High b12 levels and 1 kidney

[Shookjohansen]

I got blood work back that states everything is pretty much normal.  I have 1 kidney and my creatinine is .75 which is great.  That means my gfr is 105. BUN was 6 which is slightly low but good.  The one thing that came back high was my b12 results.  Normal ranges are 200-1100 and mine are 1590.  He did not seem concerned but is this normal with one kidney? Maybe I can't filter as effectively? I overly take a lot do b vitamins and I am a vegetarian that is gluten free.

Ok, so you do not take excess vitamin B complex. If you take any supplements at all, avoid them. And you could repeat the test.

Hello and hope you are doing well.

B complex vitamins are water soluble and when in excess are easily excreted by the kidneys. So, the raised levels may not be due to a single kidney, its more likely to be due to consuming excess. You could cut down on the supplements and repeat the test.

Hope this helped and do keep us posted.

That should say I do NOT overly take a lot of b vitamins
