Sterol-D Stat 200,000IU Capsules — Medical-Grade Vitamin D3 Loading Dose

For use under healthcare professional supervision. This is a high-dose loading formulation — not a daily supplement.

Sterol-D Stat 200,000IU Capsules contain Cholecalciferol (Vitamin D3) at an ultra-high loading dose of 200,000 International Units per capsule. This formulation is used for rapid correction of severe Vitamin D deficiency using stoss therapy — a single or periodic bolus dose prescribed when standard daily supplementation is too slow or impractical.

Vitamin D deficiency is highly prevalent in Pakistan due to limited sun exposure, dietary patterns, and high rates of osteomalacia. A 200,000IU loading dose rapidly replenishes depleted stores and restores serum 25-hydroxyvitamin D [25(OH)D] to adequate levels. Maintenance therapy at lower doses (typically 400–1000IU daily) is usually continued after the loading dose under medical guidance.

Key Benefits

• Rapid deficiency correction — restores 25(OH)D levels quickly in severely deficient patients
• Bone mineralisation — Vitamin D3 enhances intestinal calcium and phosphate absorption, critical for bone density
• Muscle function — Vitamin D deficiency is associated with proximal muscle weakness; correction improves strength
• Immune modulation — Vitamin D plays a role in innate and adaptive immune function
• Mood and energy — low Vitamin D is associated with fatigue and low mood; correction may improve these symptoms

Directions for Use

This is a loading dose — take only as prescribed by your physician. Typical stoss regimens involve a single 200,000IU dose or periodic dosing (e.g., monthly or quarterly). Do not self-administer at this dose without medical oversight. Swallow whole with a full glass of water. Calcium levels should be monitored during Vitamin D therapy, particularly in patients on thiazide diuretics or with granulomatous disease.

FAQs

• Q: Why is 200,000IU so much higher than standard doses?
  A: Standard daily doses (400–1000IU) are for maintenance. A 200,000IU loading dose is prescribed by doctors to rapidly correct a proven severe deficiency — it is equivalent to taking daily doses for many months in a single dose.
• Q: Can I take this without a prescription?
  A: While classified as a supplement in Pakistan, use of a 200,000IU dose should only occur under medical supervision. Excessive Vitamin D can cause hypercalcaemia. Always have your 25(OH)D level tested first.
• Q: How long does the effect of one loading dose last?
  A: A single 200,000IU dose typically raises serum 25(OH)D for 2–3 months. Your doctor will determine whether maintenance doses are required.
• Q: Who is most at risk for Vitamin D deficiency in Pakistan?
  A: Women in full purdah, elderly individuals with limited mobility, individuals with dark skin, and those with malabsorption conditions are at highest risk.
