Quick answer

NIH gives 1,300 mcg RAE of vitamin A a day while breastfeeding for women 19 and older, and an upper limit of 3,000 mcg for preformed vitamin A. It reports that experts advise lactating women not to take more than 3,000 mcg RAE (10,000 IU) a day from supplements.1,2

Key facts

  • The vitamin A amount while breastfeeding is 1,300 mcg RAE a day for women 19 and older, and 1,200 mcg for teens.1,2
  • The upper limit for preformed vitamin A is 3,000 mcg a day for adults, 2,800 mcg for teens 14 to 18, and it applies while breastfeeding.1
  • NIH says breast milk from mothers with enough vitamin A covers a baby's needs for the first 6 months.1
  • A Cochrane review of 14 trials gave postpartum women single or double doses of 200,000 to 400,000 IU and found breast milk retinol rose, with no clear difference in infant adverse outcomes.3

What NIH says about vitamin A while nursing

NIH handles pregnancy and breastfeeding together for the high-dose caution. Its consumer sheet says anyone who is or might be pregnant or breastfeeding should not take high-dose supplements of preformed vitamin A, and the health professional sheet says experts advise lactating women not to take more than 3,000 mcg RAE (10,000 IU) of vitamin A daily as supplements.1,2

Women 19 and older need 700 mcg RAE a day, 770 mcg RAE during pregnancy and 1,300 mcg RAE while breastfeeding.1,2

The upper limit for preformed vitamin A is 3,000 mcg a day for adults 19 and older, including in pregnancy and while breastfeeding, and 2,800 mcg for teens 14 to 18. It counts food, drinks and supplements, and it is lower for children: 600 mcg up to age 3, 900 mcg at 4 to 8 and 1,700 mcg at 9 to 13. The limits do not apply to people taking vitamin A under a doctor's care. No upper limit is set for beta-carotene, but the Food and Nutrition Board advises against beta-carotene supplements for the general population except as a source of vitamin A.1,2

Breast milk from mothers who get enough vitamin A covers a baby's vitamin A needs for the first 6 months.1

What do trials of vitamin A in nursing mothers show?

A Cochrane review pooled 14 trials with 25,758 mother and infant pairs. The mothers were given a single or double dose of 200,000 to 400,000 IU of vitamin A, or 7.8 mg of beta-carotene daily. Using NIH's conversion of 0.3 mcg RAE per IU, 200,000 IU is about 60,000 mcg RAE, far above the 3,000 mcg a day upper limit, and NIH says the limits do not apply to vitamin A given under a doctor's care.1,3

Breast milk retinol rose by 0.20 µmol/L at three to three and a half months, on low-quality evidence. The review did not find evidence that vitamin A reduced the mothers' deaths or the infants' deaths.3

On harms the review reported low-quality evidence. The review found insufficient evidence that vitamin A increases abdominal pain, with a risk ratio of 1.28 (0.95 to 1.73). An infant bulging fontanelle at 24 to 48 hours was numerically higher with vitamin A, with a risk ratio of 2.00 (0.61 to 6.55). Both ranges include no difference, so the review could not say either way.3

These trials gave single or double high doses, a different pattern from a daily supplement, but they are the clearest trial data on harms in nursing mothers and infants that the sources checked contain.3

What about vitamin A creams and serums while nursing?

The sources on this page cover vitamin A taken by mouth. They do not report on creams, serums or other skin products used by a nursing mother, which is not a finding either way.1

One related caution comes from MedlinePlus: babies and children are more sensitive to vitamin A, and swallowing products that contain it, such as skin cream with retinol, can cause vitamin A poisoning. A pharmacist can say whether a product is likely to reach a baby's mouth.4

Who should ask a doctor about vitamin A while breastfeeding

  • Nursing mothers who take a vitamin A, fish liver oil or multivitamin product, who should ask their doctor or pharmacist how much preformed vitamin A it holds and whether other products add to it.1
  • Mothers taking isotretinoin or another retinoid medicine, who should ask their pharmacist about breastfeeding.5
  • Mothers of babies who were born early or have a medical condition, who should ask the baby's doctor before any supplement.
