To provide a nutritional "safety net," patients may be encouraged to take a multivita-min/multimineral supplement that contains

a. specific nutrients which cannot be ob-tained from the food supply in adequate amounts.
b. 100% or less of the Dietary Reference In-takes (DRIs) for most micronutrients.
c. at least 100% of the DRIs for most mi-cronutrients.
d. specific nutrients that are found to be lacking in their diet using dietary analysis.


B
Patients may be encouraged to take a multivitamin/multimineral supplement that contains 100% or less of the DRIs for most micronutrients to help provide a nutritional "safety net.". Most people can obtain sufficient nutrients from food if the diet is carefully planned. Supplementation of amounts exceeding 100% of the DRIs could cause nutrient imbalances or toxicity. Some sub-groups of the population may be advised to consume supplements of specific nutrients, but this type of "safety net" recommendation is based on age, gender, and other factors, rather than indi-vidual nutrient analysis.
