Boron (B)
B
Overview
Boron is an ultratrace mineral found in plant foods such as dried fruit, nuts, legumes, avocados, and some vegetables. It is not classically listed among the major essential minerals, but human research suggests biological roles in bone metabolism, vitamin D and sex-hormone handling, and inflammatory signalling. Within the BRAIN Framework, boron is treated as a secondary supportive micronutrient — relevant to hormonal and metabolic context rather than as a direct neurotransmitter cofactor. Typical dietary intakes are low (often 1–3 mg/day in mixed diets) and come primarily from fruits, vegetables, nuts, and legumes.
Dietary absorption and meal context
- Main sources: Raisins, prunes, almonds, hazelnuts, legumes, avocados, and some leafy vegetables are relatively boron-dense.
- Matrix effects: Boron intake usually tracks plant-food diversity; highly refined diets may provide little boron.
- Safety note: Chronic very high supplemental boron intake can be harmful; food-first patterns are preferred unless clinically directed.

Biological Mechanisms and Implications
| Biological Target | Therapeutic Areas | Mechanism of Action |
|---|---|---|
| BRS6 - Metabolic & Neuroendocrine Stress | — | Ultratrace boron status has been associated in human studies with markers of inflammation and metabolic handling; interpreted as a supportive dietary factor within whole-food patterns rather than a primary glucose-control lever |
