Is DHA safe while breastfeeding?
Updated 9 Nov 2026
Short answer
LactMed, the US database on medicines and breastfeeding, gives 250 to 375 mg of DHA and EPA a day as the current advice for nursing mothers.[1] The US FDA considers fish oil up to 3 g a day generally safe as a food.[1]
The DHA in breast milk rises with the dose. In one trial, DHA was 0.21% of the fatty acids in milk with placebo and 1.13% with 1.3 g of DHA a day.[1] With fish oil, the most common complaint is burping with a fishy taste. The smell of breast milk does not change.[1]
