Jump Ahead to the Top 10 Boron Products

What is Boron?

Boron is a vital trace mineral found naturally in some foods, including certain fruits and nuts. Some boron foods include walnuts, avocados, almonds, broccoli, pears, red grapes, prunes, potatoes, honey, oranges, red apples, and raisins. A typical diet could provide anywhere from 0.25mg to 3.25mg of boron per day.

Because no essential biological role has been identified for boron, no Recommended Daily Allowance has been established. It’s not considered an essential nutrient for human life, but it does have some interesting effects on the body’s processing of other nutrients. When taking in supplement form, boron can be used for a variety of purposes.

Uses of Boron

Boron has some effects on its own, but many of its purported benefits have to do with its effect on other minerals. Boron changes the way the body processes key nutrients including magnesium and calcium. Boron has been studied in clinical trials for the following applications:

  • Boron Deficiency – although rare, boron deficiency can contribute to osteoarthritis-like symptoms in joints and bones, along with other symptoms. Boron deficiency is not a clearly defined medical condition, making it difficult to diagnose, but experts have advised that taking boron in supplement form may help you avoid a deficiency.
  • Joint Health – a clinical review found that boron is an essential nutrient for healthy bones and joints – although the authors warned that further research was required. It is thought that boron affects the body’s processing of other key nutrients, including calcium and magnesium, which is one reason the mineral is said to have joint health boosting properties. It’s unclear whether supplemental boron has a positive effect on otherwise healthy individuals, but initial research shows promise in its ability to support joint health.
  • Period Pain – some research has suggested that large doses of boron (10mg/day) taken around the time of menstrual bleeding may help to reduce painful period symptoms in young women. Note that higher doses are required for these effects (the standard boron dosage is about 3mg). Further research is required.
  • Testosterone – preliminary evidence suggests that boron may reduce estrogen levels in healthy males, leading to a potential increase in free testosterone levels. Although promising, this was a small-scale study, so more research is needed.
  • Vaginal Infection – boric acid, a form of boron, can be used to lessen symptoms of yeast infections and other vaginal infections. A review of clinical evidence concluded that “boric acid is a safe, alternative, economic option for women with recurrent and chronic symptoms of vaginitis…” However, boric acid must be applied topically in order to fight infection – it’s unclear if consuming boron supplements will have any effect on vaginal infections.
  • Other Uses – there are several other purported uses of boron that have not been thoroughly studied enough to reach a conclusion. These uses include countering vaginal infections (when applied topically), supporting mental function in older adults, and improving osteoarthritis and osteoporosis symptoms. Again, all these uses have been studied, but there is insufficient evidence to reach a conclusion one way or the other.

How to Take Boron

Boron should be taken once daily, with or without a meal. The standard recommended dose is 3mg per day. This amount has been widely studied and ruled as a safe dosage level.

For some applications, higher doses of 6mg to 10mg are recommended. notes that the ideal dosage is simply not known at this time, because no RDA has been established by the federal government, and more clinical research is required. The Tolerable Upper Intake Level (which refers to the maximum amount before any negative effects would be expected), is listed at 20mg per day. Most people will not experience adverse effects if they stay under this amount.

Boron Side Effects and Precautions

When taken in doses less than the UL level of 20mg per day, boron does not typically cause side effects. In large doses, boron can cause poisoning and symptoms including skin peeling and inflammation, weakness, irritability, headaches, nausea, and more.

Certain groups of people should exercise caution when considering taking boron. If you fall into any of these categories, you should speak with your doctor before beginning supplementation:

  • Pregnant women
  • Breastfeeding women
  • Those with hormone-sensitive medical conditions
  • Those with breast, uterine, or ovarian cancer
  • Those with kidney disease or compromised kidney function

What to Look for in a Good Boron Supplement

A good boron product should contain an adequate quantity of the active ingredient (usually 3mg). Additionally, it should contain few to no fillers, additives and unnecessary ingredients. It should be made by a reputable company that follows good manufacturing processes, and sources ingredients with care. Lastly, it should be offered at a reasonable price.
