Cholecalciferol 60,000 IU supports bone, muscle, and immune health by raising vitamin D levels and enhancing calcium and phosphorus absorption. It helps improve bone mineral density, reduces risk of rickets and osteomalacia, and is often used in osteoporosis care alongside lifestyle measures. Beneficial for people with limited sun exposure, darker skin, older age, or malabsorption conditions, it can also ease nonspecific musculoskeletal aches linked to deficiency. Consistency with food improves uptake, and pairing with a nutrient-rich diet and sensible sunlight exposure strengthens outcomes. It’s widely available as softgels, tablets, or sachets and is commonly recommended under clinician guidance.
