Synergy
What is happening. Boron reduces urinary calcium excretion and supports calcium utilization for bone health.
Mechanism. Boron reduces urinary excretion of calcium and magnesium, likely by influencing renal tubular reabsorption and steroid hormone metabolism.
Recommendation. 3mg boron daily may help retain calcium and support bone mineral density.
