Vitamin D3, also known as cholecalciferol, is an active form of vitamin D. Vitamin D is a fat-soluble vitamin which possesses hormone-like activity and regulates calcium and phosphate metabolism. In addition, vitamin D also affects neuromuscular function, inflammation, and influences the action of many genes that regulate cell proliferation and differentiation and programmed cell death.
In adults, the production of vitamin D by skin cells upon sunlight exposure is minimal. Therefore, most of the required vitamin D in adults comes with food.
Vitamin D deficiency in adults can cause osteopenia/osteoporosis, joint pain and abnormal deposition of calcium salts in the joints (pseudogout).
Potential side effects:
- Joint pain
- Muscle pain
- Abdominal pain
Potential drug interactions:
- Aluminum based antacids
- Calcipotriene (Dovonex)
- Calcium channel blockers
- Thiazide diuretics (water pills)
- Cimetidine (Tagamet)
- Low molecular weight heparins
- Strontium Citrate
- High levels of calcium in the blood
- Hardening of the arteries (atherosclerosis)
- Over-active parathyroid gland (hyperparathyroidism)

The recommended dose of vitamin D3 varies between 1000 to 10000 units a day and ideally should be adjusted to the blood level of vitamin D.
