Boron for Better Bone Health
Although not often spotlighted in public health recommendations, boron is a mineral that is critical to our health, and has been of special interest in women in relationship to bone health and osteoporosis (bone softening). Boron is a trace mineral required to convert estrogen and vitamin D to their most active forms (17-beta-estradiol and 1,25-(OH)2D3 respectively). Estrogen levels drop after menopause causing osteoclasts to become more sensitive to parathyroid hormone, which signals them to break down bone. Studies have shown that boron provides protection against osteoporosis and reproduces many of the positive effects of estrogen therapy in postmenopausal women. Raisins are among the top 50 contributors to total dietary boron in the U.S. diet.
