Overview
Collagen supplements have grown popular among pregnant women for supporting skin elasticity, joint comfort, and hair health. As a structural protein, collagen makes up much of the body's connective tissue. During pregnancy, demand for protein increases by about 25 grams daily according to the National Academies of Sciences. However, specific data on supplemental collagen remains limited.
Safety Details
Collagen peptides are derived from animal sources and hydrolyzed for better absorption. They do not appear to cross the placenta in ways that cause fetal harm based on available pharmacokinetic studies. No FDA warnings exist specifically for collagen in pregnancy, and it is generally recognized as safe (GRAS) for food use. That said, ACOG has not issued formal guidelines, and peer-reviewed trials in pregnant populations are sparse. Potential concerns include heavy metal contamination in some marine or bovine products, which could theoretically affect development.
Trimester Guide
First trimester: Focus on whole-food protein sources rather than supplements, as nausea may make powders unappealing. Limit to under 10g daily if used.

Second trimester: Up to 15g daily may be considered for skin support as the belly grows, provided the product is third-party tested.
Third trimester: Some women increase to 20g for joint relief, but monitor total protein intake to avoid exceeding 100g daily without medical advice.
Alternatives/Tips
- Consume bone broth or gelatin-rich foods for natural collagen.
- Choose prenatal vitamins with vitamin C to boost natural collagen production.
- Opt for hydrolyzed collagen from grass-fed sources with NSF or USP certification.
- Pair with vitamin C-rich foods like citrus to enhance absorption.
When to Consult Your Doctor
Always discuss collagen use with your OB-GYN before starting, especially if you have kidney concerns or follow a vegetarian diet. Bloodwork can confirm protein levels and rule out contaminants.
