Boron is a trace element
Boron appears in foods and supplements and is studied in relation to bone and mineral metabolism, among other areas. Men’s-supplement marketing sometimes extends that research into strong hormone claims that exceed what a small or indirect study can establish.
HorseWood label context
A published HorseWood formula page listed 20 mg of Boron Amino Acid Chelate per two-capsule serving. A label may state the mass of the chelate ingredient rather than elemental boron, so the exact elemental contribution should be confirmed from the current Supplement Facts panel/manufacturer if it is not explicit.
Total exposure matters
When minerals are present in several supplements, total intake can matter more than one product in isolation. Bring the full list of supplements to a clinician or pharmacist if you have questions about dose or interactions.
