Colecalciferol/calcium carbonate

Vitamin D deficiency is widely prevalent in India. Serum 25(OH)D levels are <20 ng /ml in up to 90% of them. Recently, in a randomized control trial, investigators have shown that dual cholecalciferol and calcium supplementation lead to significant improvement in hand grip strength and distance covered during six minutes walk test. Present study is being taken to further understand the functional significance of 25(OH)D in terms of its effect on Skeletal muscle strength including surface electromyography (EMG) in a larger cohort involving approximately 200 subjects. The impact of calcium and vitamin D supplementation would be assessed by supplementing them alone and in combination. Besides, the investigators would also assess impact of above supplementation on Th1/Th2 cytokines expression in the peripheral mononuclear cells.

The purpose of this trial is to assess the effect of vitamin D supplementation on recurrence in resected stage II melanoma patients.
