My diabetician has advised me to take one Zincovit tablet every night. My zinc level is 40, vit D is 30. Recently I had to consult a general physician for some issue and he advised to take D Rice 60,000 IU once a week. My query is, can we take zincovit everyday and at  same time take D Rice 60,000 IU once a week. As I believe zincovit has some vit D already, will it be harmful. Is there a upper limit of this vit D supplement to be taken. Please advise. Thanks in advance.
