for 1 or 2 hours, go back home and eat real food, and ur covered the whole time, cuz one scoop is 24g… idk if thats really how it works tho

  29. But casein protein helps fight muscle degradation, which is better for building muscle in the long run isn't it? And slower digestion rates do matter especially if you're cutting or trying to lose weight because they stay in your system longer and you don't get hungry as fast as if you were to take whey. I will say though that whey protein is much better for bulking because it gives you a quicker source of protein that digests faster and makes you hungry faster so you can eat your next meal. In my opinion, protein brands that blend both casein and whey into their powder are the best, because you not only get the short term effects of whey, but also the long term effects of casein.

  30. Whey gives me constipation concentrate or isolate..Casein is good for this common or normal 🤔 any thoughts 💭 why this happens to me

  31. The majority of people say whey protein is much superior than Casein. But I get much more gains using Casein protein. So my advise is try both proteins to figure out wich one works better for you.
