Creatine Supplementation: Benefits, Risks, and Scientific Insights
What Is Creatine?
Creatine is a nitrogenous organic acid naturally synthesized in the body from arginine, glycine, and methionine. It plays a vital role in energy metabolism, particularly in muscle and brain tissue. The most studied and widely used form is creatine monohydrate (CrM).
✅ Scientifically Backed Benefits of Creatine
1. Athletic Performance
· Enhances short bursts of anaerobic activity (e.g., sprinting, weightlifting).
· Increases muscle phosphocreatine stores, improving rapid energy availability.
· May support faster recovery post-exercise due to increased glycogen storage.
2. Cognitive Function
· Supplementation increases brain ATP levels and cerebral oxygenation.
· Shown to improve cognitive performance, especially in older adults and during sleep deprivation.
3. Muscle and Bone Health
· Helps offset age-related sarcopenia (muscle loss).
· Supports lean body mass and bone mineral content in adolescents and older adults.
4. General Health
· Low dietary creatine intake is linked to:
o Higher body fat percentage
o Increased risk of depression and cognitive decline
o Greater incidence of liver conditions and angina.
⚠️ Risks and Considerations
1. �� Overconsumption
· Bolus doses >5g may cause gastrointestinal distress (bloating, diarrhea).
· Excessive intake can stress kidneys, especially in individuals with pre-existing kidney conditions.
2. Supplement Quality
· Creatine supplements are not tightly regulated by the FDA.
· Risk of contamination or inaccurate labeling—choose third-party tested products.
3. �� Water Retention
· Initial weight gain due to fluid retention is common but temporary.
