Perlu dicatat bahwa asupan vitamin D yang berlebih, baik karena asupan vitamin D yang berkepanjangan atau dosis tambahan yang berlebihan, dapat menyebabkan hiperkalsemia dan/atau hiperkalsiuria. Studi kasus menunjukkan bahwa suplemen vitamin D 50.000-300.000 IU/hari dapat menyebabkan hiperkalsemia dalam beberapa minggu. Â
