Enhanced Absorption and Safety of MuscleBlaze CreAMP™: A Comparative Analysis With Regular Micronized Creatine Monohydrate in Healthy Male Adults

Background Creatine monohydrate is a widely utilized dietary supplement in sports nutrition, valued for its role in enhancing muscle energy availability, power output, and performance during high-intensity, short-duration activities. Creatine monohydrate is effective but limited by absorption inefficiencies and side effects. Enhanced forms can improve uptake, reduce gastrointestinal discomfort, and optimize muscle energy utilization, meeting athletes' evolving performance needs. Methods This study involved 32 healthy male volunteers aged 18-50 years, with a BMI of 18.5-25.0 kg/m² and body weight of ≥50 kg. This study evaluated the bioavailability and safety of MuscleBlaze Creatine Monohydrate (CreAMP™) (Bright Lifecare Pvt Ltd, Gurugram, India), containing 3.0 g creatine monohydrate and 0.1 g Creabsorb™ (Indian Patent: IN202311057466), against a standard 3.0 g micronized creatine dose. In a double-blind, randomized crossover trial (CTRI/2024/08/073021), 32 healthy males (18-50 years) received both formulations under fasting conditions. The study compared two oral creatine monohydrate formulations: CreAMP™ Micronized Creatine Monohydrate (test) and Regular Micronized Creatine Monohydrate (reference) (Bright Lifecare Pvt Ltd, Gurugram, India). Blood samples were collected pre-dose and up to six hours post-dose over two periods, separated by a washout period of one week. Pharmacokinetic parameters were analyzed using Phoenix® WinNonlin® 8.5 (Certara, Radnor, PA). Results CreAMP™ has significantly higher bioavailability, absorption, and plasma retention compared to the reference formulation. With a 38.97% increase in bioavailability, an 18.10% higher C_max, a 21.37% longer half-life, 34.67% lower clearance, and a 10.13% higher mean residence time, CreAMP™ demonstrates superior pharmacokinetic properties. These findings suggest that CreAMP™ offers improved creatine uptake, sustained plasma levels, and the potential for reduced dosing frequency, making it a more effective formulation for creatine supplementation. Conclusion The study findings establish CreAMP™ as a superior creatine formulation, offering enhanced bioavailability, faster absorption, and prolonged plasma retention. These pharmacokinetic advantages indicate that CreAMP™ offers more efficient creatine uptake, improved energy availability, and optimized performance support for athletes.
