Question regarding nitrogen retention and urea nitrogen

[Jmuls]

I recently had blood work done and my plasma urea nitrogen came back elevated, at 28 mg/dl (normal range for this blood lab is considered 8-25 mg/dl). I've always just thought it was nothing to worry about, showing nothing more than the fact that I consume a high protein diet. Never the less, I began thinking about it more and realized that there might be something more to it. I've always understood that a positive nitrogen balance is achieved through the nitrogen intake being greater than the nitrogen output or removal. This would indicate, unless I'm missing something, that nitrogen retention is high, thus your not at risk for losing any muscle. We're hopefully in an anabolic state.

I guess what I'm wondering is, despite the fact that my daily protein intake is in excess of 350g per day, I'm beginning to wonder if that protein isn't sufficient enough to increase my nitrogen retention. My intake is high, but my output is higher than the norm, so I'm essentially pissing out a great deal of what I'm putting in.

You guys think that there's something to this or is a high plasma urea nitrogen reading just the norm for anyone who's consuming above the daily norm of .8g/kg/day, seen in average, sedentary individuals? Any thoughts would be appreciated. Thanks.

To keep this hsort, I think you are a little confused.......apples and oranges there you are speaking of.

So you're saying there's no correlation between an elevated plasma urea nitrogen and lack of nitrogen retention at the muscle cell?

To be honest, I began wondering whether with a product like LBAs that you recommend, if one would be able to have a lower urea nitrogen reading. Seeing the combo of glycine, arginine, proline, and hydroxyproline cause a high retention of nitrogen, and they're all present in high amounts with LBAs, then perhaps less protein would be getting excreted and more would be utilized.

Just my mind wondering about things is all.

Well

Your body utilizes more protein than you piss out. With that being said, if you are taking in a huge excess of protein, you will piss it out. If you notice, bbers that consume a high protein diet piss urine that bubbles up. Bubbles in urine=pissing out excess protein. This is why I'm not a big believer in consuming a massive amount of protein daily because it's very wasteful IMO.

The advice you give is totally wrong.......its is crazy actually....can you find anything that backs up what you just said?

I've had more than one doctor tell me that, but of course nobody's going to believe that because it's not on paper. People can believe w/e they want. Let me ask you this. Do you really think that taking in massive amounts of protein isn't wasteful? Fuck it, I'm going to delete my last post because I can not provide evidence on paper.
