Peak Performance Creapure Creatine Monohydrate Capsules

Clinical trials typically use 3-5 g daily (creatine monohydrate). Peak Performance Creapure Creatine Monohydrate Capsules delivers 5g creatine monohydrate per serving (capsule form), which we classify as Therapeutic relative to that range.

Creatine monohydrate is one of the most extensively studied supplements in history, with over 700 clinical trials confirming its safety for long-term daily use. Creapure certification guarantees 99.99% purity from AlzChem in Germany, free from contaminants like creatinine and dicyandiamide. Daily use at 3-5g is considered safe for healthy adults.

Creatine has no well-documented clinically significant drug interactions. However, because creatine is processed by the kidneys, individuals taking nephrotoxic medications or those with pre-existing kidney conditions should consult their doctor before supplementing. Creatine does not harm healthy kidneys at recommended doses.

Creatine monohydrate is very well tolerated. The most common effect is mild water retention during the first 1-2 weeks as muscles become saturated. Occasional reports of bloating or stomach discomfort can be minimized by splitting the dose across the day or taking with food. The capsule form eliminates taste-related issues.

The International Society of Sports Nutrition considers creatine safe for adolescents engaged in supervised training programs. However, younger athletes should consult a healthcare provider before starting creatine. The standard 3-5g daily dose used in adult studies is typically appropriate for older teens.

No. Multiple long-term studies have shown that creatine monohydrate does not harm kidney function in healthy individuals. This myth persists because creatine increases creatinine levels in blood tests (a kidney marker), but this is a benign byproduct of creatine metabolism, not a sign of kidney damage. Those with pre-existing kidney disease should consult their doctor.

Take capsules providing 5g of creatine monohydrate per day, which is the clinically established maintenance dose. No loading phase is required, though taking 20g daily for 5-7 days can saturate muscles faster. Check the label for how many capsules equal one 5g serving.
