Sunny D is a widely used vitamin D supplement in Pakistan, prescribed to treat and prevent vitamin D deficiency in both adults and children. It contains cholecalciferol (vitamin D3), an essential nutrient that supports bone strength, calcium absorption, muscle function, and immune health. Doctors commonly recommend Sunny D capsules when lab reports show low vitamin D levels or when deficiency symptoms start affecting daily life.
Availability & Price Information
Sunny D capsule is widely available at leading pharmacies and medical stores across Pakistan. The product is commonly dispensed against a valid prescription due to its high-dose vitamin D formulation. Availability may vary depending on location, brand distributor, and stock status.
For the most accurate and updated pricing, it is recommended to check with a trusted pharmacy or verified diagnostic and healthcare platforms before purchase. This ensures you receive an original product with proper storage and handling.
Composition / Ingredients
Sunny D contains a single active ingredient:
Cholecalciferol (Vitamin D3)
Vitamin D3 is the naturally occurring form of vitamin D that the human body produces when skin is exposed to sunlight. Compared to other forms, vitamin D3 is more effective at raising and maintaining adequate vitamin D levels in the blood.
Key benefits of cholecalciferol include:
-
Improves calcium and phosphate absorption from food
-
Supports healthy bones and teeth
-
Helps prevent rickets in children and osteomalacia in adults
-
Contributes to proper muscle function
-
Supports immune system balance
Because Sunny D is a high-dose vitamin D supplement, it is often prescribed as a capsule or stat dose, rather than a daily low-strength tablet.
How Sunny D Works
Sunny D works by restoring vitamin D levels in the body, which are essential for calcium and phosphate regulation. After ingestion, cholecalciferol is absorbed from the intestine and then converted in two steps:
-
Liver conversion: Vitamin D3 is converted into 25-hydroxyvitamin D
-
Kidney conversion: It is further converted into 1,25-dihydroxyvitamin D, the active form
This active form helps:
-
Increase calcium absorption from the gut
-
Maintain normal blood calcium and phosphate levels
-
Support bone mineralization
-
Works alongside parathyroid hormone and calcitonin to keep bones strong
Without adequate vitamin D, calcium absorption drops significantly, even if dietary calcium intake is sufficient. This is why Sunny D capsule therapy is commonly recommended in deficiency states.
Uses / Indications of Sunny D
Sunny D capsule uses are well-established in clinical practice. Doctors prescribe it for the following conditions:
-
Vitamin D deficiency confirmed by blood tests
-
Bone disorders such as rickets, osteomalacia, and osteoporosis
-
Muscle weakness and bone pain related to low vitamin D
-
Prevention of fractures in high-risk patients
-
Malabsorption syndromes where vitamin D uptake is reduced
-

-
Patients using long-term steroids or anticonvulsants
