Not that I recommend waiting for the symptoms to arrive, medication et al; more going for the supplementing of it, so one hopefully can prevent some conditions.
"Boron is far from being a boring trace element known only to specialists. The similarities it shares with carbon—the most important structural element in organic chemistry—and the important chemical and electronic differences between the two make boron an exciting candidate for a wide range of applications. For the time being, only some pharmaceutical and biotechnology companies, as well as a handful of biomedical scientists, are exploring the diversity and utility of boron-based compounds. Yet, once their research shows the true potential of carbon's over-looked neighbour, boron might well find its way into the catalogue of useful elements for standard research." http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2637326/
