Collagen has become a go-to supplement for everything from glowing skin to joint health. Whether it’s stirred into coffee, mixed into smoothies, or blended into post-workout shakes, collagen peptides are now a wellness staple. But with growing popularity comes more questions—and one that keeps popping up is: can collagen cause constipation?
If you’ve recently added collagen to your routine and noticed some digestive discomfort, you’re not alone. Constipation is a frequently mentioned side effect among new users, especially when trying collagen for the first time.
In this post, we’ll explore whether collagen can actually contribute to constipation, why it may happen, and what you can do to avoid it while still enjoying all the benefits.
What Is Collagen and Why Are So Many People Taking It?
Collagen is the most abundant protein in the human body. It’s a major component of connective tissue, skin, tendons, cartilage, and bones. As we age, natural collagen production decreases—which is why many people supplement to support:
- Skin elasticity and hydration
- Joint flexibility and mobility
- Hair and nail growth
- Gut and bone health
Hydrolyzed collagen peptides (the most common form in powders) are designed for easy absorption. They’re tasteless, dissolve easily, and are widely used for beauty, fitness, and overall wellness.
So… Can Collagen Cause Constipation?
Let’s get straight to it—can collagen cause constipation? The short answer is: yes, in some people, particularly when first starting out.
Here’s why it might happen:
1. Lack of Fiber in the Supplement
Collagen powders are pure protein and typically contain zero fiber. If you’re not compensating with enough fiber in your diet, it can slow down your digestion.
2. Sudden Increase in Protein Intake
For some, a sudden boost in protein can slow the digestive system. Especially if you’re taking collagen in addition to other protein-rich foods or supplements, your gut may react by reducing motility.
3. Not Drinking Enough Water
Collagen absorbs water during digestion. Without enough hydration, the body may not process it efficiently—leading to harder stools and slower bowel movements.
4. Other Ingredients in Collagen Supplements
Some brands include binders, fillers, or flavoring agents that may irritate the gut or contribute to constipation. Always read the label.

Signs That Collagen Might Be Affecting Your Digestion
If you’ve recently added collagen and are experiencing the following, the supplement might be the cause:
- Decreased bowel movement frequency
- Feeling bloated or overly full
- Hard or dry stools
- Mild abdominal cramping
If you haven’t changed much else in your diet, collagen is a potential factor to consider.
How to Prevent Constipation When Taking Collagen
Here’s the good news: most cases of collagen-related constipation are temporary and manageable. Here are some ways to minimize or prevent it:
✅ Start Slow – Begin with half a serving and increase gradually over a week.
✅ Drink More Water – Aim for at least 8–10 cups daily, especially when taking collagen.
✅ Boost Your Fiber – Add fruits, veggies, or a fiber supplement alongside your collagen.
✅ Choose Clean Formulas – Avoid collagen powders with added sugars, gums, or artificial flavors.
✅ Add to Meals – Incorporating collagen into meals can ease digestion vs. taking it alone.
Does Everyone Experience This?
No—many people take collagen regularly with zero digestive issues. It often depends on your gut sensitivity, hydration levels, and the balance of your overall diet.
Some users even report better digestion and fewer gut issues with collagen, particularly if they had inflammation or a leaky gut prior.
When to Be Concerned
If constipation lasts more than a few days or is accompanied by other symptoms like severe bloating, nausea, or discomfort, it’s best to pause the supplement and consult your healthcare provider.
You may also want to try a different brand or form—collagen from marine sources or with added digestive enzymes might suit your body better.
Final Thoughts
So, can collagen cause constipation? Yes, but it’s usually temporary and preventable. For most people, the benefits of collagen far outweigh any minor side effects—and a few simple adjustments can make a world of difference.
The key is listening to your body. Stay hydrated, keep your fiber intake in check, and don’t be afraid to experiment with timing and dosage. If you’re looking for more guidance or scientific insight, this comprehensive review has everything you need to feel confident in your collagen journey.
