my 7 year old son had vitamin D level of 15 ng/ml. As per doctors advice I gave him supplements. After 6 months it's 73.65 ng/ml. is it worrisome?

A. You’ll have to check with your paediatrician because a clarity on this can only be advised by the doctor so just go ahead with different levels are there for vitamin D for different age groups so better to be sure about it after getting you check with the doctor
