Boron helps prevent loss of calcium, magnesium and phosphorus through the urine. It also supports proper blood levels of estradiol—a precursor to estrogen. An advanced amino acid chelate form is used for superior absorption. Bluebonnet’s Triple Boron 3 mg Capsules provide the trace mineral boron, which is multicomplexed with citrate, aspartate and glycinate. Available in easy-to-swallow vegetable capsules for maximum assimilation and absorption.
