Can I Take Collagen During Pregnancy?

Pregnancy is a time when every supplement you consider feels more important than ever and that includes collagen. With many women turning to collagen for its skin, joint, and hair benefits, it's natural to wonder: Can I take collagen during pregnancy?

Let’s look at the facts, explore potential risks and benefits, and help you make a confident decision.

What Is Collagen, and Why Do People Take It?

Collagen is the most abundant protein in the human body, found in the skin, bones, joints and connective tissues. Many people take collagen supplements (NHS) — usually in powder, capsule, or liquid form - to support:

• Skin elasticity and hydration

• Hair and nail strength

• Joint and ligament health

• Gut lining integrity

During pregnancy, these benefits can be especially appealing as your body undergoes so many physical changes.

Is It Safe to Take Collagen While Pregnant?

There is no conclusive evidence suggesting collagen is unsafe during pregnancy, and many healthcare professionals see it as a relatively low-risk supplement — provided it’s pure and well-sourced.

However, as research is still limited, it's best to speak to your midwife or GP before starting any new supplements during pregnancy.

Potential Benefits of Collagen During Pregnancy

Skin Support
Collagen can help maintain skin elasticity and may reduce the appearance of stretch marks as your bump grows.

Joint Comfort
Pregnancy hormones loosen your joints, which can lead to discomfort. Collagen may help support joint health and mobility.

Hair and Nail Strength
Many women report postpartum hair thinning. Collagen may support healthy hair and nail growth before and after birth.

Gut Health
Some research links collagen with gut health benefits,  potentially helpful for mums experiencing reflux, nausea or bloating.

Are There Any Risks?

While collagen itself is typically safe, the ingredients included in some supplements can pose risks during pregnancy. Look out for:

• Vitamin A (retinol) - should be avoided in high doses. The NHS warns that too much vitamin A can harm your baby's development.

• Artificial sweeteners -which some prefer to avoid during pregnancy.

• Herbal extracts - some may not be safe for pregnancy, so always check labels.

To stay safe, choose a clean, unflavoured collagen supplement with minimal ingredients and no added vitamins unless approved by your doctor.

What to Look For in a Collagen Supplement

When buying collagen during pregnancy, look for:

• Third-party tested supplements for quality and safety

• No added vitamin A or synthetic additives

• Sourced from marine or grass-fed bovine collagen

• No artificial flavourings or sweeteners

Examples of clean, UK-available collagen brands include:

• Bare Biology Skinful Marine Collagen (no added extras, sustainably sourced)

• Vital Proteins Collagen Peptides (widely available in the UK, unflavoured option)

Always double-check the label and consult your midwife or GP before choosing any supplement.

What Do UK Experts Say?

The NHS doesn’t list collagen as a concern during pregnancy, but they do advise against certain nutrients in excess, like vitamin A.

Most midwives and nutritionists agree:

"It’s likely safe if it’s clean and simple, but always check with your GP first, especially if you're already taking other supplements."

When to Avoid Collagen

Avoid collagen supplements during pregnancy if:

• They contain vitamin A/retinol, or herbal extracts not approved for pregnancy

• You have allergies to the source (e.g. fish or beef)

• You notice unusual side effects or gastrointestinal upset

Final Thoughts: Should You Take Collagen While Pregnant?

For many mums-to-be, collagen is a helpful, safe addition to your wellness routine, particularly for supporting skin and joint health. The key is choosing a high-quality, pregnancy-safe brand, and getting the go-ahead from your healthcare provider.
