[polymorphis]

I know too well that translating anecdotal information or even laboratory results into practice can be quite difficult, but I can tell that since I begun to take 8 mg of astaxanthine a day, my libido went south so I returned to 4 mg a day.

But I may be just the strong responder to anything antiandrogenic and estrogenic. Few years ago I had a quite strong reaction to sage tea which does contain some phytoestrogenic compound, but it is hardly used for anything more that menopausal hot flushes

Anyway, thanks everyone for the great input!
