Guest guest Posted December 5, 2005 Report Share Posted December 5, 2005 , I'm not sure I can give you an exact answer, but I can give you some background. This comes from the vitalady website (vitalady.com). Her web site states that the body is only able to absorb 30 grams of protein at one time. I was getting a lot of questions from my patients so I actually e-mailed the vitalady last week. She told me that number comes from the protein manufactures. Not sure that's the most accurate source of info. I have to say, in all my years of education, I've never learned that there was a maximium number of grams of protein the body can absorb at one time. This topic has come up before on this web site. I'd also be curious to hear feedback from others.

Guest guest Posted December 5, 2005 Report Share Posted December 5, 2005 I also spoke to a representative from a supplement protein manufacturer (the name escapes me at the moment), and he stated, which makes sense, that it is weight dependent. An approximate calculation is patient's weight in pounds divided by 10 and then multiply by 1.5. Therefore, a 350# individual could safely absorb ~50g protein (350/10 X 1.5 = 52.5). Other factors come into place, such as an increased need for protein post-op, consuming protein after a weight work-out, etc. Kate Alie, M.S., R.D., L.D.

Guest guest Posted July 10, 2006 Report Share Posted July 10, 2006 When I looked into that before what I came up with, and sorry I don't still have the references, was that each person was different in what they could absorb. So they might absorb alot at once and then again maybe not. It also seemed to vary from day to day as well. So I always recommended that they spread their intake throughout the day rather than trying to load up on their protein all at one time. J.

Guest guest Posted July 11, 2006 Report Share Posted July 11, 2006 I have heard similar information over the years (~3 oz. protein or ~21 gms) is what can be utilized in one sitting.

Guest guest Posted November 28, 2006 Report Share Posted November 28, 2006 I have many patients who use 1.5-2.5 scoops of protein powder when making shakes, in order to meet their protein goals during the day (sometimes this gives them 50-60 g/protein at once). From what I've researched, I haven't found anything that says the body can only absorb a certain amount at once. Anyone know of any research articles that say different? Thanks!

Guest guest Posted November 28, 2006 Report Share Posted November 28, 2006 , If you do a Google search, you'll come up with hundreds of sites-- some on nutrition, some on body building, some from protein supplement manufacturers. You'll also find some interesting discussions about why the 30 g max is a myth.
