Creatine vs. Creatinine: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 25, 2023
Creatine is a natural compound aiding muscle energy, while creatinine is a waste product from creatine breakdown.

Key Differences

Creatine is an amino acid derivative found in muscle cells, enhancing energy production, whereas creatinine is a chemical waste molecule generated from muscle metabolism.
