Why do I have amenorrhea when using Miositogyn GT?

Myositogyn GT is not a drug, but a dietary supplement that is supposed to supplement food with certain ingredients "contributing to the regulation of hormonal activity and involved in the processes of cell division". Among other things, Myo-inositol, which should not cause amenorrhea, but should contribute to the restoration of the normal menstrual cycle. It should be noted, however, that dietary supplements cannot be attributed the properties of treating diseases, but they should also not cause significant side effects if the recommended portions of the product are not exceeded. Unfortunately, I do not know what your health situation is and why you use the Miositogyn GT supplement. So it is difficult for me to judge what could potentially be the cause of your amenorrhea. If you are a sexually active person, then in the absence of a period, it is good to take a pregnancy test first.
