Pls suggest a good vitamin supplement for my 8 yr girl child.?

Plenty available. It is a mistake to believe that taking a pill "lets us off thehook". Vitamin supplements do not work well unless the diet is as pristine as you can afford. Most diets today have too many empty calories and, as I have said many times in these posts, sugar in all its forms is definitely injurious to health.See my blog "oxygen, the spark of life" that you can google.
