got blood work back (posted), certain levels are elevated. doc says its pre-workout?

[xplicid01]

Just got my lab results, few things came back higher than the doc would like: Urea Nitrogen (bun), bun/creatinine ratio, alkaline phosphatase, ast and RDW (doc said to ignore RDW). In talking it over with the Doc, he said there was nothing to be super worried about but wanted to pin down what could be causing the increase. I mentioned I had a very high protein diet and that could be the cause. He than asked what supplements I was taking so I told him: multi, fish oil, protein, creatine, BCAAs and caffeinated pre-workout. He than went on to say he has seen on numerous occasions that these preworkouts can increase some liver enzymes and suggested I stop taking it. This is like asking a happily married man to get a divorce from his wife, I LOVE c4. I really dont want to stop and have read that bun and creatinine are commonly out of whack with bbers.

in looking at the lab results, is there anything I should be worried enough about to stop taking the pre workout?

I appreciate the help guys, its kind of discouraging to lead such a health lifestyle and find out you are not in tip top shape. One thing to note is i was dieting HARD, I was told by the doc that might be why my test levels are not as high as they had been in the past but he didnt think it could cause issues with the other aspects. My Test was 546 when in the past it had been 690

As always, consulting with the doctor is best for result interpretation.

That said, I disagree on the assessment.

AST and ALK get elevated substantially for up to a week after heavy resistance training: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2291230/ -- so if you happened to have lifted recently, the elevated result on that parameter is not terribly meaningful. You'd need to abstain from resistance training for a week before the blood draw to have any conclusion there and, given that the elevation above reference range isn't huge to begin with, I wouldn't even worry about it.

Your hematocrit isn't super high, but I'd still say that the ever-so-slight BUN elevation is more likely due to dehydration than a preworkout supplement.

dehydration

I had a similar panel once (in regards to the readings in question). Turned out I was dehydrated. Easy to do with high-protein diets, hard training, and supplementation.

OP, what's your daily water intake like? Honestly?

[ManintheStreet]

Upping your water intake will help a lot. If not this may help: If you take creatine everyday, limit it to just on workout days. Also C4 has creatine nitrate this will add to your total creatinine levels I believe. I am unsure of the ratio that creatine nitrate etc vs creatine mono but i guess work it out and then restrict yourself to get the equivalent of 5g a day of creatine mono on workout days your muscles are already saturated save yourself some coin.

Upping your water intake will only help with the BUN here. Regardless, your numbers at not that bad. Liver enzymes can be elevated post training. How long was it since you worked out and had blood work.

i'd of got him to specify what exactly in a pre workout could cause it

given the fairly varied ingredients... seems far to vague

I wouldn't worry about the AST/Alk Phos

The BUN:Cr being greater than 20 indicates that you're dehydrated.

I would recommend following your doctors instructions. Either that or seek a second opinion from another qualified doctor (not the BB.com forums)
