Boron is not classified as an essential human nutrient because research has not yet identified a clear biological function for Boron. However, it might benefit functions such as calcium metabolism, brain function, reproduction and development, bone formation, insulin metabolism, immunity, and the roles of steroid hormones (including vitamin D and estrogen). Boron does not accumulate in most body tissues, but bone, nails, and hair have higher boron levels than other body tissues.

• Fruits and fruit juices, such as peaches and grape juices
