Boron Safety & Side Effects

Our assessment

Based on FDA data, the overall safety profile for boron is limited. FDA received 4 adverse event reports for boron-containing products. The data suggests that side effects are rarely reported, but the small number of reports means that a comprehensive safety profile cannot be fully established from this data alone FDA FAERS ↗.

How it works

Boron is a trace element found in a healthful diet. It may play a role in how the body handles other nutrients, but its exact mechanisms are still being studied NIH ODS ↗ NIH DSLD ↗.

Safety profile

Based on FDA data, 4 adverse event reports were received for boron. Data on specific side effects with report counts is not available from the provided FDA data. Excessive boron intake can be toxic, and the difference between a safe and harmful dose is narrow NIH ODS ↗.

Our recommendation

Data on drug interactions for boron is not available from the provided data. Because excessive boron intake is toxic, do not exceed the tolerable upper intake level of 20 mg per day for adults NIH ODS ↗. Obtain boron from a healthful diet rather than supplements unless directed by a healthcare provider NIH DSLD ↗.
