Default Egg Protein Supplement Question

I was wondering if anyone had some info on the usefulness of egg protein supplements. In particular, their bioavailibility. There is evidence that egg whites need to be fully cooked or they have very poor absorption.

I know that egg protein supplements are pasteurized but that's not the same as cooked, is it?

Any info would be greatly appreciated.

Scientific Description
Egg White Protein is extracted from pure egg whites then processed into powder form. It yields a higher protein ratio than liquid egg whites. Egg Whites provide an excellent source of amino acids and are high in the sulfur producing amino acid which is crucial in anabolic hormone production. Has a PER of 3.9 and a biological value of 88, making it a good choice for muscle mass gains. The amino acid level is not as high as the whey's, but egg beats out soy and caseinate for usability.

Typical Amino Acid Profile (g / 100 g )
Alanine 4.6
Arginine 4.4
Aspartic Acid 4.4
Cystine 2.1
Glutamine 10
Proline 3.1
Glycine 2.8
Hisdine 1.8
Isoleucine 4.5
Leiucine 6.8
Lysine 5.5
Serine 5.5
Threonine 3.6
Trypto 0.9
Tyrosine 3.1
Valine 5.1
Meth 2.7

I personally think egg is best taken before bed since it's the slowest digesting. If I have enough cash from time to time I usually get optimum nutrition's brand. It's more expensive than whey, of course. I looked at Pro Complex, but it's a mixture of egg and whey.

What I felt was optimal was to have my regular postworkout shake of whey, then a half hour later drinking an egg protein shake. Before bed, if I don't feel like eating cottage cheese, I'd have a second egg shake. At least this way you'll conserve it and make it last since it's expensive.

Thank you, 0311. That explains it. It being an extraction. I don't know why I couldn't find this info. I was under the impression that it was just freeze dried egg whites or something. There is something I forget the name of in egg whites that limits their absorption unless heat treated. No such problem is the protein is extracted and somewhat more pure, I guess.

And, yes, that is exactly what I was planning to do with it if I were to buy some. Use it before bed or as a follow up after my pwo shake.

Thanx a lot

Yeah, I would recommend doing both so you'll have a steady release of blood aminos. However, if you get really cheap like me, you'll just substitute that second PWO shake for another whey but mixed in a glass of skim milk. By sipping it until your next meal you'll be good to go.

I'm revisting this question because in looking at ON's description of there egg product, there is no mention made of it being an extract of egg whites. In fact, all they say is that they separate the whites from the yolks (nothing magical about that) and pasteurize and "spray dry" them.

Pasteurized eggs are still considered raw eggs, even though they may be free from salmonella. Raw egg whites do not absorb well at all and they will also leach biotin from your body.

If I were to buy any I think I would go with the Protein Factory product, where 0311 took the info from, since they actually make claims about the bioavailibility and mention that the protein is extracted from the whites. I'm not sure this applies to all egg protein products.

But again, I don't really know and am just using the info I have. If anyone knows something I am missing, then please let me know.

I recommend going to the lab (protein factory) and making a mixture of casein and egg protein. For what you want (before bed), this would be the best idea. Different proteins digesting at different rates which is best for breakfast and before bed.

Sounds good. The price at Protein Factory is actually pretty nice.
