hi All, I was giving the vitamin D3 800IU/ML 0.5ml daily night. Now I changed to other state and I am getting the same vitamin d3 800IU/ML instead they provided vitamin D3 400IU/ML in medical. Now I am confused how much ml I need to give whether to give 0.5 ml which I used to give with 800UI/ML drops or 1ml do I need to consult the pead and need to act as per their suggestion.???
