DS was on adeks drops, then aquaadeks drops -- we were having difficulties getting those for awhile, so I started using a bottle of Source CF bubblegum flavored chewables. He likes those better, so switched him to those. His doctor has him take two a day, plus he gets 1 mg of vitamin K per week, a 400 iu of Vitamin E daily and a 10,000 iu of Vitamin A daily
