Boric acid is a form of boron.

It is sometimes said to help with recurrent vaginal yeast infections when used as a vaginal suppository.

(Keep in mind that you should never ingest boric acid by mouth).

However, this association has not been evaluated in clinical trials.

More research is needed to determine if boron indeed has any effect on cancer.

However, no human studies have proven that boron can impact bone density.

More research is necessary to confirm that boron has a direct positive impact on bone health.

Boron Deficiency

A deficiency in boron is rare.

Most Americans get enough boron from dietary sources.

Boron status (measured in urine or blood) is not routinely checked.

What Are the Side Effects of Too Much Boron?

The concern is that boron may increase production of hormones such as estrogen and testosterone in certain individuals.

There are also reports that boron supplementation can reduce phosphorus levels in the blood.

If you’re considering taking boron, consult your healthcare provider first.

It’s important to note that self-treating a condition and avoiding or delaying standard care may have serious consequences.

These organizations include U.S. Pharmacopeia, ConsumerLab.com, and NSF International.

A seal of approval from one of these organizations does not guarantee the product’s safety or effectiveness.

Summary

Boron is a natural mineral that we can get from plant-based foods.

There is little research to support further supplementation with boron.

However, some research suggests that it may benefit osteoarthritis and yeast infections.

Additionally, there is no RDA set for boron.

Most healthy people are likely getting adequate boron through their diet alone, so supplementation may not be necessary.

It is essential to consult with a healthcare provider before starting any supplements.
