Creatine monohydrate is the most studied supplement in sports nutrition. Learn how it works, proven benefits, correct dosage, safety facts, and who benefits most.
Frequently Asked Questions
What does creatine monohydrate do to your body?
Creatine monohydrate increases phosphocreatine stores in your muscles by 20–40%, giving your cells more raw material to regenerate ATP during intense effort. This translates to greater strength, more explosive power, faster recovery, and — with consistent resistance training — more muscle mass over time.
Is it OK to take creatine monohydrate every day?
Yes. Daily use is not only safe but recommended. Continuous supplementation maintains elevated muscle creatine stores. No evidence supports the need to cycle off creatine; stopping simply lowers stores back to baseline within 4–6 weeks.
What are the side effects of creatine monohydrate?
Most people tolerate creatine very well. The most common side effect is an initial 1–2 lb increase in body weight from intracellular water retention — not fat. Some people experience mild GI discomfort during the loading phase; splitting doses and taking creatine with food resolves this in most cases.
Does creatine monohydrate damage your kidneys?
No. Decades of research and multiple meta-analyses confirm that creatine supplementation at recommended doses does not harm kidney function in healthy individuals. A temporary rise in serum creatinine on blood tests is a metabolic byproduct of creatine breakdown — not a sign of kidney damage.
How long does creatine monohydrate take to work?
With a loading protocol (20 g/day for 5–7 days), you can saturate muscle stores in about one week and notice strength improvements shortly after. Without loading, taking 3–5 g/day reaches full saturation in approximately 3–4 weeks. Most people notice meaningful performance improvements within two to four weeks.
