What is collagen?

Heard the glowing reports of how collagen can do everything from improving the look of your skin, hair, and nails to boosting your bone and gut health? Yep, collagen is definitely trending. This may make you gasp, but US consumers spent $293M on collagen supplements in 2020 — and its popularity appears to be only on the rise. [1]

So what’s the deal here? Is it worth all the hype? Let’s dive in.

Collagen is a protein that occurs naturally in our bodies. It has all sorts of jobs, from keeping our skin smooth and supple to supporting our bones, cartilage, and connective tissue. In fact, collagen is so important (and abundant) in our bodies that, as this study reveals, as much as a third of the protein in our bodies is made up of it. [2]

Our natural collagen production actually peaks in young adulthood and slowly starts to decline from around our thirties. This drop becomes more noticeable during perimenopause and menopause, when falling oestrogen levels affect how much collagen the body can make. And not having enough naturally occurring collagen — called endogenous collagen — in our bodies is linked to a few different health conditions, including the now-rare disease scurvy. [3]

As we age, collagen production decreases. And one of the most noticeable effects of this is the change in our skin’s elasticity. [4]

(Sidebar: we’re all for the beauty of laugh lines. But we also know that it’s totally okay to seek out younger-looking skin. You do you.)

Enter collagen peptides — tiny pieces of protein made from animal collagen that can help your body recover its lost collagen. Collagen peptides come in all sorts of forms — pills, powder, drinks, and creams, as well as dermal fillers that can be injected into your skin. [5]

In fact, the colorless, tasteless powders that can be popped into smoothies or your favorite drink are also a particular hit.

What are the benefits of collagen?

The research looks promising on this one. This 2019 review of oral collagen supplements showed that they had a positive impact on skin elasticity and wound healing. [6]

And this 2018 study exploring the use of collagen to improve bone mineral density in postmenopausal women was also really promising. [7]

And a 2025 study showed how collagen supplemented with vitamin D and calcium may also help increase muscle strength and improve bone mineral density in older adults. [8,9]

So yes, overall, there seems to be a reason for all the fuss. But, like all supplements, collagen products are not regulated by the FDA. [10]

And the use of collagen during pregnancy is not well studied. Let’s take a look.

Is collagen safe in pregnancy?

Very little research on this gives a definite answer, but from what we know, collagen appears to be safe during pregnancy. Before loading up that shopping cart, though, know that not all collagen products are created equal.

The two most common sources of collagen are bovine collagen (from cows) and marine collagen (from fish). The general rule? Stick to the cow.

That’s because there’s a chance that marine collagen could bring you into contact with some other fishy pregnancy issues. While fish can form an essential part of your pregnancy diet — so much so that the USDA recommends eating between 8 and 12 ounces per week — there are some risks associated with it.

Fish collagen is made from fish cartilage and scales, which may come with some risks when pregnant. There are no regulations around the types of fish used in these products, so there’s a chance that they could have a high mercury content or contain other toxic substances. And this could be harmful to both you and your developing baby. [11]

On the other hand, bovine collagen is heat-treated (by boiling the bones and other byproducts of cattle) and hydrolyzed — a process that helps remove bacteria and makes it safe as a dietary protein source. Because collagen supplements are regulated as dietary supplements in the US (not as medicines), it’s smart to look for brands that have third-party testing or quality certifications to reduce contamination risks.

Is collagen powder safe during pregnancy?

Collagen powder — usually made from hydrolyzed bovine collagen — is generally considered safe to use during pregnancy. It’s essentially a source of protein, and studies haven’t shown any harmful effects. That said, research specifically focused on pregnant women is limited, so it’s best to check in with your healthcare provider before adding it to your routine.

Is collagen peptides safe during pregnancy?

Collagen peptides are simply smaller pieces of collagen protein that your body breaks down into amino acids. They’re widely used and are generally recognized as safe, but there isn’t much research looking at their effects in pregnancy. The overall risk appears low, though it’s always smart to get your provider’s go-ahead first.

Is marine collagen safe during pregnancy?

Marine collagen — made from fish skin or scales — is where a little more caution is needed. Some products may contain traces of heavy metals or other pollutants, depending on how and where the fish were sourced. Because supplement quality can vary a lot, it’s best to stick to well-tested brands or choose bovine collagen instead, and always talk to your doctor before using marine-based products while pregnant.

Is collagen good to take while pregnant?

While getting the protein you need is important during pregnancy — 75 to 100 grams a day is recommended — there’s no evidence to suggest that you need to take collagen at this time. [12]

Plus, since collagen is not a complete source of protein, you can still meet your protein intake from a balanced diet that includes foods like eggs, lean meat, dairy, legumes, and nuts. But if you want to take collagen, it’s a good idea to run it by your healthcare provider. Talk to them about the specific product you’d like to take.

Different products have different ingredient lists — so it might be a good idea to run it by them to see if your product of choice contains anything that could be harmful to you right now. Some pregnant people take collagen to prevent or treat stretch marks, but as the American Academy of Dermatologists tells us, it may not be that simple. [13]

While we know that stretch marks are caused by a rupture of the collagen and elastin in our skin, we just don’t know whether collagen supplements can prevent this from happening. It’s also worth remembering that your body naturally adjusts collagen production during pregnancy to help your skin and tissues stretch — a process that’s complex and influenced by hormones, genetics, and hydration, not just by what you eat.

How much collagen is safe during pregnancy?

While there are no specific regulations around this, a typical dose for healthy adults is between 2.5 and 10 grams. [14]

But again, it’s important to check in with your doctor about an appropriate dose for you. If you’re not keen to go down the supplement route, several healthy foods contain collagen, including poultry, fish, pork, red meat, dairy, and eggs.

You can also make an animal bone broth by simmering bones in water and a bit of vinegar for between 4 and 24 hours.

And for vegetarians, there are options here too. While plants don’t make collagen, they do help your body make it. Foods that contain zinc and vitamin C are particularly good for this, so adding leafy greens, nuts, broccoli, and berries to your diet is a win. And these can be great additions to your pregnancy diet anyway.

(As a guide, the American College of Obstetricians and Gynecologists (ACOG) recommends getting 85 milligrams of vitamin C if you’re over the age of 19.) [15]

Collagen and pregnancy: the bottom line

While collagen peptides show much promise as a supplement to a healthy diet, the research is still young. Talk to your doctor to see if they’re a good idea for you and your unique pregnancy.
