Iced coffee contains the same caffeine as hot coffee. A typical 16oz iced coffee has 150-200mg caffeine. ACOG recommends limiting caffeine to 200mg per day during pregnancy. Cold brew tends to have more caffeine than regular iced coffee.
A "Use Caution" rating means this food is generally fine during pregnancy but comes with a specific factor worth managing — a daily limit, a preparation requirement, or a moderation guideline — rather than a reason to avoid it outright. These ratings reflect general guidance from the FDA, ACOG, CDC, and USDA. The goal of the "caution" label is to flag what to pay attention to, not to suggest the food is unsafe when that factor is properly managed.
