Creatine usage

Maybe coincidence ?
Journal of Renal Nutrition have meta analysis of medical studies and found there to be no correlation-

It’s absolutely fine if your kidneys are fully operational. It’s not if you have poor kidney function. EGFR over 90 and crack on, lower than that, don’t take.

When i used to take it i had blood tests done at my GP. He commented on the high levels of creatinine in my results
I stopped taking it and the levels returned to normal.

Realise this is an old post and apologies for bumping. From what I understand though - and I'm not claiming to be an expert - having high creatinine levels is expected when taking creatine but doesn't mean there is any impaired kidney function. The body produces creatine naturally but it is filtered through your kidneys, converted into creatinine and pissed out. Whereas creatine tablets/powder divert and store more of it in your muscles instead to provide more energy, so you will naturally have higher creatinine levels from the creatine that is stored. It doesn't mean your kidneys aren't working, it means you've got more creatine stored in your body.

My wife has a kidney transplant due to renal failure. She has creatinine levels tested every few months as this is the main way of checking kidney function (if the kidney wasn't working it wouldn't filter her natural creatine and therefore higher creatinine). If she took creatine her creatinine levels would elevate further which would render the creatinine tests useless and there's be no way of knowing whether her kidney was functioning OK. But unless you're concerned you have kidney disease there's no reason to worry about the higher creatinine levels when taking creatine.

That's not entirely correct. Having high creatinine levels is not expected when taking creatine (if taking recommended doses). Having slightly higher levels than you would otherwise have is to be expected, but having high levels that are a cause for concern would indicate some other underlying issues. If your kidney function is not where it should be then its sensible to avoid creatine, but more generally the benefits of creatine are manifold and have been borne out in an enormous amount of studies.

Hope your missus has good health.

I take creatine every day and only stop if I'm going on holiday or away with work (because I couldn't be arsed taking creatine with me). The only issue I have is I find I piss more often.
