mineral · for back pain
Boron
Thought to calm inflammation around the spine and support bone density there.
Say that in clinical terms
Anti-inflammatory effects reduce vertebral inflammation. Supports bone mineral density in lumbar spine.

Who was studied: Studied in postmenopausal women with osteoporosis. Most back pain is mechanical and in working-age adults.
Boron clinical trial evidence concentrates on three areas: osteoarthritis joint pain (a 1994 double-blind pilot study of 6 mg/day for 8 weeks in 20 OA patients by Rex Newnham; not a numbered DOI); rheumatoid arthritis inflammatory markers (calcium fructoborate and sodium tetraborate studies); and primary dysmenorrhea pain (PMID 25906949, a triple-blind RCT of 10 mg/day boron). None of these target back pain or lumbar pain. The PubMed search for 'boron supplementation back pain humans' returned zero results. The NIH ODS Boron health professional fact sheet does not list back pain as a studied outcome. Web searches across general medical literature and Cochrane did not surface any trial — rand
How much to take
daily
3–6 mg
Particularly beneficial for spinal osteoarthritis. Combine with vitamin D and magnesium.
Before you take it
- NIH ODS Tolerable Upper Intake Level (UL) for adults age 19+ is 20 mg/day; the FNB set this threshold based on reproductive and developmental toxicity observed in animal studies.
- The UL applies to pregnant and lactating women: 17 mg/day for ages 14-18, 20 mg/day for ages 19+, using the same animal reproductive-toxicity basis.
- Breast milk, formula, and food are the only recommended boron sources for infants under 6-12 months; no supplemental boron is advised for that age group.
- NIH ODS explicitly states boron has no known clinically relevant interactions with any medication.
- Excessive acute intake can cause nausea, gastrointestinal discomfort, vomiting, diarrhea, and skin flushing; historical case reports of extremely high cumulative ingestion (on the order of 15,000-20,000 mg total) have been fatal.
What we make of it
No trial has tested boron for back pain. The evidence is about bone density in postmenopausal women.
The detail
There is no direct evidence here. The study measures bone density in the spine, which is several steps removed from back pain — the reasoning runs boron, then denser bone, then fewer fractures, then less pain. Most back pain is muscular or disc-related rather than fracture-related, so that chain does not hold for most people. The paper we cite also returns a dead link.
