Boron seems to affect the way the body handles other minerals such as calcium, magnesium, and phosphorus. It also seems to increase estrogen levels post-menopause. Boric acid, a common form of boron, can kill yeast that cause vaginal infections. Boron may have antioxidant effects.
People commonly use boron for boron deficiency and vaginal yeast infections. It is also used for athletic performance, menstrual cramps, osteoarthritis, osteoporosis, and many other conditions, but there is no good scientific evidence to support many of these uses.
Uses & Effectiveness ?
Likely Effective for
- Boron deficiency. Taking boron by mouth treats and prevents boron deficiency.
Possibly Effective for
Possibly Ineffective for
- Athletic performance. Taking boron by mouth doesn't seem to improve body mass, muscle mass, or testosterone levels in male bodybuilders.
When applied into the vagina: Boric acid, a common form of boron, is likely safe when used for up to six months. It can cause vaginal burning.
Special Precautions and Warnings
When applied into the vagina: Boric acid, a common form of boron, is likely safe when used for up to six months. It can cause vaginal burning. Pregnancy and breast-feeding: Boron is likely safe when taken by mouth during pregnancy or breast-feeding. For those 19-50 years old, do not take more than 20 mg daily; for those 14-18 years old, do not take more than 17 mg daily. Taking boron by mouth in higher doses is possibly unsafe and has been linked to lower birth weights and birth defects. Applying boric acid into the vagina during the first 4 months of pregnancy has also been linked to birth defects.
Children: Boron is likely safe when used appropriately. The amount that is safe depends on the child's age. Boron is possibly unsafe when taken by mouth in higher doses. Large quantities of boron can cause poisoning. Boric acid powder, a common form of boron, is possibly unsafe when applied in large amounts to prevent diaper rash.
Hormone-sensitive condition such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids: Boron might act like estrogen. If you have any condition that might be made worse by estrogen, avoid supplemental boron or high amounts of boron from foods.
Kidney disease: Do not take boron supplements if you have kidney problems. The kidneys have to work hard to flush out boron.
We currently have no information for BORON overview.
In supplements, adults shouldn't consume more than 20 mg daily. For children, the amount that is safe depends on age. Speak with a healthcare provider to find out what dose might be best for a specific condition.
