Boron: 4. What are the effects of boron on humans …

1 · Boron acts in the same way in humans as in other mammals. These similarities help to make it possible to make reliable predictions of effects on humans from effects observed on laboratory animals such as rats. When swallowed and inhaled, boron is widely distributed throughout the body, and some is taken up by the bones. It is then rapidly excreted, with boron incorporated in bone taking a ...Borates also have a variety of industrial uses. For example, boron is a micronutrient essential to plant growth. Our boron contains calcium-free sodium borates, which are optimal for agricultural use. We refine our borate minerals into boron-rich micronutrient products that help farmers, around the world, grow better crops in greater quantities.
