Drug Class: High-Strength Vitamin D3 Supplement (Cholecalciferol) | Form: Chewable Tablet | Status: OTC Supplement — DRAP Registered | Pack: As per pack size | Manufacturer: Bin Sultan Pharma
What is D3-Fact Chewable 4000 IU?
D3-Fact is a high-strength chewable Vitamin D3 supplement by Bin Sultan Pharma providing 4000 IU of Cholecalciferol per tablet. It is designed for adults with significant Vitamin D deficiency requiring more than standard low-dose supplements can provide. The chewable format makes it convenient and easy to take without water. D3-Fact supports calcium and phosphorus absorption for bone strength, immune function, and recovery after injury or surgery — and helps address the fatigue commonly associated with Vitamin D deficiency.
What is D3-Fact Used For?
- Treatment of significant Vitamin D deficiency (وٹامن ڈی کی کمی)
- Supporting bone strength and density (ہڈیوں کی مضبوطی)
- Supporting healthy teeth development and maintenance (دانتوں کی صحت)
- Strengthening immune system function (قوت مدافعت)
- Supporting recovery after bone fractures, injury, or surgery (ہڈی کے ٹوٹنے کے بعد صحتیابی)
- Reducing fatigue and muscle weakness linked to Vitamin D deficiency (تھکاوٹ اور کمزوری)
- Supporting calcium and phosphorus absorption in the gut
- Seasonal deficiency correction in individuals with limited sun exposure
How Does D3-Fact Work?
Cholecalciferol (Vitamin D3) is converted in the liver and kidneys into its active hormonal form — calcitriol — which regulates calcium and phosphorus absorption in the intestine. This is essential for maintaining strong bones, healthy teeth, and normal muscle function. Vitamin D3 also plays a critical role in immune system regulation, reducing inflammation, and supporting mood and energy levels. At 4000 IU, D3-Fact provides a therapeutic correction dose for adults with confirmed deficiency — significantly more effective than standard 400–1000 IU maintenance supplements for rapidly restoring depleted Vitamin D levels.
Dosage and Administration
| Indication | Dose | Frequency |
|---|---|---|
| Significant Vitamin D deficiency | 1–2 tablets | Once daily as prescribed |
| Bone recovery post-fracture or surgery | 1–2 tablets | Once daily as directed by doctor |
| Immune & general D3 support | 1 tablet | Once daily |
⚠️ Chew tablet completely before swallowing. Take with or after a meal containing fat — Vitamin D3 is fat-soluble and absorbs best with dietary fat. Do not exceed 2 tablets daily without medical supervision. At 4000 IU, regular blood level monitoring is advisable with prolonged use. Always follow your doctor's instructions.
Active Ingredients
| Ingredient | Strength per Tablet |
|---|---|

Who Should NOT Take D3-Fact?
- Patients with hypercalcaemia — already high blood calcium levels (خون میں کیلشیم کی زیادتی)
- Patients with hypervitaminosis D — already excess Vitamin D levels
- Patients with kidney stones — Vitamin D increases calcium absorption and may worsen risk (گردے کی پتھری)
- Patients with sarcoidosis or granulomatous diseases — increased sensitivity to Vitamin D
- Patients with severe kidney disease — without specialist supervision
- Children — 4000 IU is an adult dose; never give to children without paediatric medical guidance
- Pregnant or breastfeeding women — only under medical supervision at this dose
Side Effects
Common (usually from excessive or prolonged dosing):
- Mild nausea or stomach discomfort
- Mild constipation or dry mouth
- Headache with very high intake
Serious (Stop and seek medical attention immediately if):
- Signs of Vitamin D toxicity or hypercalcaemia — excessive thirst, frequent urination, confusion, muscle weakness, irregular heartbeat (یہ طبی ہنگامی صورتحال ہے)
- Kidney pain or significantly reduced urine output
- Severe nausea, vomiting, or loss of appetite with prolonged high-dose use
Drug Interactions
| Medicine / Substance | Possible Interaction |
|---|---|
| Thiazide diuretics (e.g., Hydrochlorothiazide) | Increases calcium reabsorption — combined with high-dose D3 raises hypercalcaemia risk |
| Digoxin (heart medicine) | Hypercalcaemia from excess Vitamin D increases Digoxin toxicity risk — monitor closely |
| Calcium supplements | Combined use increases risk of excessively high blood calcium — monitor levels |
| Cholestyramine / Orlistat | Reduce Vitamin D absorption — separate doses and monitor levels |
| Anticonvulsants (e.g., Phenytoin, Carbamazepine) | Accelerate Vitamin D breakdown — higher doses may be needed under supervision |
| Magnesium supplements | Vitamin D and Magnesium are interdependent — generally beneficial combination |

Frequently Asked Questions (FAQs)
Q: How is D3-Fact 4000 IU different from standard Vitamin D supplements?
Standard Vitamin D supplements typically provide 400–1000 IU for daily maintenance. D3-Fact at 4000 IU is a therapeutic correction dose designed to rapidly restore significantly depleted Vitamin D levels — it is not a routine maintenance supplement and should be used under medical guidance.
Q: Do I need a blood test before taking D3-Fact 4000 IU?
A blood test to confirm Vitamin D deficiency is strongly recommended before starting high-dose supplementation. This allows your doctor to prescribe the correct dose and duration — and schedule follow-up testing to confirm levels have normalised.
Q: How long should D3-Fact 4000 IU be taken?
Duration depends on the severity of deficiency and your doctor's assessment. Once Vitamin D levels are corrected — typically within 8 to 12 weeks — your doctor will likely reduce the dose to a standard maintenance level to avoid toxicity.
Q: Can D3-Fact be taken alongside a calcium supplement?
Yes, Vitamin D3 and Calcium work together for bone health. However, monitor total daily calcium intake from all sources to avoid hypercalcaemia. Inform your doctor about all supplements you are taking.
