Some of those things may help...I personally would not use colloidal silver but others may have a different opinion. Bee pollen + grape seed sound reasonable. Also, if your house is above 68 at night, no extra heat is needed. The undertank heater may dehydrate him. They are desert animals + need to cool off at night.
Don't blame yourself, all the things you gave him were things that are marketed for beardies....he is just having a reaction to something and/or possibly has an unseen hidden illness. You're a very caring owner, otherwise you wouldn't have spent so much time + money to help Fred.
