Chemical Symbol



Boron is a mineral that is found primarily in plants and is essential for the growth of plants. Boron is essential for the health of bones and joint function. It is often given to those suffering from arthritis and can be taken to help bone density. Some studies show that it may have a minor effect on mental health, but the research has been minimal.


Boron seems to be essential for healthy bone and joint functioning particularly in women; based on previous research it seems to affect cell membranes and the way signals are transmitted across them. Boron also affects the way steroid hormones are metabolized and may play a role in converting vitamin D to it active form and metabolizing the male sex hormone.

Forms Available

Recommended Intake

There are no established recommended Daily Allowance (RDA) values due to the need for further research, but the Tolerable Upper Intake Level (UL) values are as follows:

Children and Adolescents

  • 1 to 3 years old: 3 milligrams per day (mg/day)
  • 4 to 8 years old: 6 mg/day
  • 9 to 13 years old: 11 mg/day

  • Pregnant and lactating older than 19 years old: 20 mg/day
  • Pregnant and lactating 14 to 18 years old: 17 mg/day


Boron deficiencies have been shown to affect calcium and magnesium metabolism and affect the makeup of bones. The effect boron has on bone makeup and structure is similar to that of osteoporosis, this is more than likely due to the increased absorption and excretion of calcium and magnesium. Some epidemiological studies have indicated a linked between boron deficiencies and osteoarthritis as well.

Sources in the Diet

Plant foods like fruits, vegetables, and nuts are rich in boron, however the amount of boron in each food depends on the soil in which it was grown. Some examples of boron rich foods are avocados, red kidney beans, prunes, chickpeas, dried peaches, raisins, pears and almonds.
