That's a good SSKI solution. I'm no expert on these matters, and I don't know of a way to test whether it's still good, but I'd probably take it :) 'Course, I know how I feel on it, and I'd notice if there was a change.
Some people do great on just Lugol's. Women especially need Lugol's or Iodoral to get the iodine. Men? Maybe a small amount of Lugol's and the rest SSKI. My husband just takes SSKI. He originally took Iodoral, then a combo, then eventually fell into just SSKI. It might depend on how high you dose. After 100 mg or so, Lugol's or Iodoral can get rough, and SSKI fills the gap beautifully.
