Optimal nutrition support for our client begins before she even conceives. Birth control pills make it difficult for women to absorb some nutrients that are essential for a healthy pregnancy. Ideally, women who were previously on birth control pills will deplete those nutrients before conception.

Nutrients that are not well absorbed while women are on birth control pills include folate, vitamins B2, B6, and B12, vitamins C and E, coenzyme Q10, magnesium, selenium, and zinc (Palmery, Saraceno, Vaiarelli, & Carlomagno, 2013) (Palan, Strube, Letko, Sadikovic, & Mikhail, 2010).

Antidepressants, which are commonly prescribed to women of childbearing age also deplete folate.

Non-steroidal anti-inflammatory drugs (NSAIDs), including ibuprofen, can irritate the intestinal lining increasing the requirement for zinc and amino acids and can suppress ovulation in the short term (Duffy, 2015).  Thus, a woman who has been on these medications prior to trying to conceive needs to focus on optimizing her nutrient intake.

Taking a high-quality prenatal vitamin is an important step.

Additionally, taking prenatal vitamins has well-established benefits for babies regardless of the specific ingredients or quality of the prenatal supplement, including…

  • Lowering the risk for leukemia (Leung et al., 2013).
  • Lowering the risk for pediatric brain tumors (Leung et al., 2013)
  • Lowering the risk for neuroblastoma (Leung et al., 2013).
  • And, lowering the risk for a number of congenital anomalies cardiovascular defects, 
limb defects, urinary tract anomalies, cleft palate, and neural tube defects (Leung et al., 2013).

In other studies, specific benefits have been found for specific nutrients being at optimal levels for baby’s development and childhood health, and for maternal health during and after pregnancy.

Vitamin D

Mothers of children with early childhood dental cavities had significantly lower vitamin D levels, measured by 25(OH)D levels (Schroth et al., 2014). Those mothers with an average of 40nmol/L vitamin D level vs. those with an average of 52nmol/L vitamin D level had babies with more cavities (Schroth et al., 2014).

Nearly half of pregnant women have deficient (less than 30 nmol/L), or insufficient (30-49 nmol/L) vitamin D status at mid-pregnancy, and 82% are deficient or insufficient at birth (Ozias et al., 2014). Typical supplementation of vitamin D from average prenatal vitamins (approximately 334 IU/day) is not enough to restore adequate vitamin D status in pregnant women. The variables that are important are the 25(OH)D level in mid-pregnancy and the season of birth. Women who delivered in summer and fall had a 1.5-fold greater plasma 25(OH)D concentration than women who delivered in winter in spring (41.1 +/- 23.1 and 40.7 +/- 20.5 nmol/L summer and fall, respectively, versus 27.7 +/- 17.9 and 29.3 +/- 21.4 nmol/L in winter and spring, respectively).

Adequate vitamin D supplementation prior to pregnancy or at least by mid-pregnancy is essential. Higher levels of maternal vitamin D correlate with birth weight, infant calcium levels, and infant bone mass (Harvey et al., 2014).

I recommend that women have their 25(OH)D levels assessed prior to pregnancy and/or in early pregnancy. Adequate vitamin D levels are rare in women of childbearing age who spend much of their time indoors or wearing sunscreen. Vitamin D is necessary throughout pregnancy and for nursing mothers, but it’s nearly impossible for nursing mothers to have enough vitamin D to pass along through their breast milk unless they are supplementing in the range of 5,000 – 6,000 IU/day (Creighton University, 2014).

Omega-3 Fatty Acids

Women who took omega-3 fatty acid supplements (fish oil) showed decreased risk of postpartum depression on the Edinburgh Postnatal Depression Scale (EPDS) (Leung et al., 2013). At least 200mg-300mg per day of omega-3 fatty acid intake is ideal for pregnant women for other reasons as well, such as increasing gestation length, reducing the risk of preterm birth, and improving fetal brain development including infant cognitive and visual performance and even reversing some of the neurological effects of fetal alcohol syndrome (Jordan, 2010) (Patten, Sickmann, Dyer, Innis, & Christie, 2013).

Vitamins C and E

Vitamins C and E are essential antioxidants for pregnant women and their babies. Supplementing with vitamins C and E is associated with a reduction in placental abruption and preterm birth among mothers who smoke (Abramovici et al., 2014). Obviously, I don’t recommend smoking during pregnancy, but for this high-risk population and others with antioxidant depletion, such as mothers who were previously on birth control, I recommend supplementing with antioxidants, including vitamins C and E to potentially reduce the risks of preterm birth and placental abruption.

Additionally, adequate vitamin C levels can protect fetal brains from the increase in oxidative stress that occurs during pregnancy (Ahn, Kim, Park, Park, & Lee, 2007) (Paidi, Schjoldager, Lykkesfeldt, & Tveden-Nyborg, 2014).

B-Vitamins

Vitamin B6 is a vitamin that is often low in high-risk populations of prenatal women, including those with previous birth control use. Women who were given B6 supplementation reported less nausea, improved appetite, less headache, and less depression as compared with controls (Var, Keller, Tung, Freeland, & Bazzano, 2014).

Folate (Vitamin B9)

In addition to reducing the risk for neural tube defects and other congenital anomalies, healthy maternal folate levels in mid-pregnancy are associated with a decreased risk of lower respiratory tract infections and atopic dermatitis in early childhood (Kim et al., 2015). However, folic acid supplementation may not be as safe as supplementing with the active form of vitamin B9, 5-methyltetrahydrofolate. Synthetic folic acid has been linked to leaving circulating residues in the maternal blood and in fetal cord blood (Choi, Yates, Veysey, Heo, & Lucock, 2014), which can increase colon cancer risk.. Synthetic folic acid is more difficult to metabolize than the active form, 5-methyltetrahydrofolate.

Iron

Fetal memory can be negatively affected by maternal iron deficiency. Supplementing with iron and choline can prevent or improve memory deficits (Kennedy et al., 2014). Prenatal iron is ideally supplemented based on maternal levels. Levels at or below 70 μg/L require some degree of supplementation (Millman, 2011).

Selenium

Women who took selenium supplements showed a decreased risk of postpartum depression on the Edinburgh Postnatal Depression Scale (EPDS) (Leung et al., 2013).   Additionally, women who were thyroid peroxidase antibody-positive who were given 200 mg/ day of selenium supplements had significantly lower rates of hypothyroidism postpartum as compared with the control group who received a placebo (28.6 vs. 48.6%, P<0.01; and 11.7 vs. 20.3%, P<0.01) (Negro et al., 2007).

Zinc

Adding 15 mg of zinc to prenatal vitamins, improved zinc status both for mothers and their infants, but in most it was still lower than recommended values for well-nourished populations (Caulfield, Zavaleta, & Figueroa, 1999).

So… What do I recommend?

The winner is… Seeking Health Prenatal.

While there are many high quality brands of prenatal supplements available for women who are pregnant or planning to conceive, I recommend Seeking Health Prenatal because this supplement is truly evidence based for what women need prior to conception and during pregnancy, postpartum and nursing.

It includes…

  • 2000 IU of vitamin D3 daily.
  • Vitamin E in a highly absorbed form.
  • Vitamin B6 to prevent maternal side effects like nausea.
  • Folate and B12 in their methylated forms, which are better absorbed without leaving residue in the maternal and cord blood circulation.
  • Calcium and magnesium for mother and baby’s bone health, but in heart-healthy ratios.
  • 200 mg of selenium, which is recommended to prevent postnatal hypothyroidism.
  • No Iron, so that it can be personally and selectively dosed to prevent excessive inflammation and constipation.
  • 250 mcg of Choline for optimal fetal brain health and memory.
  • Added anti-oxidants.
  • Added digestive support to make it easier to get this down, especially in it’s protein powder form, for women with prenatal nausea.
  • Blood sugar balancing support.
  • And, I recommend adding 1-2 capsules daily of optimal fish oil to support immune and nervous system health for mom and baby.

In addition to prenatal supplementation, all pregnant women and those trying to conceive need to have at least a basic foundation of healthy nutrition.
