Effect of dietary boron on mineral, estrogen, and testosterone metabolism in postmenopausal women
結論：Boron 3 mg/day markedly reduced urinary calcium and magnesium excretion (more pronounced in low-magnesium subjects) and significantly increased serum estradiol and testosterone. Authors framed results as 'consistent with the prevention of calcium loss and bone demineralization' — a mechanistic inference, NOT a measured BMD or fracture outcome.

Effects of boron supplementation on bone mineral density and dietary, blood, and urinary calcium, phosphorus, magnesium, and boron in female athletes
結論：Athletes showed a slight increase and sedentary controls a slight decrease in BMD over one year of boron supplementation; differences likely driven by physical activity rather than boron itself. Boron altered serum phosphorus/magnesium and urinary boron excretion across all subjects. Cannot isolate a boron effect on BMD without a placebo arm.

Comparative effects of daily and weekly boron supplementation on plasma steroid hormones and proinflammatory cytokines
結論：After 1 week of daily 10 mg boron, free testosterone increased, estradiol decreased, DHT/cortisol/vitamin D rose, and SHBG/hsCRP/TNF-alpha decreased. Findings concern hormone and inflammation surrogates in healthy men, not bone density or osteoporosis endpoints. n=8 with 1-week duration — pilot-grade only.

Nothing Boring About Boron
結論：Author argues boron is a beneficial trace mineral for 'bone growth and maintenance,' citing reduced urinary Ca/Mg excretion and elevated sex steroids from older studies (Nielsen-style work). Recommends supplementation for individuals with inadequate fruit/vegetable intake or at risk for bone-related conditions. Narrative-style with no quantitative pooling; published in Integrative Medicine (Encinitas) — a CAM-leaning journal.

Pivotal role of boron supplementation on bone health: A narrative review
結論：Authors conclude that 3 mg/day boron (alone or with other nutrients) supports BMD maintenance and is safe under EFSA's 10 mg/day upper level. This is a NARRATIVE review (no formal meta-analysis, no GRADE), drawing largely on the same older small studies and animal data; clinical-grade BMD or fracture RCTs in osteoporotic patients remain absent.

Because the FNB has not established an RDA or AI for boron, boron does not have a DV. 來源↗

The Panel concludes that a cause and effect relationship has not been established between the dietary intake of boron and maintenance of normal bone, normal testosterone concentrations in plasma, or maintenance of joint function. Tolerable Upper Intake Level for boron in adults: 10 mg/day (as boric acid equivalents). 來源↗

Although boron is not classified as an essential nutrient for humans, it might have beneficial effects on bone formation and maintenance, wound healing, the function of steroid hormones (including vitamin D and estrogen), and brain function. Boron is not known to have any clinically relevant interactions with medications. 來源↗

台灣社群（PTT 健身/Health/elderly、Dcard、Mobile01）幾乎無人把「硼」當作骨質疏鬆的獨立保健標的討論。搜尋到的「硼」討論絕大多數是 Dcard 女孩版的「硼酸」治療念珠菌（與骨骼無關）。骨鬆討論被鈣（海藻鈣、檸檬酸鈣）與維他命 D3 完全主導，硼僅在少數綜合配方中作為微量添加成分（如三多 D3、含 250mg 硼之 D 配方）被一筆帶過，無實測心得、無社群推薦品牌、無副作用反饋。屬冷門題材，無可靠在地討論。
