You might want to consider adding extra Algin to the Heavy Metal Detox...even though there's some Algin already in it. (I always recommend Algin with ANY chelator to make sure that mercury doesn't get reabsorbed.)

Try to make sure the child drinks plenty of water (which is often difficult with kids). This will help enhance bowel elimination. If you start seeing a decline in the child's behavior, mood, energy levels, etc., then definitely add extra Algin.
