The role of boron is still being discovered and knowledge about this trace element is still quite limited. The primary roles include muscle building, contributing to the health of cell membranes, aiding in various enzyme reactions, preventing calcium loss in menopausal women, and helping to maintain normal levels of minerals and hormones required for healthy bones.
For those who like drinking, you'll be glad to know Boron is found in beer and cider. Mostly, Boron is found in plant sources such as apples, raisins, tomatoes, carrots, grapes, nuts, leafy vegetables, pears, legumes, and nuts.
A deficiency in boron can lead to bone conditions such as osteomalacia, osteoarthritis, and poor bone development in general.
