Does creatine stop your muscles from breaking down?
Effects of acute creatine monohydrate supplementation on leucine kinetics and mixed-muscle protein synthesis.

Surprising Findings
Creatine reduced protein breakdown in men but not women, despite identical dosing and training conditions.
Most assume creatine works the same across sexes; this shows a clear biological difference in how men and women metabolize protein under supplementation.
Practical Takeaways
Men considering creatine for muscle preservation during cutting phases may benefit from its anticatabolic effect, while women might need to focus on other strategies.

Taking creatine helps your muscle cells soak up more water, making them swell a bit—and this swelling tells your body to stop breaking down muscle as much.
Taking creatine for a week may help men’s bodies use less of a key protein building block during workouts, but it doesn’t seem to do the same for women—so the effect might be different by sex.
Taking creatine for a week like this doesn’t make you weigh more or gain more muscle in young, healthy men and women.
Taking creatine for a week may lower protein breakdown in young men by about 7.5%, but it doesn’t seem to have the same effect in young women.
Taking creatine for a week doesn’t make your muscles start building protein faster, even if you take a lot of it at first and then less later.
