The Role of Boron in the Diet and as a Dietary Supplement.

Our assessment

This 2026 review paper examined the role of boron as a trace element in human nutrition. Because this is a review article, it does not involve a specific study design, sample size, or participant duration. The authors analyzed existing evidence on boron from food and drinking water, focusing on its potential health benefits. What this means for you: This is a summary of current science, not a new clinical trial, so its conclusions are based on the quality of the studies it reviewed.

How it works

The review suggests that boron supplementation may support several areas of health, including bone health, cognitive function, mineral and hormonal metabolism, the body's antioxidant defense system, body weight regulation, and inflammation. What this means for you: Boron is a trace element found naturally in many foods. The data suggests it might play a role in keeping your bones strong, your thinking sharp, and your body's systems balanced, but these findings are from a review of emerging evidence, not a single large study NIH DSLD ↗.

Safety profile

Data not available. The provided data does not include specific side effects or adverse event reports from the FDA for boron supplements. No report counts are available FDA FAERS ↗.

Our recommendation

Because this is a review of emerging evidence, not a large-scale clinical trial, we recommend a cautious approach. Boron is naturally present in a balanced diet through foods like fruits, vegetables, and nuts. If you are considering a supplement, it is best to consult with a healthcare provider first, as the long-term effects and optimal dosage are not fully established by the data provided NIH DSLD ↗.
