What it is
Creatine is a compound your body produces naturally and stores mainly in muscle, where it helps regenerate energy during short, high-intensity effort — think lifting, sprinting, or explosive movement.
Why people look into it
It's one of the most researched supplements in sports nutrition, which is why it comes up for people focused on strength or muscle goals. It's not just for competitive athletes — plenty of everyday gym-goers use it too.
What the research generally says
Creatine is broadly considered one of the better-studied and more consistently effective supplements for supporting strength and power performance, particularly alongside resistance training. Individual response varies.
How people typically approach it
There are different approaches to how much and how often, and personal factors (kidney health, current medications, other conditions) matter. This is a conversation worth having with a healthcare professional rather than guessing.

Want this applied to you?
Coach factors your goals, routine, and what you're already doing into what it suggests — instead of general guidance like the above.
