I’ll explain what a 25 ng/mL 25‑hydroxyvitamin D result likely means for someone with Chronic Kidney Disease (CKD) and practical supplement options.

⚕️ What this likely is

• Your 25‑hydroxyvitamin D (25(OH)D) of 25 ng/mL is consistent with vitamin D deficiency (you noted a target >75 ng/mL).
• In Chronic Kidney Disease (CKD), production of active vitamin D can be impaired, so deficiency is common and may need supervised repletion.

💊 Supplement options & typical dosing

• Maintenance: cholecalciferol (Vitamin D3) 1,000–2,000 International Units (IU) daily is commonly used for maintenance; Gen‑D3 1K (1,000 IU) is an India-available product option for maintenance.
• Repletion (common regimen): under doctor supervision, many clinicians use 60,000 IU weekly for 8–12 weeks (or 50,000 IU weekly) then switch to maintenance — this more reliably raises 25(OH)D from ~25 to target ranges.
• Important CKD caveat: if CKD is advanced (later stages) you may require active vitamin D (calcitriol) or analogues rather than high-dose cholecalciferol.

🩺 Practical next steps

• Discuss dosing with your nephrologist before starting or increasing supplements.
• If approved, consider repletion (weekly high-dose) followed by maintenance, with lab monitoring.
• Monitor serum calcium, phosphate, parathyroid hormone (PTH) and repeat 25(OH)D after ~8–12 weeks.

⚠️ Warning signs (stop and seek care)

• Symptoms of high calcium: nausea, vomiting, confusion, muscle weakness.
• New or worsening kidney pain or decreased urine output.
• Lab-confirmed hypercalcemia.
