Bone Growth and Maintenance
Scientists have known for many years that boron is essential for healthy bones. In 1985, the US Department of Agriculture (USDA) conducted an experiment in which postmenopausal women (n = 12) who had been put on a low-boron diet (0.25 mg/d for 119 d) were supplemented with 3 mg/d of boron during two 28-day trials. In one trial, magnesium intake was low; in the other, magnesium intake was adequate. With boron supplementation, the women’s daily urinary excretion of calcium was reduced by 44%. The reduction in calcium loss resulting from boron supplementation was 52 mg/d when the women were low in magnesium and 22 mg/d when magnesium levels were adequate.1
Since 1990, boron has been shown to significantly improve wound healing. Application of a 3% boric acid solution to deep wounds reduced the time required in intensive care by two-thirds.
Regulation of Sex Hormones
Increased levels of sex steroids have been demonstrated in both men and women after boron supplementation.1,20 In 1987, Nielsen et al1 reported that dietary boron repletion in postmenopausal women (n = 13), who were previously on a low-boron diet, significantly increased their serum estradiol (E2) and testosterone levels, particularly for those women whose dietary intake of magnesium was low. In women on a low-magnesium diet, E2 almost doubled, increasing from an average of 21.1 pg/mL to 41.4 pg/mL.
[Men] Testosterone more than doubled, rising from an average of 0.31 ng/mL to 0.83 ng/mL.
Prevention of Vitamin-D Deficiency
Boron has been shown to increase serum levels of 25-hydroxyvitamin D3 (25[OH]D3) in animal studies4,24 and of vitamin D–deficient individuals in human studies.25,26
Magnesium Absorption
Boron significantly improves magnesium absorption and deposition in bone, yet another beneficial effect of boron’s inhibition of 17β-estradiol degradation.
Anti-inflammatory Effects in Osteoarthritis
Epidemiological evidence, case reports, and controlled animal and human studies have provided evidence for the use of boron as a safe and effective treatment for osteoarthritis (OA).52-54 Examining the relationship between boron administration and OA prevalence around the world, researchers discovered that in areas where boron intake is greater than or equal to 1 mg/d, the estimated incidence of arthritis ranges from 20% to 70%. In contrast, in areas where boron intake is usually 3 to 10 mg/d, estimated incidence of arthritis ranges from 0% to 10%.
Anticancer Effects
An increasing number of papers have indicated that boron possesses anticarcinogenic properties. Boron-rich diets and regions where the soil and water are rich in boron correlate with lower risks of several types of cancer, including prostate, breast, cervical, and lung cancers. Boron-enriched diets have been found to result in significant decreases in risk for prostate and cervical cancer and to decrease risk of lung cancer in smoking women.
FYI: The abstract says “Thus, the 3 percent boric acid solution may be considered an efficient alternative in the treatment of deep wounds with loss of substance, but it is delicate to handle because of toxicity.”
Toxicity? The LDL50 (how much it takes to kill 50% of the test animals which are typically rodents) for boric acid is 3450 mg/kg. For comparison, the LD50 for aspirin is 200 mg/kg.
