Is creatine really just for muscle? Creatine is a naturally occurring compound involved in the body's energy production system, and it's not a steroid or stimulant. Research in older adults suggests that creatine can be a useful adjunct to resistance training, with evidence for modest improvements in muscle strength. Its effects on muscle mass and physical function are less certain. Researchers are also studying creatine for brain-related outcomes such as cognition, mood, and mental fatigue, but those potential benefits are still being investigated. And what about the kidney concern? Recent reviews suggest creatine can cause a small increase in serum creatinine, which doesn't necessarily mean kidney damage. However, anyone with existing kidney disease should talk with their healthcare professional before using creatine. The bigger takeaway? Creatine may have a much broader role in health conversations than its reputation suggests. 💬 What's the biggest reason you'd consider creatine: strength, muscle maintenance, energy, or curiosity? #creatine #creatinemonohydrate #musclehealth #healthyaging #strengthtraining #womenshealth #menopausehealth #brainhealth #supplements #fitnessover50 - @drdavidmorris
