Vitamins & Minerals: The Hidden Heroes Behind Your Energy, Mood & Health

Stop Guessing What Your Body Really Needs

Here is a breakdown of the essential micronutrients your body needs throughout pregnancy and postpartum. You will learn why they are important, the recommended amount, and the top 5 food sources for each.

Iron

Why It’s Important:

Supports red blood cell production, prevents anemia, boosts energy.

Recommended Amount:

18 mg/day (for non-breastfeeding), 9 mg/day (for breastfeeding)

Top 5 Food Sources:
  1. Clams (cooked): 3 oz (28 mg)
  2. Lentils (cooked): 1 cup (6.6 mg)
  3. Spinach (cooked): 1 cup (6.4 mg)
  4. Beef (lean, cooked): 3 oz (2.1 mg)
  5. Tofu (firm): 1/2 cup (~3 mg)

Notes: Heme iron (clams, beef) is more bioavailable than non-heme (lentils, spinach, tofu). Pair plant sources with vitamin C (e.g., bell peppers) to enhance absorption.

Calcium

Why It’s Important:

Supports bone health, muscle function, and milk production.

Recommended Amount:

1,000 mg/day

Top 5 Food Sources:
  1. Sardines (canned, with bones): 3 oz (325 mg)
  2. Greek Yogurt (plain): 1 cup (300 mg)

  4. Almonds (raw): 1/4 cup (75 mg)
  5. Fortified almond milk: 1 cup (~450 mg)

Notes: Dairy and canned fish with bones are top sources. Plant sources (collards, almonds) are less bioavailable. Fortified plant milks are great for vegans.

Vitamin D

Why It’s Important:

Enhances calcium absorption, supports immunity, may reduce depression risk.

Recommended Amount:

600 IU (15 mcg)/day (for non-breastfeeding), 1,000–2,000 IU (for breastfeeding)

Top 5 Food Sources:
  1. Salmon (cooked, wild): 3 oz (600–1,000 IU)
  2. Mackerel (cooked): 3 oz (350 IU)
  3. Tuna (canned in water): 3 oz (150 IU)
  4. Fortified milk: 1 cup (100 IU)
  5. Egg yolks: 2 large (~80 IU)

Notes: Few foods provide enough; sunlight or supplements often needed. Salmon is the richest food source.

Omega-3 (EPA/DHA)

Why It’s Important:

Supports mood, reduces inflammation, aids baby’s brain/eye development.

Recommended Amount:

250–500 mg EPA/DHA (for non-breastfeeding), 1,300 mg total (300 mg EPA/DHA) (for breastfeeding)

Top 5 Food Sources:
  1. Mackerel (cooked): 3 oz (1,200 mg EPA/DHA)
  2. Salmon (cooked, wild): 3 oz (1,200 mg EPA/DHA)
  3. Sardines (canned in oil, drained): 3 oz (700 mg EPA/DHA)
  4. Chia seeds: 2 tbsp (5,000 mg ALA, low conversion)
  5. Flaxseeds (ground): 2 tbsp (~6,400 mg ALA, low conversion)

Notes: Fish provide bioavailable EPA/DHA. ALA from chia/flax has <5–10% conversion to EPA/DHA. Aim for 2–3 fish servings/week.

Why It’s Important:

Supports energy, nerve function, and breast milk quality.

Recommended Amount:

2.4 mcg/day (for non-breastfeeding), 2.8 mcg/day (for breastfeeding)
