Creatine, a naturally occurring compound synthesized in the liver, kidneys, and pancreas from amino acids like glycine, arginine, and methionine, plays a pivotal role in cellular energy production. Primarily stored in skeletal muscles (about 95%), with smaller amounts in the brain, heart, and other organs, it is converted to phosphocreatine, which rapidly regenerates adenosine triphosphate (ATP) during high-energy demands. This mechanism supports intense physical activity, cardiac function, and neural processes, making creatine essential for tissues under stress.
Dr. Mehdi Boroujerdi, a pharmaceutical researcher, highlights in his review from the Handbook of Creatine and Creatinine In Vivo Kinetics that creatine is not a steroid but an energy facilitator, debunking common myths. For Indian doctors, this is particularly relevant given the high prevalence of vegetarian diets in the population, which often result in lower baseline creatine levels, potentially amplifying supplementation benefits. Emerging research suggests creatine’s anti-inflammatory and antioxidant properties could extend to therapeutic applications, including neuroprotection in Parkinson’s disease, mood enhancement in depression, and mitigation of muscle and bone loss during menopause or aging—areas of growing concern in India’s aging demographic and rising mental health challenges.
Supplementation, typically with creatine monohydrate, involves a loading phase of 20 grams daily (divided doses) for 5-7 days, followed by 3-5 grams maintenance, though gradual dosing achieves similar saturation. Factors like carbohydrate co-ingestion enhance absorption, while individual responses vary by age, sex, diet, and muscle mass—women and vegetarians often showing greater gains. Safety profiles are robust for healthy individuals, with no evidence of kidney damage in those without pre-existing conditions, though consultation is advised. However, creatine is not a panacea; it doesn’t directly build muscle or exceed saturation limits, with excess excreted as creatinine. Dr. Boroujerdi calls for more human studies using labeled creatine to clarify kinetics, especially in clinical settings.
For Indian healthcare professionals, integrating creatine could support preventive strategies in general health, neurology, and geriatrics, potentially positioning it as an over-the-counter therapeutic amid India’s focus on affordable, evidence-based interventions. While promising for cognitive function, athletic performance, and chronic conditions, rigorous trials are needed to substantiate broader applications.
