Boron

Boron is a trace element that is naturally present in many foods and available as a dietary supplement. 

Boron is not classified as an essential nutrient for humans because research has not yet identified a clear biological function for boron . However, it might have beneficial effects on such functions as reproduction and development, calcium metabolism, bone formation, brain function, insulin and energy substrate metabolism, immunity, and the function of steroid hormones (including vitamin D and estrogen).

The U.S. Department of Agriculture’s (USDA’s) FoodData Central does not list the boron content of foods or provide lists of foods containing boron. Therefore, information on boron levels in foods is limited.
