Hello Sara,
Every young child got a positive result.I would say 4 or 5.However,since children
can be more sensitive,we proceed slowly.In the beginning,use one 400 IU capsule in 1.5 tablespoons of distilled water.If that gives a positive result,stay at one capsule.If no positive or negative results,use 2 capsules the next day.Since you already found the diet effective,there is no need to tell you it's importance.
Then give an updated posting after the 1 or 2 capsule level.sheldon
