Summary
Vitamins A and D can be toxic at high levels, meaning it can be dangerous to greatly exceed recommended daily intake. Some vitamin-fortified foods have 100 percent of the daily intake of both vitamins. Many people overestimate what counts as a serving of these foods. Many people will consume two to three times the manufacturer-defined serving size.
Strongly Supported Conclusions
Some people who eat vitamin-fortified food are exceeding the recommended daily intake of vitamins A and D by eating two to three times the serving size.

This is strongly supported because we are told that some people exceed more than one serving of these foods daily, and each serving can contain 100 percent of the recommended daily levels of vitamins A and D.
