# Is Collagen During Pregnancy Safe? What Research Shows
Pregnancy transforms a woman's body in visible ways. Stretched skin, weakened hair, and joint pain become routine complaints. Many pregnant women explore supplements like collagen to address these changes, but the evidence on safety remains mixed.
Collagen is a protein that makes up connective tissue, skin, and bones. During pregnancy, the body's collagen production naturally shifts to support the growing baby and prepare for delivery. Some prenatal nutritionists suggest supplemental collagen may help with skin elasticity, joint support, and hair health during this demanding time.
However, research on collagen supplementation specifically during pregnancy is limited. Most collagen products contain type I and III collagen, often sourced from bovine (beef) or marine (fish) sources. The proteins break down during digestion into amino acids, which the body can use for various functions. This process appears safe, but long-term pregnancy studies remain sparse.
Obstetricians generally advise caution with any supplement during pregnancy. The American College of Obstetricians and Gynecologists (ACOG) recommends discussing new supplements with your healthcare provider first. Some collagen supplements contain additives, sweeteners, or flavorings that warrant individual review.
Pregnant women get collagen naturally through bone broth, gelatin, and protein-rich foods like chicken skin and fish. Vitamin C supports collagen production in the body, and prenatal vitamins already contain this nutrient. Before adding a collagen powder or capsule, pregnant women should confirm the product's purity and consult their doctor about whether it fits their individual health needs.
The safest approach involves discussing collagen with your obstetrician or midwife before starting any supplement. They understand your medical history and can recommend whether collagen makes sense for you. Eating a protein
