What Is Relaxin Hormone?
Relaxin Hormone is a peptide hormone linked with pregnancy and reproductive processes. During pregnancy, the body produces relaxin to affect connective tissues, including ligaments around the pelvis. These changes can support pelvic adaptation, but they may also influence joint stability, posture, and movement comfort as pregnancy progresses.

Key Takeaways About Relaxin Hormone
- Relaxin mainly affects connective tissue during pregnancy.
- Ligament changes may influence pelvic stability and movement.
- Relaxin is not the same as a muscle relaxant.
How Relaxin Hormone Works
Relaxin Hormone is produced by the body during reproductive processes, with levels commonly associated with pregnancy. The hormone affects connective tissue by changing how some ligaments and other soft tissues respond to movement. These effects can be especially relevant around the pelvis, where joint support and motion may change as pregnancy develops.

Relaxin does not directly loosen every joint in the body, and its effects differ among individuals. A prenatal assessment considers the person’s stage of pregnancy, symptoms, posture, and movement patterns. The sacroiliac joint and lumbar spine may receive attention because pelvic changes can alter how forces travel through the lower back and hips. Relaxin is also distinct from a muscle relaxant, which is a medication used to reduce muscle tension.
From the Arrowhead Clinic Chiropractor Marietta team
When we provide Prenatal Chiropractic Care, we consider pregnancy-related changes in ligament support alongside posture, movement, and reported comfort. We use that context to guide gentle, pregnancy-appropriate care and avoid treating relaxin as a diagnosis or as a medication.
Relaxin Hormone in Practice: A Real-World Example
A pregnant patient may notice pelvic discomfort when turning in bed or walking because pregnancy-related tissue changes can affect joint support. Prenatal Chiropractic Care may assess movement around the pelvis and lower back while accounting for those changes.
