Microalbumin

Urine_kidney Unit: mg/L Urine test

Early kidney damage marker; detectable before proteinuria

Also known as: Urine Microalbumin,Albumin (urine)

Reference Ranges

Clinical Reference 0.0 – 20.0 mg/L
Optimal Range 0.0 – 10.0 mg/L

20-200 = microalbuminuria; >200 = macroalbuminuria

Related Conditions

Diabetes High
Kidney Disease High

Food & Lifestyle Recommendations

🍎 Food Reduce sodium to under 1,500mg/day — high sodium worsens albuminuria High sodium intake increases glomerular pressure and albumin excretion in CKD
🍎 Food Increase omega-3 intake: fatty fish 2-3x/week or flaxseed daily Omega-3 fatty acids reduce inflammation and albuminuria in diabetic nephropathy
🏃 Exercise Regular moderate exercise improves kidney blood flow and reduces albuminuria 150 min/week of moderate exercise reduces ACR by 10-20% in CKD trials

Evidence-Backed Supplements

When High

  • Omega 3 Tier A May Decrease

    Moderate evidence; omega-3 fatty acids reduce albuminuria in diabetic nephropathy. Meta-analyses show modest ACR reduction.

    Fish oil (EPA+DHA) 1000–2000 mg EPA+DHA/day With meals
    PMID 30019766 PMID 32114706 PMID 30480773
  • Vitamin D Tier A May Decrease

    Moderate evidence; vitamin D deficiency is associated with albuminuria. Supplementation may reduce ACR in deficient individuals.

    Vitamin D3 (cholecalciferol) 1000–2000 IU/day Morning
    PMID 19370554 PMID 24414552 PMID 24729336
  • Curcumin Tier A May Decrease AYURVEDA

    Limited evidence; curcumin has renoprotective anti-inflammatory properties. Some trials show ACR reduction in diabetic nephropathy.

    Curcumin with piperine or phytosome 500–1000 mg/day With meals
    PMID 34017975 PMID 31423805 PMID 38542668

Questions to Ask Your Doctor

  • Does my microalbuminuria indicate early kidney damage, and is it reversible? Microalbuminuria is the earliest detectable sign of diabetic nephropathy; may be reversible with tight glucose control.
  • Should I have my ACR measured regularly to track kidney health over time? Annual ACR screening is recommended for all diabetics and those with hypertension.
