How Do I Know If I’m Getting Enough Nutrients During Pregnancy?

12 Jan 2026

Pregnancy changes everything—including your nutritional needs. But with symptoms, food aversions, and shifting guidance, it can be hard to tell whether you're truly getting what your body and baby need.

This guide helps you understand:

  • The signs of nutrient deficiencies in pregnancy
  • The role of supplements
  • When and how to get tested
  • What to do if you’re falling short

Why Nutrient Monitoring Matters In Pregnancy

Your baby draws what they need directly from you. If your levels drop too low, it can:

Knowing your nutritional status can help you take targeted action—rather than relying on guesswork.

“Pregnancy is one of the most nutritionally demanding stages of life. It’s not about taking more—it’s about taking what’s right for you. Testing allows us to tailor support, protecting both maternal health and baby’s development.” Professor Mark Johnson, Consultant Obstetrician and Founder of Nurture

Signs You Might Not Be Getting Enough

While blood tests are the most reliable way to know, certain symptoms can offer early clues.

Nutrient   Possible Signs of Deficiency
Iron Fatigue, breathlessness, pale skin, headaches
Folate/B12 Low energy, brain fog, irritability, mouth sores
Vitamin D Low mood, muscle weakness, increased illness
Omega-3 DHA Poor memory, low mood, dry skin, visual changes
Magnesium Muscle cramps, poor sleep, irritability
Iodine Dry skin, weight gain, feeling cold, sluggishness
Choline Brain fog, low focus, early fatigue (though hard to detect early)


⚠️ Important: These signs don’t always mean you have a deficiency — they can often be a normal part of pregnancy or simply day-to-day life. Most of the time, they’re nothing to worry about, but if you’re ever unsure, or if something doesn’t feel right, it’s always best to check in with your doctor or midwife for reassurance and tailored advice.

Should I Get My Nutrient Levels Tested?

These symptoms can overlap with common pregnancy side effects, so it's not always obvious. That’s where blood testing can help. Should you get your nutrient levels tested? Yes—especially if:

  • You follow a vegetarian, vegan, or restricted diet
  • You’ve had pregnancy complications in the past
  • You’re taking supplements but still feel off
  • You want peace of mind

Which Nutrients Can Be Tested?

At-home or clinical blood tests can check levels of:

  • Iron (ferritin)
  • Vitamin D (Nurture offers dedicated Vitamin D testing)
  • Vitamin B12
  • Folate
  • Omega-3 (DHA & EPA levels) — Nurture provides DHA testing, and subscribers to the NurtureBundle receive two FREE DHA tests
  • Magnesium (in some tests)
  • CRP (inflammation)
  • Thyroid function (TSH, T3, T4) – related to iodine and overall metabolism

Nurture’s at-home blood test kits are designed to monitor key nutrients in pregnancy—offering real insights and tailored supplement guidance.

What If I’m Not Getting Enough?

If a test shows you’re low in a particular nutrient:

  • Adjust your supplement – Make sure your supplements contain clinically effective doses of the nutrient you’re lacking.
  • Add nutrient-rich foods – Including food sources can support better absorption and help restore levels naturally.
  • Retest regularly – Your needs can change as pregnancy progresses, so regular testing helps you stay on track.
  • Follow medical advice for deficiencies – Some nutrients, like iron or vitamin D, may require higher short-term doses under the guidance of your healthcare provider.

Can I Have Too Much Of A Nutrient?

Yes—some vitamins and minerals (especially vitamin A, iodine, and iron) can be harmful in excess. Always choose supplements formulated for pregnancy, and avoid “stacking” products unless advised by a healthcare professional.
