Pregnancy Supplements: Everything You Need To Know

Pregnancy is an exciting journey filled with many questions—especially when it comes to your health and nutrition. One of the most common is: What pregnancy supplements should I take, and why? And there are so many myths that surround the answer, that we debunk throughout this guide and in our: Pregnancy Supplement Myths: What You Need to Know article. 

This guide will help you understand the role of pregnancy supplements, why they matter, and how to choose the right ones to support both you and your baby—every step of the way.

Why Do You Need Pregnancy Supplements?

During pregnancy, your body works overtime to support the growth and development of your baby. This increased demand means you need more of certain nutrients than usual. While a balanced diet is essential, it can be challenging to meet these higher nutritional needs through food alone.

As Professor Mark Johnson, Consultant Obstetrician and Founder of Nurture, explains:

"I see many women who are doing all the right things—eating well, staying active, looking after themselves—yet they’re still deficient in key nutrients. Pregnancy increases your nutritional requirements, and supplements help bridge the gap to protect both maternal and fetal health. A good quality supplement with clinically effective levels of ingredients can make all the difference."

Pregnancy supplements help to fill these nutritional gaps by providing key vitamins, minerals, and other nutrients in the right amounts to help:

• Support your baby’s brain, bone, and organ development
• Reduce the risk of birth defects and pregnancy complications
• Maintain your energy, immune health, and emotional wellbeing

What Are Pregnancy Supplements?

Pregnancy supplements come in many forms—tablets, capsules, powders, and drinks—designed specifically to support your body during this time. They often include:

• Prenatal vitamins and minerals like folate, iron, calcium, and vitamin D
• Specialty nutrients such as omega-3 DHA, choline, and probiotics
• Sometimes additional support like herbal extracts (when safe) or gentle digestive aids

Why Diet Might Not Be Enough Alone

We’re often told that a healthy diet is all you need—but that’s not always the full picture. Soil depletion, dietary restrictions, morning sickness, and increased physiological demands can make it difficult to reach optimal levels of key nutrients.

For example, Omega-3 DHA is mainly found in oily fish—but many pregnant women avoid fish due to concerns about mercury. Similarly, folate and iron are abundant in leafy greens, but absorption varies and intake may be inconsistent.

When And How To Take Pregnancy Supplements

Ideally, before you’re even pregnant. The first few weeks of pregnancy—often before many women realise they’re expecting—are when key developmental milestones happen.

That’s why experts recommend taking a high-quality prenatal supplement from the moment you start trying to conceive. But if you’re already pregnant and haven’t started, don’t worry—it’s never too late to support your body and baby.

Are All Supplements Safe?

Not all supplements are created equal. Some contain levels that are too low to be effective, while others may include unnecessary ingredients.

Avoid products that contain:

• High-dose Vitamin A (retinol): Can be toxic in excess.
• Unregulated herbal blends: Not always safe or tested in pregnancy.

Check for products that are third-party tested, backed by clinical evidence, and tailored to your unique needs of pregnancy.

How To Choose The Right Pregnancy Supplements

Choosing the right pregnancy supplement can feel overwhelming. Here's what to look for:

• Doctor-formulated or clinically backed products designed specifically for pregnancy.
  
• Bioavailable forms of nutrients for better absorption and fewer side effects (e.g., methylated folate, iron bisglycinate).
  
• Clinically effective dosages—not too low, not excessive.
  
• No harmful additives or excess vitamin A in retinol form.
  
• Extras that support you and your baby, like DHA or Choline.

What About The Cost?

You might wonder if higher cost equals higher quality. Not always—but more often than not there is a reason behind the price tag. High-quality supplements may include better bioavailable ingredients, clinically effective dosages, and rigorous testing for safety.

The Role Of Nutrient Testing

Every pregnancy is different. Gentle, at-home nutrient testing (like Nurture offers) helps identify key deficiencies—like vitamin D or DHA—so you can take exactly what you need, and nothing you don’t.
