What Are the Key Benefits?

Increased Strength & Power

Creatine increases phosphocreatine stores, enabling more ATP production during maximal effort. Meta-analyses show 5-15% strength increases.

Muscle Growth

Promotes muscle hypertrophy through increased training volume and cell volumization. Studies show 2-4 lbs more lean mass over 12 weeks vs placebo.

Cognitive Benefits

Emerging research shows creatine improves short-term memory, processing speed, and reduces mental fatigue, especially under stress or sleep deprivation.

Neuroprotection

May protect against neurological diseases. Animal studies show potential in Parkinson's, Huntington's, and traumatic brain injury models.

What Is It and How Does It Work?

Creatine monohydrate is one of the most researched sports supplements in existence. It naturally occurs in muscle cells and helps produce ATP during heavy lifting and high-intensity exercise. Over 500 peer-reviewed studies support its efficacy and safety.

Frequently Asked Questions

Does creatine cause hair loss?

One 2009 study showed increased DHT, but no study has ever shown actual hair loss. The evidence is weak and contested.

Do I need a loading phase?

No. Loading saturates muscles faster (5-7 days vs 3-4 weeks), but end results are identical. 3-5g daily works fine.

Is creatine safe for kidneys?

Numerous studies in healthy adults show no kidney damage. Those with pre-existing kidney disease should consult a doctor.

Which form is best?

Creatine monohydrate. Every other form (HCL, buffered, micronized) has less evidence and costs more. Monohydrate is 99% bioavailable.
