Zinc supplementation is popular with men including many on TRT . Those who have an MRI planned which includes the use of a contrast dye may wish to stop taking the zinc in advance of the exam.

Patients are told the dye is safe because the heavy metal Gadolinium is chelated and cleared from the body by the kidneys. Gd may become dissociated to its free form which then may then be deposited in the brain and / or elsewhere resulting in serious long term side effects. Transmetallation with Zn is postulated to be one cause of Gd accumulation in tissues.
If you are told that Gd dyes are 100% safe because they are eliminated shortly after the exam don't believe it. To get an accurate diagnosis, for that of a kidney mass for instance, you may not have a choice in refusing the dye. The risk should be properly disclosed and you may be able to mitigate somewhat by being off certain supplements in advance of the exam.
