Well,
there are no research results yet. However, I've heard a lot that BO is effective even foe people with hormonal imbalance. And I think the lack of research results is not because there is no effect, but because it is not a business that makes money.
I tried all the methods, but the one that worked was BO. Even I had an irregular cycle, but I came back regularly while taking BO!!!
BO certainly affects hormones, so I've never been tested since taking it.But I'm rather satisfied that the menstrual cycle has been able to return regularly since taking it.(From the beginning, the mentrual cycle tended to be very short and irregular).
When I first took it, there was "spotting", so I was afraid, worried, and embarrassed, but I kept taking it. After the second month, it seemed to improved.
I hope you only consider my opinion as a reference.
Because as a girl diagnosed with PCOS, I'm not only well aware of the anxiety about the disease, but also thinking we should be more careful about the NBE effect of having the disease should be more careful.
There are relatively few women who trey NBE even with PCOS, so the sample is small, too.
