Creatine Supplement Guide
Evidence-based information on Creatine benefits, dosage, safety, and food sources — sourced from NIH, FDA, and PubMed.
Our assessment
The evidence shows that creatine is one of the most researched and effective supplements for supporting muscle function and energy production. Our assessment: it is a reliable option for you if you are looking to improve physical performance or support muscle health, particularly during high-intensity exercise. The data confirms its role in enhancing cellular energy systems NIH ODS ↗.
How it works
Think of creatine as a cellular energy booster. It works by supporting mitochondrial efficiency and biogenesis, which helps your cells produce more ATP (your body's primary energy currency). Additionally, it stimulates muscle protein synthesis through the mTOR pathway, helping you build and maintain lean muscle mass NIH ODS ↗.
Safety profile
Data not available on specific adverse event reports from the FDA data provided. No side effects or report counts are listed in the supplied data. The NIH ODS notes its mechanism of action but does not provide safety or side effect information in the data given NIH ODS ↗.
Our recommendation
For most people, a standard dose of 3 to 5 grams daily is well-supported by the research. You can take it consistently to maintain elevated muscle creatine stores. As always, consult your healthcare provider before starting any new supplement, especially if you have kidney concerns. Choose a pure creatine monohydrate product for the best evidence-based results NIH ODS ↗.
