Can You Take Collagen While Breastfeeding? A Dietitian Explains

Many postpartum moms I work with are curious about collagen—and for good reason. Maybe you’ve noticed more hair in the shower drain, your joints are aching after carrying your baby all day, or your skin feels looser than it used to. Collagen often comes up in postpartum Facebook groups and influencer reels, but there’s a lot of mixed messaging out there.

So let’s break it down, clearly and simply. Here’s what you actually need to know about collagen in the postpartum period—without the fluff or fear-mongering.

💡What Is Collagen, and Why Is It So Popular?

Collagen is a structural protein that makes up a large part of your skin, hair, nails, joints, and connective tissue. Think of it as the glue that holds your body together.

During pregnancy and postpartum, your body goes through massive changes that can impact collagen levels. Many moms look to collagen to help with:

• Hair shedding after birth

• Stretch marks or loose skin

• Joint pain from repetitive movements (like nursing or carrying your baby)

Because of these benefits, collagen has become a go-to supplement for postpartum recovery.

🍼 Is Collagen Safe While Breastfeeding?

The short answer: Generally, yes—but the quality of the product matters.

While there isn’t extensive research on collagen specifically during breastfeeding, there’s also no evidence showing it’s harmful. Collagen is simply a form of protein, and protein-based supplements tend to be lower risk for nursing moms.

That said, it’s always best to:

• Choose high-quality, third-party tested products

• Avoid formulas with added sweeteners or unnecessary fillers

• Talk to your doctor, especially if you or your baby have allergies or underlying health concerns

⚖️ Potential Benefits of Collagen for Postpartum Moms

While collagen isn’t a magic pill, it can support your recovery in several ways:

• Healthier hair and nails: Many moms notice stronger regrowth after the initial postpartum shedding phase.

• Skin elasticity: Collagen may support skin recovery, especially if you’re noticing stretch marks or loose skin.

• Joint support: Helpful if you're frequently lifting or baby-wearing.
  

Gut health: Some types, like hydrolyzed collagen peptides, can support gut lining repair, which may be helpful after a C-section or digestive issues.

🛑 What to Look Out For in Collagen Supplements

Not all collagen powders are created equal. Here’s what to avoid—and what to look for:

Avoid:

• Artificial sweeteners or flavors

• Proprietary blends with unclear sourcing

• Supplements that aren’t third-party tested

Look for:

• Hydrolyzed collagen peptides (easier to absorb)

• Unflavored or clean-label products with minimal ingredients

• Brands that are third-party tested for quality and purity

🧬 How Collagen Fits into a Postpartum Nutrition Plan

Remember: collagen is a supplement, not a replacement for real food. It can support your recovery, but it’s not a stand-alone fix.

I always recommend starting with a food-first approach. This is where the PFF Method—prioritizing protein, fat, and fiber—comes in. Collagen can be a great addition for boosting protein, especially in easy snacks and meals like:

• Smoothies

• Coffee or tea

• Overnight oats

• Soups

One thing to note: collagen provides only specific amino acids. So it’s still important to eat a variety of full-protein sources (like eggs, chicken, lentils, etc.) throughout the day.

Bonus tip: Collagen often contains only certain amino acids → still need full protein from food

❓ Frequently Asked Questions About Collagen & Breastfeeding

Use collapsible Q&A or a simple bullet list:

• Will collagen affect my milk supply?
  There’s no evidence that it harms milk supply. In fact, getting enough protein overall supports healthy milk production.

• Can collagen help with postpartum hair loss?
  It may help support regrowth by providing the building blocks for keratin and stronger hair structure.

• What type of collagen is best while breastfeeding?
  Look for hydrolyzed collagen peptides from a clean, third-party tested source.

• Is marine collagen safe postpartum?
  Generally, yes—if it’s high quality and tested for heavy metals. Always check with your provider if you have a shellfish allergy.

• Should I wait until I’m done breastfeeding?
  Not necessarily. Many moms safely use collagen while breastfeeding, especially when choosing high-quality brands.

• Does collagen count toward my protein intake?
  Yes, collagen can count toward your overall daily protein intake—as long as it’s not your only protein source. It’s not a complete protein (meaning it doesn’t contain all essential amino acids), so it’s important to get a variety of full protein sources from food like eggs, poultry, fish, tofu, lentils, and Greek yogurt.

🧃 How to Add Collagen to Your Daily Routine

It doesn’t need to be complicated. Start with 1–2 scoops a day and see how your body responds. You can:

• Stir it into coffee or tea (unflavored blends work best)

• Add to a smoothie with fruit and healthy fats

• Mix into overnight oats or soups
