About Boron
Boron is a trace mineral involved in bone metabolism, steroid hormone regulation, and inflammatory response. A seminal study by Nielsen (1987) showed 3 mg/day boron reduced urinary calcium and magnesium excretion and increased serum estradiol and testosterone in postmenopausal women on a low-boron diet. May also support cognitive function — boron deprivation impaired EEG measures of alertness in controlled trials. Not classified as essential but increasingly recognized as conditionally beneficial for bone and joint health.
