Many Americans do not get enough essential nutrients such as calcium, potassium, vitamin D, and vitamin B12 in their diets, and a multivitamin supplement can help ensure adequate intake of these nutrients, according to WebMD. Thus, taking a multivitamin supplement can protect against chronic conditions that can develop from vitamin deficiencies. In addition, a daily multivitamin is safer than mixing several individual supplements, which may lead to exceeding the recommended upper limit for a particular nutrient.

Folic acid may also reduce a person's risk for colon cancer, heart disease and breast cancer. In addition, the Vitamin D in a multivitamin also helps decrease colon cancer risk. Among postmenopausal women, taking a daily multivitamin is associated with increased bone density and reduced fractures, according to WebMD.
