•Potential interactions with thiazide diuretics, cardiac glycosides, and cholestyramine may alter vitamin D metabolism or increase calcium levels in this formulation.
•Safe for healthy adults; contraindicated in hyperparathyroidism, kidney disease, or hypercalcemia due to risk of exacerbating calcium imbalances.
•Likely safe in pregnancy up to 4,000 IU daily, but higher doses like 5,000 IU should be used only under medical supervision to prevent potential fetal risks.
