What is D-Sun Capsules?
D-Sun Capsule is a high-dose Vitamin D3 supplement containing Cholecalciferol 50,000 IU per capsule, used to treat and prevent Vitamin D deficiency (وٹامن ڈی کی کمی) in adults. This high-potency formulation is prescribed when standard low-dose supplements are insufficient to correct severely low Vitamin D levels. Cholecalciferol is the most bioavailable and effective form of Vitamin D, and once taken, it is converted in the liver and kidneys into its active form, which regulates calcium absorption, supports bone mineralisation, strengthens the immune system, and maintains muscle function. It is commonly prescribed for patients with limited sun exposure, fat malabsorption disorders, or established Vitamin D deficiency confirmed by blood tests.
What is D-Sun Used For?
Vitamin D Deficiency Treatment: Corrects severely low Vitamin D levels in adults with confirmed deficiency, particularly those with limited sun exposure, darker skin, or fat malabsorption conditions. Bone Health and Osteoporosis: Supports calcium absorption and bone mineralisation to manage and prevent osteoporosis, osteomalacia (softening of bones), and rickets. Fracture Risk Reduction: Strengthens bone density and muscle function in elderly patients to reduce the risk of falls and fragility fractures. Immune System Support: Maintains healthy immune function and overall wellbeing in patients with low Vitamin D levels.
How Does D-Sun Work?
Cholecalciferol (Vitamin D3) is absorbed from the gut and transported to the liver, where it is converted to Calcidiol. The kidneys then convert Calcidiol into Calcitriol, the biologically active form of Vitamin D. Calcitriol regulates calcium and phosphate absorption from the intestine, supports calcium deposition into bone tissue, and maintains the blood calcium levels needed for normal muscle contraction and nerve function. High-dose D-Sun capsules rapidly replenish depleted Vitamin D stores, restoring these essential physiological functions.
Dosage and Administration
| Situation | Dose | Frequency |

Who Should NOT Use D-Sun Capsules?
Do not use if you have hypercalcaemia (high blood calcium), hypervitaminosis D (Vitamin D toxicity), kidney stones, or a known allergy to any ingredient. Tell your doctor if you have kidney disease, sarcoidosis, or are taking thiazide diuretics or digoxin, as these can interact with high-dose Vitamin D. Inform your doctor if you are pregnant or breastfeeding.
Side Effects
Common: Nausea, constipation, headache, and dry mouth are uncommon at prescribed doses but may occur with excessive intake. Serious (seek immediate help): Signs of Vitamin D toxicity including excessive thirst, frequent urination, confusion, weakness, and kidney pain. Signs of hypercalcaemia including nausea, vomiting, and irregular heartbeat.
Storage
Store below 25°C in a dry place away from direct sunlight and moisture. Keep out of reach of children (بچوں کی پہنچ سے دور رکھیں). Do not use after the expiry date. Store in original packaging.
Frequently Asked Questions
How do I know if I need D-Sun 50,000 IU capsules?
D-Sun 50,000 IU is prescribed only for confirmed Vitamin D deficiency diagnosed through a blood test measuring 25-hydroxyvitamin D levels. Do not take high-dose Vitamin D supplements without a confirmed diagnosis and prescription, as excessive Vitamin D can cause toxicity.
How long does it take for D-Sun capsules to correct Vitamin D deficiency?
Most patients see significant improvement in blood Vitamin D levels within 8 to 12 weeks of the prescribed loading dose regimen. Your doctor will recheck your levels after the course and prescribe an appropriate maintenance dose to keep your Vitamin D within the normal range.
