Role in Cellular Metabolism
Creatine is pivotal in energy metabolism, particularly in muscle and brain cells. It functions in conjunction with creatine kinase to regenerate adenosine triphosphate (ATP), the primary energy carrier in cells, during periods of high energy demand7. This process is essential for maintaining energy homeostasis, especially during intense physical activities.
Creatine Supplementation in Sports
Creatine supplementation has become increasingly popular among athletes for its potential to enhance performance in short-duration, high-intensity activities. Studies have shown that creatine can improve muscle strength, power, and overall exercise performance3 5. However, its effectiveness in endurance sports remains inconclusive5.
Health and Therapeutic Benefits
Beyond its use in sports, creatine has been studied for its potential therapeutic benefits in various health conditions. Research indicates that creatine supplementation can improve muscle strength and functional performance in individuals with muscular dystrophies and idiopathic inflammatory myopathies2 4. Additionally, creatine has shown promise in managing conditions such as statin myopathy, treatment-resistant depression, and sarcopenia in the elderly4.
Safety and Dosage
Short-term creatine supplementation is generally considered safe and well-tolerated, with few reported adverse effects3 5. Common dosing regimens include a loading phase of 20-30 grams per day for 5-7 days, followed by a maintenance dose of 2-5 grams per day5. However, the safety of long-term use, particularly in children and adolescents, requires further investigation3.
