Overall, the vitamin and mineral needs of people who are physically active are similar to the requirements for all healthy people.
If dietary intakes are adequate (ie, meet 70% or more of the DRI for nutrients), supplementation is unnecessary.
Sweat losses may require some people to consume higher amounts of some micronutrients, quantities that can be obtained with a varied diet of properly selected foods.
Supplementation may be necessary when intake is inadequate or there is a deficiency in status. Care must be taken so that people do not exceed the UL, which could impair exercise performance and health.
