at the moment i will have a 50g shake (2x25g servings) after training, i feel like i recover better comparing it to when i just had the one serving but Ive heard that your body can only absorb 20-30g of protein in one sitting, does anyone know if this is correct? Thanks :)

There is no set figure, but it all gets absorbed, any excess cals will be converted ultimately into (stored) energy but there is no amount to be absorbed at one sitting as your body is digesting and 'absorbing' all the time it doesn't stop doing it once you stop eating

Thanks for the advice, im a proper novice :)

There's no limit to absorption as stated by dirtyvest but most people tend I keep it around the 40/50g per meal mark.

And yes whey does digest faster, when mixed with water anyway. But it also depends what it is consumed with as whey with milk will be alot slower digesting due to the fats and casein in the milk, and if eaten at the same times as fats this will have the same effect.

But stand alone whey vs chicken/lamb/turkey etc then yes whey is alot faster at digesting. Obviously everyone is different but half an hour is a good guide for most wheys

No limit but presumably your meals are partially structured around providing a balance of nutrients and fall in line with approx daily targets and therefore it is logical to space these daily end targets out - this should in effect take care of the problem without the need for any extra concern :-)

My diet is hitting pretty much most of my nutritional needs at the moment, my meals are pretty consistant, i eat a balanced diet with 5 small meals a day and a couple of shakes. As I upped my training ive upped my intake, hense why ive doubled up on shake sizes as well as more actual food nutrients, A guy down the gym gave me the impression that your body cant use more than 30gs of protein in one go so larger serving shakes are a waste of time but it apperars that this is BS

Don't think it will ever die this one! Funnily enough often these will be the same guys that are getting more than 30g or protein in most of their normal solid meal, yet this dosn't worry them :)

one of the greater things to consider using a high protein diet for long durations is that it will put a certain degree of stress on the kidneys in and of itself. I personally rec it to be smaller and and more frequent servings spaced out as evenly as possible to reduce as much stress as I can while still consuming the same diet. I think anytime you binge with your servings you inevitably get less nutrient content due to the bodies digestive 'juices' being usurped by other material to be digested. I could be wrong as not everything comes down to common sense with this stuff. but it seems like I would be able to extract more from what I consume pd if I put it through my system in small bursts consistantly throughout the day, versus, say... one extra large omelette in the morning.

Most of the time I can do 40 / 50G without issue. Recently changed things around and before bed I'm having protein pancakes which work out around 70G of protein. www.ugm.org.uk

Im with Grendel
You really need to watch the excess protein route, it brings with it a few issues in regards Kidney ailments (kidney stones

)
If you take in too much protein your body just uses it for energy or excreates it.
I would recommend 30-40 gms per sitting depending on your LBMI (NOT BODYWEIGHT) , it may sound low to some but if you eat good quality protein its more than enough.

Regular protein feedings will probably cause greater stress on the kidneys than larger protein feedings.

The body dose not just allocate protein to energy production based on size of dose. Neither dose the body exrete proteins.. or at least you shouldn't be extreting very much protein if everything is working well!

Then you are talking about protein that is not digested and absorbed by the body (this actually means that it technically is not exreted). Yes excess may.

However this will depend on various factors and size of portion is only one. You'd have to have poor digestive health combined with very large serving of protein for this too occur significantly. With a healthy gut and large protein serving it will simply take longer for the protein to be digested. Off course there is an upper limit to what can be digseted effectively from one sitting. Again dependent on individual variation in gut health/efficiency and size, and for most will prob not be an issue.

Im pretty sure excrement is poo and that the word excrement is derived from the word excrete. I suppose technically we are both right if you use a dictionary. Doesnt really help the OP however, so thats me done.

What about the other main content of my post? The crux being that we can ingest pretty large amounts of protein in one sitting and you won't **** it out? That is helping the OP.

What exrete means or dosn't mean in a biological sense has nought to do with what we are dicussing... just the bit of pedant in me!
