difference b/t casein and whey protein?

[mademan80]

anybody know the difference b/t the two and the benefits of both?

[tbombz]

casein takes a long time to digest. whey digest very quickly.


for example = drink 60g of whey... youll get 60 g of protein released into your bloodstream over the next hour.  but drink 60g of casein, and youll get something like 6 grams every hour for the next ten hours.   (these are rough estimates and the actual numbers could vary a bit)

what "isolates" very "regular" whey? any differences in digestion time?

I've noticed that if I ingest 50g of whey + 50g of dextrose I'm pumped and full like a pornocock

i think there is a small difference in the time it takes to digest an isolate vs a concentrate, but i doubt its signifcant.


 i believe that unless your isolate has been "isolated" under the right conditions (cold), then whey loses its "biological activity" (not sure exactly what that means in this case)

So which is better?  To eat a ton of whey, or a ton of Casein?  I would think that the Casein would be better because it is digested slower, and gives you a more sustained release of protein into your bloodstream.

it depends.. equal amount of protein, probably very similar results, as long as both are used sensibly ( a decent amount spread through several meals)... whey probably a bit better for putting on muscle, casein probably a bit better for losing fat

i read an article about cutting wieght and your right tbomz if your trying to cut fat casein would be the best bet but it also stated that you need to use a good whey as well not to be totally impartial to one...and the article mentioned that casein would be a good bedtime protein since it digests slower than whey

[elite_lifter]

Casein b4 bed or during long periods w/o protein intake

Whey at all other times during the day

Wrong.

Remember this rule - you need fast protein and slow carbs.

Whey protein is better during the day (and especially post workout) as it gets into your system faster and prevents catabolism. You should be ingesting fast digesting protein (such as whey isolate) into your body at least every three hours to prevent catabolism and maintain anabolism (two hours for very skinny ectomorphs).

The only time you should ingest casein is just before bedtime - the time-released nature of the protein will prevent catabolism while you sleep and allows the body to recover at the same time over an extended period.

Casein isn't as good as whey isolate because the amino acid ratio isn't as good or diverse. Whey is a "perfect" protein source as it contains 100% of all essential amino acids and 90% of all powder ingested gets absorbed by the body compared to only about 70% for casein. In other words, for every 10 grams of caein you take in, the body will only use 7 grams for muscle building purposes. The rest will get wasted.

The complete opposite is tru for carbs - you need slow-releasing carbs (complex carbs) as the rapid insulin spike you get from fast-released carbs (simple carbs) isn't good for the body. Slow releasing carbs are less likely to promote fat gain.

Hope this helps

thanx big j very informative...

So can you please give some examples of slow-releasing carbs ?

beans, fruits, veggies, oats, whole grains...

back to the origin of this thread; last trueprotein.com order I went "fuck it" and orderered 50/50 mix of whey/casein...

let's see what comes out of it but so far my whole body feels full like a rising cock.

If you want to slow the digestion of the whey just use some natural PB with your shake.

  Casein and whey(lactaulbumin) are both milk proteins. Whey occurs in much lower quantities as a fraction of total milk protein, and thus is much more expensive. Whey has high bioavailability and gets into your bloodstream quickly, whilst casein takes longer to digest. Whey also has a higher BV than casein. Whey varies dramatically in it's biovailability depending on the process used to extract it. The processes of microfiltration and ion exchange result in less damage to the amino acid structure of whey, and thus is a protein with a higher biological value. Whey occurs in a form called peptides, which essentially means that it comes in short chains of bounded amino acids. Different peptides have different effects on the body. For instance, beta-immonoglobulin has potent immuno stimulating properties. Lactoferrin increases the utilization of calciferol. In general, it is stated that whey is better to stimulate growth after training due to it's quick passage through the GI, whilst casein is better to take before bed because it's slow digestion provides amino acids to the body during the long hours of sleep when you are getting no food. In my opinion, this is just a myth, and whey is superior to casein in every way.

IMHO, the best protein you can make is either a 50/50 mix of Milk & Whole Egg protein, or you throw in some calcium caseinate with it.
Fuck the "Whey is holier than thou" attitude.
