eGFR

eGFR estimates how well your kidneys are filtering waste from your blood. It’s calculated using your creatinine level, age, sex, and sometimes race. Lower values can indicate reduced kidney function or chronic stress on the system—often from dehydration, high blood pressure, or overtraining. It’s a key metric for overall healthspan, especially in high-protein or high-supplement protocols.
