Kalcoral-DX 600 mg + 400 IU Tablet is a dietary supplement that combines calcium and vitamin D3 to promote healthy bones and prevent deficiencies. The calcium carbonate used in Kalcoral-DX is sourced from coral, which is believed to enhance absorption due to its similarity to human bone structure. Vitamin D3 aids in the efficient absorption of calcium from the gastrointestinal tract. This combination is particularly beneficial for individuals at risk of osteoporosis, osteomalacia, and other bone-related disorders. The recommended dosage is one tablet once or twice daily, preferably with meals, or as directed by a healthcare provider.
