Which of the following is considered an excessive intake of folate?

600 mcg
2,000 mcg
400 mcg
1,000 mcg

The correct answer is: 2,000 mcg

The recommended dietary allowance (RDA) for folate varies depending on age, sex, and life stage, but for adults, it is generally around 400 mcg per day. Higher levels, such as 600 mcg, are typically recommended for pregnant women to support fetal development. When considering excessive intake, the Tolerable Upper Intake Level (UL) for folate supplements and fortified foods is set at 1,000 mcg for adults. Consuming folate above this level, especially from supplements rather than food sources, can mask vitamin B12 deficiency and potentially lead to neurological complications. Therefore, an intake of 2,000 mcg of folate exceeds this upper limit, making it an excessive amount for adults, which can pose health risks and reflect the potential for adverse effects from high levels of supplementation. Consequently, this amount is classified as excessive compared to the established guidelines.
