The USA states, I think (I may be wrong), add iodine to salt.
That doesn’t happen in the UK, and it is estimated by at least some sources I’ve checked online (a while ago)…that we are all on average 50% iodine deficient, or 50% of us are iodine deficient.
I’ll check that out later.
Anyway, after reading that I looked into iodine salt sources, especially from Indian sub continent.
I wasn’t happy with some associated contaminated risks, so I ended up buying some Sea Kelp supplements.
I don’t take them everyday, just every other day.
Hopefully this is within the rules, but these are what I got…and there are plenty of other similar products available.
Hard for me to know if they’re beneficial or not, but I don’t like the idea of so many from UK/Ireland being deficient.
