Creatine is stored in muscles and used as a quick source of energy during short bursts of intense physical activity. By increasing the creatine phosphate stores in muscles, supplementation helps in rapid ATP regeneration, allowing individuals to sustain higher levels of power and performance during activities like weightlifting, sprinting, and high-intensity interval training.
Beyond its role in muscular energy metabolism, creatine has attracted attention for its potential neuroprotective effects. The brain is an energy-demanding organ, and creatine’s influence on ATP production may support cognitive functions. Studies have explored its impact on conditions like traumatic brain injury, neurodegenerative diseases, and mental fatigue, with some promising findings.
Moreover, creatine has been linked to increased water content in muscle cells, which may contribute to muscle hydration and growth. This osmotic effect can create an environment conducive to protein synthesis and cell volumization, potentially aiding in muscle hypertrophy.
Despite its generally positive safety profile, it’s crucial to note that individual responses to creatine supplementation may vary. Side effects are usually mild, such as gastrointestinal discomfort or water retention, but consulting with a healthcare professional is advisable, especially if you have pre-existing health conditions or concerns. They can provide personalized guidance based on your health status and fitness goals.
