yeah, if you are deficient in boron, your kidneys eliminate calcium and magnesium and this leads to bone and nerve problems
it definitely also affected my mother too, she almost had a hip fracture from a fall down stairs about 15 years ago, and was diagnosed with osteoporosis, which is a calcium deficiency based problem but magnesium is also critical to absorbing calcium so boron is a limiter there, and she also has celiac like me, but not quite as severe
anyhow, yeah, boron is a thing, and i like to joke about how it's the "fifth element" yes, it's element 5.
