Creatine is a well-studied and popular supplement known for enhancing athletic performance and muscle growth. Here are some of the key points regarding its benefits and uses:

1. Exercise Performance and Muscle Strength:

   • Creatine has been shown to improve performance in high-intensity, short-duration activities such as weightlifting and sprinting¹²³.
   • Supplementation can lead to increases in muscle strength and fat-free mass when combined with resistance training⁴⁵.
   • It is also effective in increasing muscle creatine and phosphocreatine stores, enhancing the body's ability to regenerate ATP (adenosine triphosphate), which is crucial for prolonged high-intensity activity³.

2. Recovery and Muscle Damage:

   • Creatine supplementation may help reduce muscle damage and accelerate recovery after intense exercise³⁶.

3. Cognitive and Brain Health:

   • Studies suggest that creatine may benefit brain function. It has been shown to improve cognitive performance in stressful situations and memory in vegetarians and the elderly⁷⁸.
   • There is preliminary evidence indicating its potential role in treating neurological conditions such as Alzheimer's disease, Parkinson's disease, and depression⁸⁹.

4. Safety and Dosing:

   • Short-term use of creatine is generally considered safe with minimal adverse effects¹¹⁰.
   • Common dosing regimens include an initial loading phase of 20 grams per day for 5-7 days, followed by a maintenance dose of 3-5 grams per day¹⁵.
   • Creatine is allowed by major sports committees, including the International Olympic Committee and NCAA³.

Creatine's potential benefits extend beyond athletic performance, making it a versatile supplement for various populations. However, the long-term effects are still under ongoing research, and individuals should consult with healthcare providers before starting supplementation, especially those with pre-existing health conditions.
