So, why should every mom expecting twins work with a pregnancy dietitian?
Even if you already know a thing or two about eating healthy, a twin pregnancy is a whole different ballgame. Here are 7 compelling reasons why a registered dietitian who gets twin pregnancy should be your next best friend:
1. Reduce Your Risk of Preterm Birth
Nutrition is a powerful, evidence-based way to support full-term birth in a twin pregnancy. Meeting your calorie and weight gain goals helps ensure your babies are getting the nutrients they need for optimal growth. Babies who thrive in the womb are less likely to be born prematurely.
In fact, women pregnant with twins are generally advised to gain 40–56 pounds, but this range varies based on your pre-pregnancy BMI. A pregnancy dietitian can help you pinpoint your exact weight gain goals and create a realistic plan to meet them.
Specific nutrients can also help to reduce risk of preterm birth. For example, glycine (found in collagen, bone broth, and slow-cooked meats) supports uterine elasticity ultimately reducing risk of uterine over distention. A nutrient-dense diet can support placental health by reducing inflammation and lower your risk of early labor.
Inside the Twice Nourished Nutrition Program, we’ll set up your calorie and nutrient goals and tailor a plan that works for your lifestyle—so you can support full-term growth, one delicious bite at a time.
2. Prevent Common (But Serious) Nutrient Deficiencies
Nutrient deficiencies are far more common in twin pregnancies—and they can lead to serious complications like preeclampsia, anemia, and impaired fetal growth.
Did you know that moms carrying twins need 2x the protein, 1.8x the iron, 1.7x the folate & 2–3x the calcium compared to singleton pregnancies?
The research is quite alarming when it comes to pregnancy risks associated with nutrient deficiency:
Inadequate folate in the first trimester can result in neural tube defects resulting in babies born with parts of their brain, tissue, skull or scalp missing.
Vitamin D deficiency increases mom’s risk of gestational diabetes, preeclampsia, preterm birth and small for gestational age babies.
Complications related to iron deficiency anemia include preterm birth, low birth weight babies, developmental delays and postpartum depression.
Inadequate calcium intake in pregnancy can weaken mom’s bone tissue and increase risk of preeclampsia in pregnancy.
Unfortunately, your one-a-day prenatal vitamin likely isn’t cutting it and that’s where a pregnancy dietitian comes in. We’ll do a full nutrition analysis to identify where your diet might be lacking, and create a personalized plan (including supplement recommendations) to ensure both you and your babies are fully nourished.

3. Get Relief from Twin Pregnancy Symptoms
Twin pregnancies often come with double the symptoms, worse morning sickness, more intense fatigue, and that fun combo of heartburn + zero appetite.
Before you reach for another mystery supplement or Google another “natural morning sickness cure,” let’s chat. A pregnancy dietitian can provide you with real, research-backed strategies for symptom relief without wasting your money or stressing your system. And no, you don’t have to suffer through morning sickness, heartburn, constipation and fatigue in your pregnancy. There are simple strategies that can help!
4. Stop Wading Through Vague or Conflicting Nutrition Advice
When you search “nutrition for twin pregnancy,” most resources tell you the obvious: “Eat more and gain more weight.”
Okay... but how much more should you eat? What’s your exact protein target? What kind of folate is best? Should you eat deli meat or avoid it?
Generic advice just doesn’t cut it in a twin pregnancy. With professional guidance, you get:
Precise answers
Clear strategies
Nutrition that fits your body, babies, and goals
That’s exactly what we provide inside the Twice Nourished Nutrition Program—a complete twin pregnancy nutrition guide, 1:1 support with trained prenatal dietitian and delicious (pregnancy-friendly) recipes.
5. Know Exactly What to Eat (and What to Avoid) Without the Food Fear
Twin pregnancy already comes with enough to worry about, food choices shouldn’t be one of them. Tired of hearing, “I ate that during pregnancy and I was fine,” right after someone else warns you about it? A pregnancy dietitian helps you cut through the noise. You’ll get research-backed food safety guidance, support in making your own educated decisions and clarity on foods to avoid, limit, or enjoy freely so you can stop second-guessing every bite.
6. Access Nutrient-Dense, Twin-Friendly Recipes
By working with a pregnancy dietitian, we can help you create a unique nutrition plan tailored to your food preferences, allergies, cravings and food aversions. Twin pregnancies demand more nutrients—and that means your meals need to work harder for you.

Every recipe is carefully crafted to include key nutrients like folate, iron, calcium, fiber, vitamin D, and protein—so you don’t have to guess or Google.
