I was searching for some information on diet and Osteoporosis for Mrs. G and found the attached study regarding boron.
I thought some of you might be interested.
The difference between a low boron and high boron diet is a greater retention of calcium and an increase circulation of of testosterone and 17B-estradiol.
The study population was of post menopausal women (48-84 IIRC)
But the study population was small.
The difference between a low boron diet and a high boron diet seems to be about x2 for the hormone profile and about 50% additional calcium retention.
