Could a daily creatine drink boost postpartum energy and brainpower?
NCT ID NCT07795853
First seen Aug 31, 2026 · Last updated Sep 01, 2026 · Updated 1 time
Summary
Researchers are testing whether taking creatine monohydrate daily for four weeks helps postpartum women improve exercise performance, recover faster after workouts, and sharpen thinking. The trial compares two doses, 5 grams and 10 grams per day, in 40 women who are 6 weeks to 12 months after giving birth. Participants mix the supplement with water, and a small group also undergoes brain scans to measure creatine levels. The goal is to see if this common supplement can ease some of the physical and mental fatigue new mothers often face.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Creatine monohydrate taken daily mixed with water
- What this could lead to
- If it works, creatine could become a simple daily supplement to help new mothers recover from exercise and think more clearly during the postpartum period.
- What could go wrong
- This is a small, early trial with only 40 participants, so results may not apply to all women. Creatine can cause stomach upset or weight gain, and the higher dose may not add extra benefit.
