Answer
The FDA limits folic acid in supplements to 400 micrograms to prevent large amounts from masking iron deficiency.
Solution
The correct answer is: **Large amounts of folate can mask an iron deficiency.**
Folic acid is a synthetic form of folate, and while it is essential for various bodily functions, excessive intake can lead to certain health issues. One significant concern is that high levels of folate can mask the symptoms of vitamin B12 deficiency, which can lead to neurological damage if not addressed.
The FDA limits the amount of folic acid in supplements to 400 micrograms to help prevent these potential health risks while still providing enough for the general population's needs.

Taking large amounts of folate, especially in synthetic forms like folic acid, can interfere with the body's ability to absorb and utilize other important nutrients, such as iron. This can result in an iron deficiency that might go unnoticed, which is particularly concerning for populations at risk, like pregnant women. In addition to nutrient interactions, excessive folate can contribute to health issues, especially in those with undiagnosed vitamin B12 deficiency. This can lead to neurological problems and other complications. Therefore, the FDA has set this limit to help prevent such adverse effects while still allowing for adequate supplementation.
