There was a comment stuck in “spam” for no reason I could see, so I clicked the link in it to a video, and while watching, moved the comment back to the regular queue and approved it. Well, it had been ‘stuck’ long enough it is several days back in the comment queue and I can’t find it again (well, could find it given enough hours). So if you are the poster, please take a bow for your h/t!
This is a rather dramatic video about the use of Boron in arthritis and other metabolic issues. Among the interesting bits, are the specific identification of the Boron transporter (and it is dedicated to boron, so pretty much proves it is essential).
The major thrust is that it strongly improves bone health, reduces arthritis, and has many other benefits including on teeth. Lack of boron leads to lack of bone growth and tooth loss. Calcium loss in urine is reduced with boron+magnesium. Reduced calcium means less tendency to form kidney stones. There is also an inverse relationship between Boron and prostate cancer, per the presenter. Boron is also important to the hydroxylation of steroids, including making Vitamin D and Testosterone more active, and also transforms Estrogen into a form that is more helpful and less prone to breast cancer promotion.

Also note that there are links in tips here: h/t Sabertoothed to more Boron information.
It is sure looking like Boron deficiency is a big deal, especially in those places with poor soil and dietary boron content.
