I believe creatine is beneficial for everyone. It’s one of the most scientifically validated supplements. It’s safe and effective. In addition to its fitness advantages, it has been demonstrated to promote cognitive function, cardiovascular health, and potentially aid in recovery from traumatic brain injury.
A consideration is that starting creatine while already losing weight can lead to some weight gain. This is because it causes water retention throughout your body, particularly in your muscle cells.
Although the weight gain won't be substantial, some increase is expected as you initially load it and reach effective levels.
Also, some individuals may experience stomach discomfort when using creatine. I didn't used to, but I do now that I'm taking GLP-1 medications.
I should clarify that I dose my creatine at 20mg daily, which is beyond what's needed for muscle and fitness, aiming for cognitive benefits. Standard dosing is 5-10mg per day for fitness purposes.
