Bone Builder® MBD

MCHC with Magnesium, Boron & Vitamin D

Bone Builder MBD is an excellent, comprehensive bone support formula that features the same calcium-rich MCHC found in original Bone Builder®, but with other bone-nourishing nutrients.


  • Features a 2:1 ratio of calcium to magnesium.
  • With more than one-half of the total body stores found in bone tissue, magnesium has been shown to play an important role in bone metabolism.*
  • Boron is a trace mineral that may support bone health through its involvement in vitamin D and estrogen metabolism.*
  • Vitamin D is an essential nutrient that helps stimulate calcium absorption and regulate calcium and phosphorus levels in the body.*


Take two tablets twice daily or as directed by your healthcare practitioner.
