Boron is a trace mineral essential to human health and must be obtained from diet or supplements. This nutrient recently gained popularity after researchers found that it helps the bones use calcium. Increased boron levels in the soil have been associated with a lower risk of osteoarthritis.

Boron as a supplement is used to support building strong bones, treating osteoarthritis, as an aid for building muscles and increasing testosterone levels, and for improving thinking skills and muscle coordination. Women sometimes use capsules containing boric acid, the most common form of boron, inside the vagina to treat yeast infections. Boron is a common mineral found in many of the joint support formulas, due to its elements that support bone health and osteoarthritis prevention.
