Pregnancy has a way of turning e ven the simplest supplement choice into a research project. Collagen is a good example. It's everywhere in skincare and wellness circles, and plenty of expectant mothers wonder whether it's worth adding in or whether it belongs on the same cautious list as retinoids and high-dose vitamin A.
For those already leaning toward organic pregnancy products and cleaner sourcing, understanding collagen's safety profile is one of the first important steps.
What Collagen Actually Does in the Body
Collagen is the body’s most abundant structural protein, the foundation of skin, joints, tendons and connective tissue. Your body makes it spontaneously from amino acids like glycine and proline.
In pregnancy, the body needs more protein to help the baby grow and to stretch the skin and ligaments in a short space of time. This combination is why collagen has gained popularity among pregnant women, evolving from a basic anti-ageing vitamin.
Why protein needs increase during pregnancy
Most guidelines say that pregnant women require a lot more protein than normal, typically between 70 and 100 grams a day in the second and third trimesters, to maintain the placenta and the growing tissue of the baby.
However, collagen alone won’t hit that aim, as it doesn’t include certain important amino acids, which are in a complete protein source. Therefore, it’s better to see it as one contributor in a well-rounded diet, rather than a substitute for meat, fish, dairy or pulses.
Is It Actually Safe? What Research and Experts Say
What the evidence shows so far
The short answer from most obstetricians and pharmacists is yes, collagen is generally considered safe during pregnancy when taken as directed. It's a food-derived protein rather than a hormone or active drug, and it's chemically similar to protein you'd obtain from bone broth or gelatine.
A more honest and detailed response is that there are limited dedicated clinical trials involving pregnant women. Most of what we know comes from research in the general adult population, plus a reasonable understanding of collagen's basic biology, rather than large-scale studies specifically confirming benefit or risk during pregnancy.
The one ingredient to watch: vitamin A
The key safety signal isn’t collagen itself; it’s what is occasionally put along with it. Some collagen blends also include retinol or high-dose vitamin A for skin advantages, and excess vitamin A is one of the few supplement ingredients that the NHS specifically cautions against in pregnancy, as there is a relationship with birth abnormalities at high dosages.
Don’t only look for the term 'collagen' on the front of the tub; always examine the entire list of ingredients. It’s the safer, easier option of a plain hydrolysed collagen peptide product without retinol or extraneous additions.
Joint and ligament comfort
Relaxin is a hormone that loosens ligaments during pregnancy to prepare for labour. And this is partly why joint aches and pelvic pain are more common in late pregnancy.
Some pregnant women take collagen in the hope that it will help with joint aches, and there is a reasonable physiologic explanation why it could be beneficial. But this is still an area of thin, primarily anecdotal evidence.
Choosing Organic Pregnancy Products and Cleaner Sourcing
This situation is where good sourcing really counts. By selecting organic pregnancy products and collagen that has been third-party tested instead of a blend that isn’t confirmed or is loaded with additives, you minimise your risk of exposure to contaminants and unwanted extras you don’t need while pregnant.
Marine collagen is often excellent for those who avoid red meat, whereas bovine collagen has a more diverse collagen type spectrum. Neither is necessarily safer than the other; it is more about the sourcing and testing standards behind the individual product than the animal it originated from.
A note on allergies
Marine collagen is derived from fish; therefore, it’s not a good choice for anyone with a fish or shellfish allergy regardless of how it’s promoted.
Bovine collagen has a substantially lower chance of cross-reactivity for individuals with a beef or gelatine sensitivity. Just as important as looking for additional vitamin A is looking at the source on the label.

How Much Collagen Is Considered Reasonable
Most advice recommends between 2.5 and 10 grams of hydrolysed collagen peptides a day – very much in the range of a normal dish of bone broth or a typical scoop of supplement.
You should not exceed that amount in the hope of achieving better results. In this context, consuming more collagen is not beneficial, and a reasonable, food-based strategy is typically the most practical option throughout pregnancy.
Getting collagen from food rather than a tub
Bone broth, slow-cooked meat with the connective tissue left in, and fish skin all contain naturally occurring collagen, though the amount varies far more than a measured supplement dose.
Timing and how to take it
Collagen peptides dissolve readily in hot or cold drinks and don’t have much of a flavour, so you can easily add them to a morning drink or a glass of water.
Vitamin C is a necessary cofactor in the process; therefore, collagen combined with a source of vitamin C, such as citrus fruit or peppers, might promote the body’s own collagen production.
FAQs
Is marine collagen better than bovine collagen in pregnancy?
Neither one is intrinsically safer. Marine collagen is suitable for a pescatarian diet and generally simple to digest, while bovine collagen provides a broader spectrum of collagen types. Usually the decision is based on food preference rather than pregnancy-specific safety.
Should I check with my GP before starting collagen?
Yes. Before starting any new supplement in pregnancy, especially a prenatal vitamin, it's wise to check with your GP to see if there's any overlap or personal reason it might not be suitable.
Does collagen interact with prenatal vitamins?
Collagen is a protein, not a vitamin or mineral; thus, it does not fight for absorption like calcium and iron can often do. Most individuals take it with a conventional prenatal vitamin with no problem, but it is worth discussing with your midwife.
A Sensible and Informed Choice
Most specialists would tell you collagen is not in the same warning category as retinoids or uncontrolled herbal mixes and is a reasonable addition from dietary sources during pregnancy.
The true protection isn’t the collagen itself; it’s the sourcing behind it. Selecting organic pregnancy products and reviewing the entire ingredient list for vitamin A, followed by a consultation with your midwife, will significantly enhance your peace of mind compared to the marketing claims of any single tub.
