                                According to the NIH Office of Dietary Supplements, it is highly unlikely for a child to get too much magnesium from food alone, but excess intake from supplements and medications poses a real risk. This is a crucial distinction for parents to understand, as the question of 'can a child have too much magnesium' has a different answer depending on the source.
