Does anyone have a vitamin allergy?

I was curious if my son has a vitamin D allergy :

Oral vitamin D supplementation has been introduced into modern medicine to

prevent rickets without the knowledge that this may have profound immunological

consequences. The main vitamin D metabolite calcitriol suppresses dendritic cell

maturation and consecutive Th(1) cell development, which has independently

described as a key mechanism of allergy development. Animal studies and

epidemiological surveys now provide a first link of early vitamin D

supplementation and later allergy where several vitamin D regulated genes seem

to be involved. A randomized clinical trial of vitamin D supplementation could

be a further step to follow up the vitamin hypothesis.
