How It Works

Fueling the Body’s Energy System

Creatine is a naturally occurring compound stored primarily in muscle tissue and also in the brain. Its primary role is to support the regeneration of ATP, the molecule responsible for delivering energy at the cellular level.

When creatine stores are sufficient, the body can more efficiently produce energy during short, repeated, or demanding efforts. This supports physical output, endurance across repeated movement, and resilience under physical stress.

Because creatine also plays a role in brain energy metabolism, its benefits are not limited to physical performance. Adequate creatine availability can support mental output, focus, and performance during cognitively demanding tasks.

Unlike stimulants, creatine does not force energy or override natural systems. It supports the system that produces energy in the first place.

Captiva Creatine works quietly in the background, helping the body and mind perform at a higher level through consistency rather than intensity.
