Suggested Use As a dietary supplement, adults take 6 tablets daily with food or as directed by your health professional. More Info. Studies show that a high percentage of adults 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 of the body’s structure as well as the optimum functioning of its various systems. Basic Preventive® 4 has been carefully developed to contain the right proportions of vitamins, minerals, trace elements, and other nutrients for optimal health. Each ingredient is selected in consideration of its absorbability, competitive relationship with other nutrients, allergenic potential, and long-term safety. Certain nutrients such as beta-carotene, vitamin C, vitamin E and B-complex vitamins are included to support the vital roles they play in energy production, antioxidant support 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.
