You've probably heard that creatine is bad for your kidneys. Or that it's just for bodybuilders. Or that it causes hair loss.
Let me give you the actual evidence.
Creatine monohydrate is the most studied ergogenic supplement in sports science history. 70+ years of research and over 500 published peer-reviewed studies. The ISSN Position Stand concluded it is the most effective nutritional supplement available for high-intensity exercise performance and lean body mass.
The kidney concern stems from a misunderstanding: creatine metabolizes to creatinine in the blood, a standard marker used to assess kidney function. When you supplement, your creatinine rises. That is normal metabolism, not kidney damage. Multiple controlled trials in healthy individuals show no adverse renal effects.
The "just for bodybuilders" assumption? Contradicted by the data. 47,000 people search "is creatine for women?" every month. Women have lower baseline creatine stores than men, and multiple studies show they respond equally well or better. Older adults fighting muscle loss and patients recovering from orthopedic surgery are among the strongest candidates.
For orthopedic recovery specifically: after surgery, disuse atrophy starts quickly. Creatine supplementation alongside physical therapy helps preserve lean muscle mass and support neuromuscular function during rehabilitation.
One angle worth knowing: the brain runs on the same phosphocreatine energy system as muscle. A 2021 review in Nutrients (Roschel et al.) found evidence for creatine's role in brain energy metabolism and cognitive function, including reduced mental fatigue and improved processing speed. This is particularly relevant for athletes managing high training loads, older adults focused on brain health, and anyone dealing with the cognitive demands of competition and recovery.
The dose is straightforward: 3-5 grams of creatine monohydrate per day. No loading phase. No complicated timing. Just consistency.
