Boron

How does Boron work?

Boron seems to affect the way the body handles other minerals such as magnesium and phosphorus. It also seems to increase estrogen levels in older (post-menopausal) women and healthy men. Estrogen is thought to be helpful in maintaining healthy bones and mental function. Boric acid, a common form of boron, can kill yeast that cause vaginal infections.

Are there safety concerns?

Boron is LIKELY SAFE for adults and children when used in doses less than the Upper Tolerable Limit (UL) (see dosage section below). There is some concern that doses over 20 mg per day, the UL for adults, might harm a man's ability to father a child.

Boric acid, a common form of boron, is LIKELY SAFE when used vaginally for up to six months. It can cause a sensation of vaginal burning.

Boron is POSSIBLY UNSAFE for adults and children when taken by mouth in high doses. Large quantities of boron can cause poisoning. Signs of poisoning include skin inflammation and peeling, irritability, tremors, convulsions, weakness, headaches, depression, diarrhea, vomiting, and other symptoms.

Also, boric acid powder, a common form of boron, is POSSIBLY UNSAFE when applied in large amounts to prevent diaper rash.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Boron is LIKELY SAFE for pregnant and breast-feeding women age 19-50 when used in doses less that 20 mg per day. Pregnant and breast-feeding women age 14 to 18 should not take more than 17 mg per day. Taking boron by mouth in high doses is POSSIBLY UNSAFE while pregnant and breast feeding. Higher amounts may be harmful and should not be used by pregnant women because it has been linked to birth defects. Intravaginal boric acid has been associated with a 2.7- to 2.8-fold increased risk of birth defects when used during the first 4 months of pregnancy.

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 exposure to estrogen, avoid supplemental boron or high amounts of boron from foods.

Kidney disease or problems with kidney function: Do not take boron supplements if you have kidney problems. The kidneys have to work hard to flush out boron.
