Increased creatinine levels due to creatine or high meat intake are not harmful and may warrant cystatin C testing for kidney function assessment.

“Not particularly. You could look at your uh creatinine, which will be um a little bit falsely elevated. So creatinine is a measure of kidney function, and that will elevate with creatine supplementation. Um, I wouldn't necessarily use it to tell whether you're at adequate dosing or not because I think that like it can be confounded by other things like hydration or kidney function.”

“but the creatinine is a measure of kidney function but it's not a perfect measure of kidney function cratan comes from the breakdown of muscle creatine and in people who are extremely muscular you can see creatine that is falsely elevated and so if you are also eating a lot of protein your creatinine may be slightly higher”

“the more creatine in your muscles more creatine in your blood if you're supplementing with creatine you may have more creatinine in your blood okay”

“those of us who are particularly muscular or eating significant amounts of creatine whether by supplementation or meat may see bumps and serum creatinine that don't reflect any decline in kidney function”

“your creatinine which is a breakdown product of creatine in the muscles will be elevated or may be elevated above what you've seen in the past this doesn't mean that your kidneys are failing though elevated creatinine can in some individuals be linked to kidney issues if you are supplementing with creatine or eating a lot of meat the chances that this is related to your kidneys are very low the chances it's related to more production of creatinine from creatine breakdown in your muscles are much higher”

“when you go to your doctor your creatinine which is a breakdown product of creatine in the muscles will be elevated or may be elevated above what you've seen in the past this doesn't mean that your kidneys are failing though elevated creatinine can in some individuals be linked to kidney issues if you are supplementing with creatine or eating a lot of meat the chances that this is related to your kidneys are very low the chances it's related to to more production of creatinine from creatine breakdown in your muscles are much higher”

“my creatinine which is a measure of kidney function is slightly elevated at 1.3 this is important to note for anyone who is supplementing with creatine creatine is a compound that your body makes but many many many studies on the order of three to 400 studies perhaps with creatine show that it's beneficial to have usually a little more than your body is making”

“when you supplement with creatine your creatinine will go up creatinine is simply a proxy for kidney function and in quote normal individuals who are not supplementing with creatine eating a lot of meat which also contains creatine or individuals who are not overly muscular a creatinine between as the lab says here 7 and 1.2 usually says your kidneys are functioning quite well in an individual who is not doing any of those things isn't super muscular and elevated creatinine may suggest that your kidneys are not filtering that creatinine breakdown product of creatine out but in those of us eating meat in those of us who have more muscles and those of us supplementing with creatine it just means that you're making more creatinine from creatine and creatinine itself is not harmful”

“The only asterisk with creatine is that sometimes your creatinine which is a breakdown product of creatine which is not harmful but it is how we measure kidney function may go up so if you're eating creatine or you're eating a lot of meat in your diet and your creatinine creeps up ask your doctor for a cystatin c”
