Creatine Research Timeline
30+ years of landmark discoveries — from muscle loading to brain health
Creatine loading protocol discovered
First demonstration that oral creatine supplementation increases muscle creatine stores by ~20%, establishing the loading protocol used worldwide today.
Loading vs maintenance dosing defined
Established that 20g/day for 5-7 days saturates muscles, followed by 3-5g/day for maintenance. This protocol remains the gold standard.
Brain cognitive benefits proven
First RCT showing creatine improves working memory and processing speed. Particularly significant for vegetarians with lower baseline creatine.
Neuroprotection in brain injury
Animal study showing creatine reduced brain damage by up to 50% in traumatic brain injury, sparking neuroprotection research.
Sleep deprivation mitigation
Creatine supplementation offset cognitive decline from sleep deprivation, maintaining mental performance under fatigue.
Full creatine kinase system mapped
Comprehensive review mapping how the creatine kinase system operates in muscle, brain, and other tissues, revealing pleiotropic effects.
ISSN safety position stand
International Society of Sports Nutrition confirms creatine monohydrate is the most studied and safest sport supplement available, with no adverse effects in healthy populations.
Systematic review: cognitive benefits supported
Systematic review of 6 RCTs finds evidence that creatine improves short-term memory and reasoning, especially under stress or in older adults. Results for other cognitive domains were mixed.
Brain health review: creatine neuroprotection
Comprehensive review of creatine and brain health — consolidates evidence for cognitive enhancement, neuroprotection, and potential benefits for neurological conditions.
Three Decades of Creatine Research
Creatine is one of the most extensively studied sports supplements in history, with over 500 peer-reviewed publications. The timeline above traces the major milestones — from Roger Harris's landmark 1992 paper demonstrating that oral creatine supplementation increases muscle creatine stores, through the explosion of performance research in the late 1990s, to modern investigations into cognitive benefits and clinical applications.
