What Is It?
Boron is a biologically dynamic ultra trace element important in human metabolism. A recommended dietary allowance for boron has not been established, although surveys indicate that average daily intakes of boron range between 0.5 and 3.1 mg. Based on animal studies, humans probably have a daily requirement of 1 mg a day.
Boron was originally used in the 1870s as a food preservative in the form of boric acid for perishables such as fish, meat, and dairy products. In 1904, however, reports surfaced that human volunteers consuming more than 500 mg of boric acid per day for 50 days showed disturbances in appetite, digestion, and general health. By the 1950s boron was outlawed throughout the world as a food preservative. It was not until the 1980s that nutritionists and biochemists realized the importance of boron in human health.
The physiological function of boron remains to be elucidated, but studies demonstrate its involvement in several processes, especially macromineral metabolism. Studies show that it is a metabolic regulator and plays an important role in cell membrane function. Recent studies suggest that boron is important for calcium utilization in the body. In human deficiency studies, supplementation with boron improved several parameters including mental alertness, memory, mineral metabolism, and blood hemoglobin.
