Creatine: A Hack To Get Jacked?

What It Covers

Science Vs examines creatine supplementation claims for muscle building and cognitive enhancement, reviewing research on effectiveness, response rates, safety profiles, and optimal dosing strategies based on studies involving muscle biopsies and sleep deprivation experiments.

Key Questions Answered

• •Muscle growth mechanism: Creatine increases ATP recycling speed during workouts, enabling two to three extra reps per set. Studies show muscle thickness increases by 0.1 centimeters, though one in four people show no response to supplementation.
• •Olympic perspective: World Anti-Doping Agency does not ban creatine because it fails to meet criteria for being sufficiently performance enhancing. US Anti-Doping Agency states effects are small and not guaranteed, indicating limited competitive advantage.
• •Cognitive benefits: Sleep-deprived subjects showed significantly faster processing speeds and improved memory on creatine in MRI-monitored studies. However, a larger 123-person study found no statistically significant cognitive improvements in healthy, well-rested individuals during six weeks of supplementation.
• •Dosing protocol: Skip the loading phase of 20-25 grams daily. Muscles saturate within four days at standard 3-5 gram doses. Higher amounts get urinated out without additional benefit, making loading phases unnecessary and wasteful.
