Overview
Paper Summary
This study found that creatine supplements may improve muscle recovery after intense exercise, showing better strength recovery and less soreness compared to a placebo. The effect on reducing swelling was particularly notable in women. However, individual responses varied, and factors like diet and hormones weren't strictly controlled, potentially affecting the results.
