Logi-Cal-500 Tablet is a combination supplement containing Calcium 50 mg and Vitamin D3 400 IU, formulated to support bone health and maintain optimal calcium levels in the body. Calcium is a vital mineral essential for the development and maintenance of strong bones and teeth, playing a critical role in muscle function, nerve transmission, and vascular contraction. Vitamin D3 (cholecalciferol) enhances calcium absorption from the gastrointestinal tract, ensuring adequate serum calcium concentrations necessary for normal bone mineralization. This combination is particularly beneficial in the prevention and management of calcium deficiency states, including osteoporosis, osteomalacia, and rickets. Logi-Cal-500 is indicated for individuals at risk of or experiencing calcium insufficiency due to inadequate dietary intake, malabsorption syndromes, or increased physiological demands such as pregnancy, lactation, and aging. The tablet should be taken orally, preferably with meals to improve absorption. Caution is advised in patients with hypercalcemia, hypervitaminosis D, or renal impairment. Regular monitoring of serum calcium and vitamin D levels is recommended during prolonged therapy. Logi-Cal-500 offers an effective and convenient approach to maintaining skeletal health and preventing metabolic bone disorders when used as part of a balanced diet and lifestyle.
