It is difficult to determine the cause of your drug test without seeing the test results myself and without knowing the full details of your medical history. I encourage you to schedule an appointment with a primary care physician
to help sort out the details of your test.
Creatine phosphate works as a supplement booster because it provides extra phosphate molecules to replenish your body's energy stores. There is a theoretical concern that these supplements can cause heart, liver, and kidney damage, although clinical data are limited. Patients often experience stomach pain
, nausea, and diarrhea
. Additionally, people often gain weight due to fluid retention.
Urine tests typically measure creatinine, not creatine. Creatinine is a breakdown product of creatine phosphate that is typically filtered by your kidneys. Secretion by your kidneys can be increased by taking a creatine supplement. Both intrinsic and supplemented creatine phosphate must be broken down by your body, and it is unlikely that taking a supplement should decrease your level of urine creatinine. Increased fluid intake can lead to a decreased urine creatinine. Individuals often must collect urine over a 24-hour period, which allows urine creatinine to be corrected for total volume. I encourage you to raise these possibilities with the physicians performing the test.
