Boron

Evidence: moderate_human

Mechanism of Action

Boron influences calcium, magnesium, and phosphorus metabolism, likely through effects on cell membrane function and transmembrane signaling. It reduces urinary calcium and magnesium excretion, increases serum 25(OH)D and estradiol levels, reduces SHBG (sex hormone-binding globulin) thereby increasing free testosterone, and inhibits inflammatory markers (CRP, TNF-alpha) via NF-kB modulation. Boron also inhibits serine proteases and may modulate the activity of steroid hormone hydroxylases. It plays a role in bone formation by influencing osteoblast and osteoclast activity.

Dosing Protocol

Standard: 3-6mg daily

Loading: 9-12mg/day for testosterone optimization (short-term, 1-2 weeks)

Maintenance: 3-6mg/day

Administration: oral

Timing: With meals. Often taken with Vitamin D/K stack.

Duration: ongoing

Notes

Significantly underutilized mineral in clinical practice. The testosterone/estradiol modulation makes it valuable in male hormone optimization — typically a rapid SHBG reduction within 1 week. The bone health synergy with calcium, magnesium, vitamin D, and K2 is well-established. One of the cheapest supplements available. The 3mg dose is sufficient for bone health; 6-9mg for hormone optimization. Estrogen-sensitive populations need monitoring.

Stacking

  • Vitamin D3
  • Magnesium
  • Calcium
  • Zinc
  • Tongkat Ali

Interactions

  • Estrogen therapy (HRT) [LOW] — Boron increases estradiol levels — may potentiate estrogen therapy

Contraindications

  • Estrogen-sensitive cancers (boron increases estradiol)
  • Renal impairment (boron is renally excreted)

Side Effects

  • Nausea at high doses
  • Diarrhea
  • Skin rash (rare)
  • Generally very well tolerated at standard doses
