I think Rick Kreider has done some studies with that when he looked at NCAA players.

But a lot of people don't take the myth was that it was dehydrating and we just don't see where did that myth come from?

I think what happened was in the inception of creating research, a lot of people were not drinking water or going through some practices like wrestling, wearing rubber suits, extreme hydration.

They happen to be taking creatine.

And then they said, well, I'm on creatine since it traps water.

biggest concern.

So we've looked at study after study and rest assured from a clinical perspective, creatine does not adversely affect renal, liver, or cardiovascular cells.

And we've given 11 grams a day in postmenopausal females to a population where their organs are under a little bit more stress and no adverse effects.

The theory here was that when creatine enters your muscle, when it gets metabolized, it's non-enzymatically metabolized to something called creatinine.

And those watching say, oh, wait a minute.

I just saw that my doctor checked that off.

And the reason they do that is creatinine is a byproduct.

It's supposed to be filtered by the kidneys.

So if you have high blood creatinine, that means your filtration rate in the kidneys is not working properly.

Think of your Brita water filter.

It's clogged up.

So unfortunately, when a lot of people go to their doctor, they don't say, hey, to the nephrologist or GP, I'm on creatine supplements because it's logical that if you're taking creatine, your creatinine might be acutely raised.

And then that causes a false positive.

Your estimated filtration rate is low.

So your doctor says, whatever you're taking, stop.
