Plants need boron for proper health, but it's not known whether humans do. However, boron does seem to assist in the proper absorption of calcium, magnesium, and phosphorus from foods, and slows the loss of these minerals through urination. Very preliminary evidence suggests that boron supplements may be helpful for osteoarthritis and osteoporosis .
No dietary or nutritional requirement for boron has been established, and boron deficiency is not known to cause any disease. Good sources include leafy vegetables, raisins, prunes, nuts, non-citrus fruits, and grains. A typical American daily diet provides 1.5 to 3 mg of boron.
Finally, boron is sometimes recommended as a treatment for rheumatoid arthritis , but there is no evidence to support this use.
Since the therapeutic dosage of boron is about the same as the amount you can get from food, it is probably fairly safe. Unpleasant side effects, including nausea and vomiting, are only reported at about 50 times the highest recommended dose.
