when you have boron deficiency, it causes your kidneys and liver to eliminate calcium, magnesium and vitamin D

this makes cramping worse, amongst other things

boron is the 5th element, and vegetables are the best source, and it is also oestrogenic, which means if you consume a lot of it you get a bit girly

but if you don't have enough it makes you weak and softens your bones and makes you dull and low alertness, gives you cramps, makes you nervous, so many nasty nasty things but good luck learning about boron deficiency

barely gets a mention on NIH websites https://ods.od.nih.gov/factsheets/Boron-HealthProfessional/
