Boron glycinate bonds the trace mineral boron to the amino acid glycine. This chelated form supports absorption and tends to be easier on the stomach than boric acid or sodium borate. People use it to help maintain bone density, joint flexibility, and healthy hormone levels, including testosterone and estrogen balance.
Many adults take boron glycinate daily for joint comfort as they get older, or for general hormonal support. Others combine it with vitamin D and magnesium. Taking it with a meal often improves tolerance and absorption.
Watch your intake carefully. Doses above 20 mg per day can trigger nausea, headache, or diarrhea. Skip it or talk to a doctor first if you have kidney problems, take hormone-sensitive medications, or live with a hormone-sensitive condition, since boron can shift estrogen and testosterone levels.
