Top Pregnancy Supplements and Foods for a Healthy Baby and Mom

If you’re pregnant, taking the right supplements is essential to support your health and your baby’s development. If you’re like me and don’t like taking medication unnecessarily, or at least without a logical understanding, this may be worth your five minutes of reading. In this article, I’ll explain the importance of some key supplements and show you which foods naturally contain the same vitamins and nutrients.

1. Prenatal Multivitamin

I’m sure that during your very first appointment, your obstetrician mentioned a prenatal multivitamin.

  • Why? Contains a blend of key vitamins and minerals for both you and the baby.
  • Sources: A prenatal multivitamin is a combination of essential nutrients. While it’s difficult to replicate a prenatal in food form, eating a variety of nutrient-dense foods can help cover many needs:
    • Leafy Greens (spinach, kale): Rich in folate, iron, and magnesium.
    • Eggs: Provide choline, vitamin D, and some folate.
    • Salmon: Excellent for omega-3s, vitamin D, and iodine.
    • Nuts and Seeds (almonds, sunflower seeds): Contain magnesium, vitamin E, and B vitamins.

    Still, a supplement is often needed to ensure you’re meeting daily recommendations.

  • What to look for: Choose one specifically labeled for pregnancy, with folic acid, iron, iodine, and vitamin D.

2. Folic Acid (400–800 mcg daily)

Folic acid is one of the most important supplements to take during pregnancy.

  • Why? It plays a vital role in:
    • Reducing the Risk of Congenital Heart and Brain Defects
      Help lower the chances of structural heart abnormalities in the baby and reduces the risk of neural tube defects (e.g., spina bifida).
    • Supporting Placental Development. It has a crucial role in the formation and function of the placenta, ensuring proper nutrient and oxygen delivery to the baby.
  • Sources: Folic acid in supplements is the synthetic form of folate, which occurs naturally in foods:
    • Spinach, kale, and other dark leafy greens, asparagus, lentils, avocado, citrus fruits (oranges, grapefruits).

     

  • Timing: Start at least 1 month before conception and continue through the first trimester.

3. Iron (27 mg daily)

  • Why? Helps prevent anemia and supports the baby’s development of red blood cells.
  • Sources: Iron comes in two forms:
    • Heme iron (from animal sources, better absorbed).
    • Non-heme iron (from plant sources, absorption improves when eaten with vitamin C).

    Foods rich in iron:

    • Red meat (beef, lamb), chicken and turkey, lentils, cooked spinach, fortified cereals, pumpkin seeds, tofu.

    Tip: Pair with vitamin C-rich foods (e.g., oranges, bell peppers) to enhance absorption. Avoid it with calcium-rich products, as calcium can interfere with iron absorption, reducing its effectiveness.

4. Vitamin D (10–20 mcg or 400–800 IU daily)

  • Why? Supports bone development and immune function for both you and your baby.
  • Sources: Limited in foods, so supplementation and sunlight exposure are often necessary. Foods that provide vitamin D include:
    • Fatty fish (salmon, mackerel, sardines), egg yolks, fortified milk or plant-based milk, fortified orange juice, mushrooms (exposed to UV light).

5. DHA/EPA (Omega-3 Fatty Acids, 200–300 mg daily)

  • Why? DHA and EPA are essential omega-3 fatty acids that support the baby’s brain, eye, and nervous system development, especially in the third trimester when the brain grows rapidly.
  • Help reducing inflammation and may lower the risk of preterm labor or postpartum depression.
  • Sources: Fatty fish like salmon, sardines and mackerel, or fish oil/algae-based supplements for vegetarians/vegans.
  • Tip for Pregnancy: Look for purified fish oil supplements to avoid mercury and contaminants.

6. Calcium (1,000 mg daily)

  • Why? Essential for the baby’s bones, teeth, and muscles, as well as maintaining the mother’s bone density. If the diet lacks calcium, the body will take it from the mother’s bones, increasing the risk of osteoporosis.
  • Sources: Dairy products (milk, yogurt, cheese), fortified plant-based milk, tofu, leafy greens like kale, and almonds.
  • Tip for Pregnancy: Absorption improves when taken alongside vitamin D, which is often included in prenatal vitamins.

7. Iodine (150–220 mcg daily)

  • Why? Supports thyroid function, brain development, and metabolism. Deficiency can lead to hypothyroidism, developmental delays, or goiter in both the mother and baby.
  • Sources: Iodized salt, seafood (like cod), dairy products, and eggs.
  • Tip for Pregnancy: Avoid iodine excess, as it can also disrupt thyroid function. Stick to prenatal vitamins with the recommended dosage.

8. Magnesium (350–400 mg daily)

  • Why? Helps with relaxing muscles, preventing leg cramps, and supporting nerve function. It also helps regulate blood pressure, reducing the risk of preeclampsia, and promotes healthy bone and teeth formation.
  • Sources: Nuts (almonds, cashews), seeds (pumpkin, sunflower), whole grains, spinach and avocado.
  • Tip for Pregnancy: Some magnesium supplements, like magnesium citrate, can also help relieve constipation.

9. Vitamin B6 (10–25 mg daily)

  • Why? Helps with the formation of red blood cells and supports the development of the baby’s brain and nervous system.
  • It’s particularly useful in reducing nausea and vomiting in early pregnancy.
  • Sources: Bananas, potatoes, chicken, salmon, fortified cereals, and nuts.
  • Tip for Pregnancy: Small, regular doses throughout the day can help combat morning sickness.

10. Probiotics (Optional)

  • Why? Probiotics promote a healthy gut microbiome, reducing pregnancy-related issues like constipation, bloating, and diarrhea. They may also improve maternal immunity and potentially reduce the risk of gestational diabetes and vaginal infections (e.g., yeast infections).
  • Sources: Yogurt, kefir, sauerkraut, kimchi, miso, and probiotic supplements.
  • Tip for Pregnancy: Choose strains proven safe during pregnancy, such as Lactobacillus and Bifidobacterium.

Things to Avoid:

  • Vitamin A in high doses: Can be toxic to the baby. Stick to what’s in your prenatal.
  • Herbal supplements unless approved by your healthcare provider.

Ensuring you get the right nutrients during pregnancy is one of the best things you can do for both your health and your baby’s development. While some supplements are essential, combining them with a balanced diet rich in nutrient-dense foods can make a big difference. Always consult your healthcare provider to adjust your supplement routine to your specific needs, and remember: every healthy choice you make brings you one step closer to welcoming your baby into the world.
