Brief summary

Within the context of the proposed research study, the effect of soy isoflavonoid supplements on the quality of life and coagulation of menopausal women. It has been observed that menopause, as a physiological process, is associated with alterations in the physical, mental and sexual quality of life, making the use of hormone replacement therapy necessary; however, hormone therapy is associated with hypercoagulability, since it has been seen that women have higher levels of thrombogenic microvesicles such as: platelets with a greater probability of causing blood clotting were more likely to present a greater amount of white matter hyperintensities, which appear in the MRI scan.

Detailed description

The following study is aimed at clarifying the effects of soy isoflavonate supplements on the quality of life and markers of hypercoagulability in menopausal women. The reasons for conducting this research arise from the concern of minimizing side effects such as hypercoagulation caused by hormone replacement therapy, which is intended to be replaced with soy isoflavonates to evaluate its efficacy.

Interventions

Masking
DOUBLE (Subject, Investigator)

Masking description

To eliminate researcher bias, a third research participant will place the capsules containing the soy isoflavonate in one bottle and the placebo in another bottle. The bottles will be labeled as group A and group B, but the researchers will not know which is in which group, to ensure that the study intervention and the control/placebo are as indistinguishable as possible to the participants.
