Product Overview


  • Plus Magnesium, Vitamin D3 and Co-Factors
  • Dietary Supplement
  • Chelated Boron with Calcium

Tri-Boron Plus capsules are easier to swallow and assimilate. A University of Maryland study published in "American Pharmacy" has concluded that many brands of calcium tablets dissolve so slowly that they pass from the stomach before they can take effect.

Tri-Boron Plus capsules disintegrate and break down quickly in the stomach.

Tri-Boron Plus contains no added salt (sodium), artificial colors or preservatives.

Tri-Boron Plus is a combination of three natural, highly utilizable, chelated sources of the trace mineral boron. Studies indicate that boron improves calcium metabolism and utilization.

Tri-Boron Plus capsules synergistically combine the trace mineral boron with calcium, magnesium and vitamin D3 plus trace minerals zinc, manganese and copper which are integral co-factors for several enzymes involved in bone metabolism.

Suggested Use

Take 2 capsules twice daily, preferably two capsules with breakfast and two capsules with an evening meal. Studies indicate that calcium is best utilized when taken in multiple dosages.

Other Ingredients

Potato starch, gelatin, starch, croscarmellose sodium, purified water, soy lecithin, magnesium stearate, medium chain triglycerides.
