Boron strengthens bones and improves uptake of calciummagnesium and vitamin D.

What are its health benefits?

Boron is a trace mineral, which means you need only the tiniest amounts for good health. It acts as a trigger for some very important physiological processes. For example, its uses include helping to regulate levels of other essential minerals, including calcium, magnesium and phosphorus, which suggests it may help to prevent osteoporosis.

Benefits also include the metabolism of hormones. For example, it raises testosterone levels in men and helps to build muscle. Boron affects memory and brain function, and it keeps cell walls strong so that proper transfer of nutrients can occur throughout the body.

There is also a link between boron and arthritis. Increased levels in the soil have been associated with a lower risk of osteoarthritis.

Do you have a deficiency?

Excessive sweating and diuretics (so-called “water pills” that help your body get rid of unneeded water and salt through the urine) can cause the loss of trace minerals such as boron.

Warning signs of a boron deficiency can include:

Boron deficiency may also contribute to the formation of kidney stones and may decrease mental alertness.
