But what did happen is my bloodwork came back after a Dr visit with elevated Creatinine levels which concerned my Dr. I've since stopped the creatine supplement, and have an upcoming Dr appt to follow up

The supplement I used was LIVEGOOD Creatine+HMB which I mixed with my protein shake every morning and I used the amount recommended by the mfg.

Interesting. It sounds like a bunch of medical professionals don't know about creatine harmlessly elevating creatinine levels.

Additional considerations

Your serum (blood) creatinine level is a very effective test for checking your kidney health. However, there may be other factors that can cause higher or lower creatinine levels in your blood that are not related to your kidney health. In other words, your actual kidney function (eGFR level) may be higher or lower than what is reported in your lab results.

Some factors that can lead to higher creatinine levels (making your eGFR level appear lower than it might really be) include:

Eating large amounts of cooked meats
Taking creatine supplements
Recent high intensity exercise
High muscle mass (very muscular body frame, bodybuilder)
Taking medications such as cimetidine, cobicistat, dolutegravir, fenofibrate, ritonavir, or trimethoprim
