Boron (symbol B, atomic number 5) is a naturally occurring trace mineral that plays an important role in human health, although it is not officially classified as an essential nutrient. Found in fruits, vegetables, nuts, legumes, and drinking water, boron has gained attention for its potential benefits in supporting bone health, hormone balance, brain function, and inflammation control.
Research suggests that boron may influence the metabolism of minerals such as calcium, magnesium, and phosphorus while helping the body utilize vitamin D more effectively. Due to these properties, boron supplements have become increasingly popular among athletes, older adults, and individuals seeking better joint and bone health.
This guide explores everything you need to know about boron, including its benefits, side effects, recommendations, medicinal uses, and safety precautions.
What is Boron?
Boron is a trace mineral naturally present in soil, water, plants, and certain foods. Plants absorb boron from the soil, making fruits, vegetables, nuts, and legumes the primary dietary sources.
Although the human body requires only small amounts of boron, it appears to support various biological processes, including:
- Bone metabolism
- Hormone regulation
- Cognitive function
- Wound healing
- Mineral absorption
- Inflammatory response
Boron is available as a dietary supplement in forms such as boron citrate, boron glycinate, boron aspartate, and borax-derived compounds.
