Tri-Boron Plus Magnesium‚ Vitamin D and Co-Factors from Twinlab® may provide the benefits of boron in a combination with calcium‚ magnesium‚ vitamin D‚ zinc‚ manganese‚ and copper.

Our body requires proper nourishment in order to function efficiently and this potent formula from Twinlab® might provide optimum amounts of some essential nutrients. This powerful formula contains natural‚ highly utilizable sources of boron‚ which could improve the synthesis and utilization of calcium.

Boron is known to help build strong bones and could be useful for osteoarthritis muscle building. Magnesium‚ as present here‚ may work to improve digestion and bone health. Vitamin D is also known to support bone health and could help maintain bone density.

The body obtains vitamin D from the sun‚ but these days most people spend long hours indoor and hardly get exposed to the sun. In case of exposure‚ they are always under the protection of strong sunscreen lotions. Hence‚ a supplement like this one may be essential for replenishing the body’s store of vitamin D.

Calcium is involved in the health of bones‚ teeth‚ and nails. It is one of the most essential nutrients required by the body. The remaining components are co-factors for enzymes involved in bone metabolism.

Tri-Boron Plus Magnesium‚ Vitamin D and Co-Factors from Twinlab® is designed to disintegrate slowly so that the body can obtain all the nutritional benefits.

    • great calcium supplement

      from Kapowsin, WA on 11/08/2021
      I recommended this to a friend many years ago and as she approaches her 90th birthday, she says she does not have any signs of osteoporosis. I also have been using it for a long time and it does not disappoint me. I was a little disappointed with it being in a plastic bottle rather than the glass bottle my last one was in. It arrived in good shape when the company said it would be here. This is a blip from Twin Labs: 'Studies indicate that Boron improves Calcium Metabolism and utilization. Tri-Boron Plus capsules synergistically combine the trace mineral Boron with Calcium, Magnesium and Vitamin D plus trace minerals Zinc, Manganese and Copper, which are integral co-factors for several enzymes involved in bone metabolism."


      I am hoping what Twin Labs says is correct: that the combination helps the calcium be absorbed in our systems getting to the bones where it needs to be.
