DIETARY GUIDELINES FOR Americans
The Dietary Guidelines for Americans (DGAs) addressed caffeine for the first time in 2015. In late 2020, the 2020–2025 Dietary Guidelines for Americans were released and addressed caffeine again. The new guidelines did not change the current recommendation of up to 400mg/day for healthy adults. However, the Guidelines were expanded to include recommendations for healthy pregnant and lactating women. As caffeine passes from a mother to her infant in small amounts through breast milk, the Guidelines suggest that healthy pregnant lactating women can safely consume low to moderate amounts (about 300 milligrams or less per day, which is about two to three cups of coffee). Women are encouraged to talk with their healthcare provider about consuming caffeine during pregnancy or while lactating.
