Reply To: My vitamin D total (250H D2 and 250H D3) test report says, its too low ( 4.7 ng /mL ). My doctor prescribed me 500IU vitamin D3 pills and 0.25 mcg Calcium pills and asked me to take each one every day. For my level I feel like taking one pill is not enough. Can someone advise me? I have pain in my hands. Its feel like my blood vains are about to burst.
