Postpartum Nutrition Guidelines

Core Postpartum Supplementation

The American College of Obstetricians and Gynecologists recommends that all postpartum women continue a comprehensive multivitamin and mineral supplement containing iron (45-60 mg elemental iron daily), vitamin D (≥1000 IU daily), calcium (1200-1500 mg in divided doses), vitamin B12 (1 mg every 3 months IM or 1 mg daily orally), and folic acid (0.4 mg daily) to maintain ferritin within normal limits and prevent deficiencies that can affect both maternal and infant health 1, 2
Women who had adjustable gastric banding may use lower doses of iron (>18 mg) but still require monitoring 1
The Endocrine Society recommends supplementing with vitamin D at ≥1000 IU (40 mcg) daily to maintain serum 25-hydroxyvitamin D levels above 50 nmol/L 1, 3
The National Institutes of Health recommends adding calcium 1200-1500 mg daily in divided doses (including dietary intake) to maintain parathyroid hormone (PTH) within normal limits 1, 2
The American College of Obstetricians and Gynecologists recommends continuing vitamin B12 supplementation at 1 mg intramuscular injection every 3 months or 1 mg daily orally, though oral absorption may be reduced 1, 2
The Academy of Nutrition and Dietetics recommends continuing folic acid 0.4 mg daily postpartum, particularly during breastfeeding 1
Women with obesity (BMI >30) or diabetes should continue higher doses of 4-5 mg daily of folic acid 1, 4

The World Health Organization recommends that women who are breastfeeding require close nutritional monitoring with additional supplements prescribed when necessary to prevent micronutrient deficiencies that can cause adverse maternal and neonatal outcomes 2
The American Academy of Pediatrics recommends breastfeeding for at least 6 months and should be supported with appropriate nutritional supplementation 2
The National Institutes of Health recommends thiamine >12 mg daily for breastfeeding women 1, 5
The Endocrine Society recommends copper 2 mg daily (>1 mg after adjustable gastric banding) for breastfeeding women 1
The Academy of Nutrition and Dietetics recommends zinc 8-15 mg per 1 mg copper for breastfeeding women 1
The American College of Obstetricians and Gynecologists recommends selenium 50 μg daily for breastfeeding women 1, 2
The National Institutes of Health recommends vitamin E 15 mg daily for breastfeeding women 1
The Endocrine Society recommends vitamin A 5000 IU daily in beta-carotene form (avoid retinol form) for breastfeeding women 1, 6
The American Academy of Pediatrics recommends vitamin K 90-120 μg daily, with 10 mg weekly orally if deficiency is noted for breastfeeding women 1, 5

The American College of Obstetricians and Gynecologists recommends checking every 3 months during early postpartum/breastfeeding period: full blood count, serum ferritin, iron studies (including transferrin saturation), serum folate, serum vitamin B12 1, 5
The National Institutes of Health recommends checking every 6 months: prothrombin time/INR, serum vitamin D with calcium/phosphate/magnesium/PTH, serum protein and albumin, liver function tests, serum vitamin E, zinc, copper, and selenium 1, 2

The American Society for Metabolic and Bariatric Surgery recommends that women with history of bariatric surgery require intensive monitoring and higher supplementation doses due to malabsorption 4, 6
The Endocrine Society recommends that women with malabsorptive procedures (RYGB, BPD/DS) are at higher risk for fat-soluble vitamin deficiencies (A, E, K) and require specialist center follow-up 4, 6
The Academy of Nutrition and Dietetics recommends that nutritional status should be closely monitored during lactation with supplements adjusted based on serum levels for women with history of bariatric surgery 2, 6
The American College of Obstetricians and Gynecologists recommends that women with BMI >30 kg/m² should continue higher folic acid doses (4-5 mg daily) postpartum 1, 4

The American College of Obstetricians and Gynecologists recommends not discontinuing supplementation immediately postpartum, as nutritional demands remain elevated, especially during breastfeeding 2
The National Institutes of Health recommends not using vitamin A in retinol form; only beta-carotene form should be used to avoid toxicity risk 1, 6
