"human dietary boron consumption in the US is in the range of 1-2 mg." "In

postmenopausal women...a daily dietary intake of 3.23 mg boron for 49 d...decreased

fasting serum glucose concentrations ....approximately 6%". "the glucose tolerance test

of 8 subjects with initially impaired glucose tolerance ...improved significantly during

chromium supplementation. Less than 20 mcg chromium/day was sufficient to prevent

impaired glucose tolerance..." "studies using lower doses [of fluoride]...combined with

calcium supplementation have shown lower vertebral and peripheral fracture rates-

vitamin D and boron metabolism are closely linked. Important for bones
