Boron is a trace mineral naturally occurring in many foods, but it is particularly abundant in peanut butter, wine, raisins and nuts. The U.S. FDA has not established a DV for boron, but growing evidence suggests it is essential to human beings. In the U.S., adult men consume a mean of 1.17 mg/day and women consume 0.96 mg/day. Vegetarian adults consume slightly more 1.
Up to 18 mg/day of boron appears to be safe for adults even if taken for long periods of time. There is no evidence that it is either carcinogenic or mutagenic. No adverse effects have been observed in women taking boron supplements 2.
Mustard sprout The greens and seeds of the Indian, or brown mustard plant, Brassica juncea, have been cultivated in Asia and Europe for thousands of years 3. Growing Indian mustard sprouts in mineral-enriched soil can increase the amount of minerals concentrated in the plant’s tissue. The sprouts can then be used in dietary supplements as sources of essential and trace minerals such as chromium, iron, manganese, selenium and zinc 4.
Boron amino acid chelate A chelate is a chemical compound in the form of a heterocyclic ring, containing a metal ion (in this case boron) attached by coordinate bonds to at least two nonmetal ions. Organic compounds, such as amino acids, are typical chelators.
