The capsule version of Ultra Preventive III contains half the dose amount per serving compared to the tablets. Studies show that a high percentage of adults and children in North America and other developed countries eat less than the minimum daily allowance of 10 or more essential nutrients. Adequate amounts and proper balance of these nutrients are needed not only for maintaining good health, but also for the dietary management. Ultra Preventive® III has been carefully developed to contain all the essential vitamins, minerals, and trace elements. Each ingredient is selected in consideration of its absorbability, competitive relationship with other nutrients and allergenic potential. Certain nutrients such as beta-carotene, vitamin C, vitamin D, vitamin E, B-complex vitamins and specific minerals are included in high-potency amounts because of the vital roles they play in antioxidant protection, immune support, energy production and maintenance of healthy blood cells, nervous system, hormonal balance, and more. Minerals and trace elements are provided in their safest and most bioavailable forms, such as amino acid chelates and other scientifically validated and clinically superior forms. Additional vitamin D3 (also known as cholecalciferol) has been added to this formula as numerous scientists now feel that supplementation with vitamin D at levels greater than previously thought necessary is critical to helping maintain overall health.
