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.

good calcium formula

Posted by Reviewer2380793 on Apr 19, 2012

I don't take much calcium because it dries me out for some reason. I end up getting a uti and constipation if I take any calcium every day. But when I do take calcium this is the one I take because of the balance of minerals.

I could've gotten a WAY better deal

Posted by Reviewer3198685 on Jan 07, 2012

Since ordering, I've discovered I grossly overpaid for these Boron capsules. I can get nearly triple the amount of tablets for the same price for another online supplier. As far as efficacy, it's too soon to tell. Order turnaround was excellent. It arrived from Cal. to the East Coast in a couple days.
