➤ *KEY INSIGHTS FROM THIS VIDEO:*
• Creatinine is simply muscle waste that healthy kidneys filter out—rising levels mean declining kidney function
• Normal ranges: Men 0.6-1.2 mg/dL, Women 0.5-1.1 mg/dL—but individual trends matter more than single numbers
• Creatine supplements can temporarily elevate creatinine without harming kidneys—important to disclose to your doctor
• Foamy urine may indicate protein spillage even when creatinine is still normal—catch kidney disease at its earliest stage

_______

➤ *SCIENTIFIC REFERENCES:*
• Creatinine as GFR Marker: Serum creatinine reflects kidney filtration capacity, with levels inversely related to glomerular function
• Gender Differences in Creatinine: Men typically have higher baseline levels due to greater muscle mass and creatinine production
• Creatine Supplementation Effects: Oral creatine converts to creatinine, temporarily elevating blood levels without kidney damage—important for test interpretation
