My wife's favorite supplement

Posted by alloriginal on May 22, 2013

my wife was suffering from irregular, painful menstruation. One capsule per day seems to have cured it. She is delighted, and so am I! We've run out in the past, and the problems have returned, so we don't intend to ever run out again. I believe that nutritional supplements saved my life. I've tried a lot of products, and I know what works and what doesn't. My reviews are honest, straighforward, and based on my experience. Read my other reviews to quickly learn from my three decades of research and experimentation.
