[YEA] Lugol's iodine caused my heart to palpitate (and not in a good way; the bad way). So I thought no more Lugol's. I felt bad because I read the health benefits on this site and others and I could not take even one drop. Then while researching fatty acid metabolism I found that you use a lot of vitamin B-1, B-6 and B-12. All the of these B's have heart palpitations as a sign of their deficiencies. So I took all three. Now I can take Lugol's. Yeah!
Also selenium and zinc deficiencies can cause heart palpitations. So if you can't take iodine because of the heart quivers you might have a deficiency you need to correct first.
