i have found digestive enzymes on occasion to be helpful. hydrochloric acid production decreases significantly with age as well and can be helped with organic apple cider vinegar. dr hays book on eating is very helpful. mixing food properly and the orange juice fast is in there.
i think the SSKI 2% is a perfect upgrade for your supplement. it will allow you to get less Iodine thats magnetized somewhat and more KI which acts as an anti-oxidant and does not produce the detox of the elemental.
as for dosage, no one knows better than you. my dad takes 4 drops of SSKI twice a day. thats almost 200mg of pure Iodine every day. he cant believe he feels as good as he does at his age(his own words).
one of the places some get stuck at is all the trace metals that cobalt moves around can be gone. this taxes the body tremendously. the only cobalt we can use is that in vitamin B12. if youre low enough on it you cant even absorb that with supplements. an injection is in order. if benefit is felt from the injection(1mg of B12) then one every day until that benefit can no longer be felt after the shot. then you are up and running. no other form can do it. the injection lets you know for sure.
i cant tell ya how many people have been having a hard time on 50mg and when they doubled that it all got easier.
