Pregnancy is an exciting, transformative time but also brings a whirlwind of decisions. From choosing the right prenatal vitamins to maintaining a balanced diet, ensuring the safety of everything you consume becomes a top priority. One common supplement that often sparks curiosity is collagen. Pregnant women may wonder, “Is collagen safe during pregnancy?” If you’ve found yourself asking this question, you’re not alone.
This comprehensive guide will explore collagen’s safety, benefits, and potential risks during pregnancy, helping you make an informed decision for you and your baby. We’ll also cover which types of collagen are best, how they can support your health, and whether they’re safe to take with prenatal vitamins. Let’s dive in!
Is Collagen Safe During Pregnancy? Understanding the Basics

Collagen is the most abundant protein in your body, playing a vital role in skin, joints, bones, and connective tissues. As you navigate through pregnancy, many women consider supplementing their diets with collagen to support skin elasticity, joint health, and overall well-being.
The good news is that collagen is generally considered safe during pregnancy, but there are essential factors to consider before incorporating it into your routine. According to the American Pregnancy Association, collagen supplements are unlikely to pose a risk when taken in moderation and from reputable sources.
Supporting Evidence: A study published in the Journal of Clinical Medicine (2020) highlighted that hydrolyzed collagen peptides are well-tolerated during pregnancy and could benefit the skin and connective tissues. However, it cautioned that more clinical studies are needed for conclusive evidence.
Collagen is found in hydrolyzed collagen, collagen peptides, and gelatin. These forms are all derived from animal sources such as bovine, chicken, or marine life (fish). For pregnant women, it’s essential to choose high-quality, clean supplements free from harmful additives and contaminants. Additionally, you should consult your healthcare provider before starting any new supplement, including collagen, to ensure it’s appropriate for your unique health needs.
Key Considerations:
- Choose reputable brands: Look for third-party tested products with natural ingredients and certifications to ensure quality.
- Consult your doctor: Especially if you have allergies or underlying health conditions.
Which Collagen Supplement Is Best for Pregnancy?
Not all collagen is created equal when selecting a collagen supplement during pregnancy. The three main types of collagen supplements—bovine collagen, marine collagen, and chicken collagen—each offer unique benefits. Let’s break them down:
Collagen Type | Source | Best For | Considerations |
Bovine Collagen | Cows (skin, bones) | Skin, joints, and bones | High-quality option; make sure it’s grass-fed and hormone-free. |
Marine Collagen | Fish (skin, scales) | Skin elasticity and hydration | Check for contamination (heavy metals); avoid if allergic to seafood. |
Chicken Collagen | Poultry (cartilage) | Joints, skin, and tendons | Suitable for joint support, opt for hydrolyzed chicken collagen. |
Supporting Evidence: According to research published in Nutrients (2018), bovine collagen is often recommended for its abundance of type I collagen, which benefits skin and bone health. While highly bioavailable, Marine collagen is noted for its potential contamination risk from heavy metals.
Which Is the Best Choice for You?
- Bovine Collagen: Often recommended for pregnancy as it’s generally safe, supports skin elasticity, and may help with joint health.
- Marine Collagen: While it’s highly absorbable, some concerns arise due to potential contamination with heavy metals. You may want to consult your doctor about this option.
- Chicken Collagen: Known for supporting joints, this collagen type is a good alternative if you are sensitive to bovine or marine sources.
You can enjoy the benefits of choosing a high-quality collagen supplement without compromising your safety or your baby’s.
Can You Take Collagen While Trying to Conceive?
If you’re trying to conceive, you might wonder whether collagen supplementation could impact fertility. While collagen is not known explicitly for boosting fertility, it can support your overall health, which is crucial when trying to conceive.
Collagen plays a significant role in the strength and elasticity of connective tissues, including the uterus. In fact, collagen’s ability to support the body’s structural integrity may benefit the reproductive system. Additionally, collagen can be beneficial in maintaining a healthy gut, which is essential for hormone balance during the pre-conception phase.
Since there’s no evidence suggesting collagen negatively affects fertility, it’s generally safe to take while trying to conceive. As always, it’s best to consult your healthcare provider before adding new supplements to your routine.

Is Collagen Safe During Pregnancy’s Third Trimester?

The third trimester is a critical time for both you and your baby. At this stage, your body undergoes significant physical changes, including increased strain on your joints, skin, and muscles. This makes collagen supplementation even more beneficial as it may help with skin elasticity and joint support.
Collagen and Skin Elasticity: During pregnancy, your body stretches to accommodate the growing baby, often leading to issues like stretch marks. Collagen can support the skin’s elasticity, potentially reducing the appearance of stretch marks, although results may vary.
Joint Support: As your body weight increases, the pressure on your joints intensifies, making joint discomfort more common in the third trimester. Collagen can provide support for cartilage, potentially easing discomfort.
Despite its benefits, always discuss collagen supplementation with your doctor to ensure it fits into your pregnancy care plan. Your healthcare provider can help determine the safest action if you have any underlying health concerns.
Can Collagen Be Taken Alongside Prenatal Vitamins?
Prenatal vitamins are necessary during pregnancy to ensure you get all the essential nutrients. But what about collagen? Can these two supplements be taken together?
The short answer is yes. Collagen can generally be taken alongside prenatal vitamins without issue. Both provide different benefits: Prenatal vitamins focus on essential nutrients like folic acid, iron, and calcium, while collagen supports skin, joints, and overall health.
In fact, combining collagen with prenatal vitamins may provide a holistic approach to maintaining your skin’s elasticity, joint function, and overall well-being during pregnancy.
What Are the Risks of Taking Collagen While Pregnant?
While collagen is generally safe for most pregnant women, there are a few risks to be mindful of:
- Contaminants in Marine Collagen: Marine collagen, in particular, can sometimes contain harmful heavy metals or allergens. Be sure to choose high-quality, certified marine collagen if you decide to go that route.
- Allergies: Some individuals may have allergic reactions to collagen derived from specific animal sources, such as fish or bovine. Always check ingredient lists carefully and consult your doctor if you have concerns.
- Digestive Issues: While collagen is generally easy to digest, some people may experience mild digestive discomfort, particularly when starting supplementation.
If you experience any unusual symptoms after taking collagen, it’s essential to stop and consult your healthcare provider.
Why Marine Collagen Might Not Be Safe During Pregnancy
Marine collagen has become popular due to its high bioavailability (the ability to be absorbed and utilized by the body). However, concerns regarding its safety during pregnancy are primarily related to heavy metal contamination.
Fish and other marine life can accumulate toxins such as mercury, harming you and your baby. Therefore, if you opt for marine collagen, choose a brand that undergoes rigorous third-party contaminant testing.
If you’re concerned about the risks of marine collagen, you might want to consider other collagen types, such as bovine or chicken collagen, which generally carry fewer risks.
Pregnancy-Safe Collagen Alternatives: Are There Any?
Understanding the Basics – 5 Surprising Facts About Collagen Supplements You Must Know!
For those looking for a non-animal-based option, plant-based collagen alternatives are available. These are typically made from ingredients like vitamin C, silica, and amino acids that support collagen production in the body rather than containing actual collagen. These alternatives are considered safe during pregnancy, but it’s essential to research the brand and ensure the product is high-quality.
Some women might prefer plant-based alternatives if they avoid animal-derived products during pregnancy.
