Benefits of Boron

Evidence-Based Benefits

• Bone health — Naghii and Samman (1993) showed boron supplementation reduced urinary calcium excretion by 44% and increased serum 17-beta estradiol and testosterone in postmenopausal women, supporting bone preservation
• Testosterone support — a 2011 Naghii et al. study found 10mg boron daily for 7 days increased free testosterone by 28% and decreased estradiol by 39% in healthy men
• Anti-inflammatory — calcium fructoborate (CFB) reduced CRP levels by 31% in a 2014 RCT by Pietrzkowski et al. in subjects with elevated inflammatory markers
• Vitamin D metabolism — boron supplementation increases serum 25-hydroxyvitamin D levels, particularly in vitamin D-deficient individuals
• Joint comfort — a 2004 Newnham study found boron supplementation improved joint comfort in areas with low-boron soil and water

What the Research Says

Boron is an essential nutrient with diverse applications in health and agriculture. Early research by Nielsen et al. (1987) demonstrated that boron deprivation in postmenopausal women increased urinary calcium loss, highlighting its role in mineral metabolism. Subsequent studies have explored its effects on hormone levels and inflammation. Naghii et al. (2011) found that 10mg daily boron supplementation elevated testosterone levels in a small but well-designed study. Pietrzkowski et al. (2014) showed significant reductions in C-reactive protein (CRP) in a double-blind RCT, suggesting anti-inflammatory properties.

Recent advancements include the use of boron neutron capture therapy (BNCT) for cancer treatment. Sun et al. (2026) conducted a meta-analysis of 7 studies (n=361), finding BNCT effective for locally recurrent head and neck cancer with an overall response rate (ORR) of 70% and a 2-year survival rate of 45%. Mao et al. (2025) highlighted BNCT's stronger immunogenicity compared to traditional radiation, supporting its potential combined use with immunotherapy. Younous et al. (2024) reviewed 40 studies, concluding that BNCT shows promising efficacy across various cancers with manageable safety but noted variability in outcomes and adverse effects.

In agriculture, Zinzala et al. (2026) found that applying 3 kg ha⁻¹ boron and 10 kg ha⁻¹ zinc significantly increased sugarcane yield, quality, and nutrient uptake without interaction effects on ratoon crops. These findings underscore boron's importance in both health and agriculture, though larger confirmatory trials are needed to validate its benefits across different applications.
