Vitamins and Nutraceuticals During Pregnancy
According to the American College of Obstetricians and Gynecologists (ACOG), it is advisable to take one prenatal vitamin a day. This typically includes:
- Vitamin C (80 mg for ages 14-18, 85 mg for ages 19-50)
- Calcium (1300 mg for ages 14-18, 1000 mg for ages 19-50)
- Vitamin A (750 mg for ages 14-18, 770 mg for ages 19-50)
- Vitamin D3: 400-600 units
- B6: 1.9 mg
- B12: 2.6 mg
- Folic Acid: 600 mg
- Iron: 27 mg
- Choline: 450 mg
Supplements such as B1 (1.4 mg), B2 (1.4 mg), B3 (18-35mg), and zinc (11-13 mg) are recommended by the American Pregnancy Association.
Magnesium supplementation during pregnancy may reduce fetal growth restriction and pre‐eclampsia and increase birthweight. (See below for dosing.) The need for magnesium increases during pregnancy, and most pregnant women likely do not meet this increased need. Magnesium deficiency or insufficiency during pregnancy may pose a health risk for both the mother and the newborn, with implications that may extend into adulthood of the offspring.
Vitamin C, D3, zinc, and B complex
Taken within recommended daily dose, are considered safe in pregnancy since they are part of recommended prenatal vitamin supplementations.
Magnesium and Omega-3 fatty acids (mercury-free source): Safe and Beneficial
A daily dose of 300-400 mg magnesium is safe and beneficial in pregnancy.[3;4] Data derived from observational studies have found that omega-3 fatty acid consumption during pregnancy either in the diet or via supplements is associated with improved neurodevelopmental outcomes in the child.
(600 mg daily) appears to be safe in pregnancy. [6;7]
