Effect of dietary boron on mineral, estrogen, and testosterone metabolism in postmenopausal women
Type of spiritual experience
NOT boron supplements, but a diet rich in boron, note.
A description of the experience
FASEB J. 1987 Nov;1(5):394-7. Effect of dietary boron on mineral, estrogen, and testosterone metabolism in postmenopausal women. Nielsen FH1, Hunt CD, Mullen LM, Hunt JR.
A study was done to examine the effects of aluminum, magnesium, and boron on major mineral metabolism in postmenopausal women.
This communication describes some of the effects of dietary boron on 12 women between the ages of 48 and 82 housed in a metabolic unit.
A boron supplement of 3 mg/day markedly affected several indices of mineral metabolism of seven women consuming a low-magnesium diet and five women consuming a diet adequate in magnesium; the women had consumed a conventional diet supplying about 0.25 mg boron/day for 119 days.
Boron supplementation markedly reduced the urinary excretion of calcium and magnesium; the depression seemed more marked when dietary magnesium was low.
Boron supplementation depressed the urinary excretion of phosphorus by the low-magnesium, but not by the adequate-magnesium, women.
Boron supplementation markedly elevated the serum concentrations of 17 beta-estradiol and testosterone; the elevation seemed more marked when dietary magnesium was low.
Neither high dietary aluminum (1000 mg/day) nor an interaction between boron and aluminum affected the variables presented.
The findings suggest that supplementation of a low-boron diet with an amount of boron commonly found in diets high in fruits and vegetables induces changes in postmenopausal women consistent with the prevention of calcium loss and bone demineralization.
