A)    FEMALE HORMONAL HEALTH

Research suggests that boron supplementation significantly influences oestrogenic activity. One clinical trial involving postmenopausal women taking 3mg of boron per day demonstrated a substantial increase in 17 beta-oestradiol, the most active form of oestrogen. Although research currently appears to be lacking with respect an influence of supplementation on menopausal symptoms, there is evidence for an beneficial impact on calcium levels in the body.

B)    SKELETAL HEALTH AND BONE DENSITY

The skeletal system is likely to be a primary recipient of boron’s nutritional benefits. As mentioned, boron supplementation significantly elevates oestrogenic activity, which more than likely will have a positive influence on bone density in women. Particularly relevant to skeletal health are the data showing a 44% decrease in calcium excretion in postmenopausal women taking 3mg of boron per day. Aside from any effect on oestrogen, it has been suggested by scientists that boron may be needed in order for the kidneys to convert 25-cholecalciferol into the most active form of vitamin D (1,25-dyhydroxycholecalciferol). The latter is required in order for calcium to be absorbed in the intestines.

C)    JOINT HEALTH

Although the method of action has yet to be determined for certain, there are a couple of studies showing that boron supplementation has a beneficial effect on the joints in those with osteo, rheumatoid and juvenile forms of arthritis. The results of both studies indicated a measurable improvement in the vast majority of those receiving boron supplementation.
