Boron is a non-metallic element and is present in some foods we eat. Boron helps the body absorb calcium, magnesium, phosphorus, copper and vitamin D. It is important for strengthening and preserving bone mass in the human body.
It is contained in egg yolk and milk.
In addition, boron is an important trace element that contributes to the normal functioning of many biochemical processes in plants and animals.
It has been proven that if Boron is missing in the soil, many plants ( peas, beets, flax, alfalfa, tobacco, …) die.
