I LOVE Maca. I have been taking it for probably over a year for energy. I am 45 and have a high energy physical job. I do not take it every day but most days, probably around 4 x 500mg caps each time, sometimes more or less. My mood is generally happy, light, up beat and sharp. Recently, in the past 3 months I have noticed increased breast tenderness around the time of ovulation, to the point that if someone hugs me I can shoot through the roof (metaphorically). My breasts have also grown a cup size, and my periods have been acting strangely, spotting a few days before full flow is due. I generally feel great though and I love feeling fuller breasts as they seemed to shrink during breast feeeding my child 8 years ago.
For ref I use organic 'Herbs America' maca magic caps.
Just posting wondering what you other ladies are going through. Hope this helps.
