i use melatonin before CT and PET scans to help block some of the high radiation these imaging scans produce. Here is an IMA article showcasing much more.
As far as my claim above that it helps with imaging, here is what Ai wrote when I asked:
Human Study on DNA ProtectionA double-blind, placebo-controlled human study found that a single 100 mg dose of melatonin taken one hour before a CT scan resulted in a significant reduction in DNA double-strand breaks in peripheral blood lymphocytes compared to controls. The effect was measured as a reduced number of Ξ³H2AX foci, a biomarker for DNA breakage
