Boron: benefits, side effects, dosage and interactions


Boron is a mineral found in foods such as nuts and in the environment. Boron is also sometimes taken in supplement form to enhance athletic performance and improve thinking or coordination. Some women use boron to treat yeast infections. Not all of these uses are supported by scientific evidence.

What is boron used for?

Research shows that boron is involved in the metabolism of vitamin D and estrogen and can affect cognitive function. Boron supplements are sometimes said in alternative medicine to help with bone mineral density and prevent and / or treat the following health problems:

  • Diabetes
  • High cholesterol
  • Symptoms of menopause
  • Osteoarthritis
  • Osteoporosis
  • Rheumatoid arthritis
  • Psoriasis

Additionally, boric supplements are designed to enhance athletic performance by increasing testosterone levels and reducing inflammation .

According to the National Institutes of Health (NIH), there is still not enough scientific evidence to support most of the health claims for boron supplements.

Boron for yeast infections

One of the most popular uses for boron is to treat vaginal yeast infections. Some women use boric acid capsules in the vagina because they believe that boron can make the vagina more acidic.

Boric acid is a form of boron. It is sometimes said to help with recurring vaginal yeast infections when used as a vaginal suppository. Boric acid should never enter.

For example, in a 2003 review of studies from the Gynecology and Obstetrics Service , researchers analyzed a number of studies on the use of various types of complementary and alternative medicine in the treatment of yeast infections. They found that boric acid appears to be beneficial for women with recurrent yeast infections who are resistant to conventional treatments, but be aware that in some cases, boric acid can lead to vaginal burning and other side effects.

In a more recent review of research published in the Journal of Women's Health in 2011, researchers concluded that "boric acid is a safe, alternative, and cost-effective option" for women with recurrent yeast infections. However, boric acid can be absorbed through the skin and a safe dose has not been established.

So while there has been some research linking the use of boron supplements to treat yeast infections (yeast infections), most of the research is outdated and the quality of the research has been questioned, so this benefit cannot be confirmed. .

Possible side effects.

Consuming too much boron can lead to nausea, vomiting, indigestion, headache, and diarrhea. At higher doses, skin flushing, seizures, tremors, vascular collapse, and even fatal poisoning have been reported at a dose of 5-6 grams in infants and 15-20 grams in adults.

The NIH warns that boron supplementation (or high boron intake in the diet) can be harmful for people with hormone-sensitive conditions, such as breast cancer, endometriosis , and uterine fibroids . The concern is that boron can increase the levels of hormones such as estrogen and testosterone in some people .

Also, boron is primarily eliminated through the kidneys, so people with kidney disease or problems with kidney function should avoid it.

Pregnant women, nursing mothers, and children cannot take boron or use boric acid in any form, including suppositories, topical boric acid powder, or borax solution to clean baby pacifiers.

If you are considering using a strawberry, consult your doctor first. It is important to note that self-medication for a disease and avoiding or delaying standard treatment can have serious consequences.

Dosage and preparation

Boron is found in many foods, including avocados, red apples, peanuts, raisins, prunes, walnuts, potatoes, and peaches. Although small amounts of boron are believed to be important for various metabolic functions, the recommended daily intake (RDA) has not been established. The tolerable upper intake level (UL) for boron (defined as the maximum dose at which no harmful effects are expected) is 20 mg per day for adults and pregnant or lactating women over 19 years of age .

While there is some evidence that vaginal use of boric acid suppositories has the potential to treat vaginal yeast infections, given the lack of scientific support, the ubiquity of boron in food and water, and safety concerns with excessive consumption, oral boron supplementation is probably one of them. disregarded. If you plan to use boron in any form, be sure to speak with your doctor first to weigh the pros and cons.

What to look for

Boric supplements, available for purchase online, are sold in many health food stores and supplement stores.

Note that if you decide to purchase a supplement such as boron, the NIH recommends that you look at the supplement label on the product you are purchasing. This label will contain important information, including the amount of active ingredients per serving and other added ingredients (such as fillers, binders, and flavors).

Additionally, the organization invites you to search for a product that is approved by a third-party quality testing organization. These organizations include the United States Pharmacopeia,, and NSF International. A seal of approval from one of these organizations does not guarantee the safety or effectiveness of a product, but does provide assurance that the product has been manufactured correctly, contains the ingredients listed on the label, and does not contain harmful levels of contaminants.
