Feeding salt with iodine?

I feed salt with iodine, but I had a feed analysis done which said my boy needed the iodine.
Fed in excessive amounts ( I don't know how excessive they would need to be ) Iodine would cause thyroid problems...
I'm sure the amount youd feed, to use the bag wouldn't do any harm, or you could use it on your food and buy your horse one without if you are worried.

In the US, there is 1.72mg of iodine in 1oz. of salt. Up to 2oz. of salt should be fed to a 1000lb. horse at work for sweat losses, providing 3.4mg. of iodine/day. NRC requirements at 150% is 5.3mg.of iodine/day. 5.3 less 1.72 = 3.58mg still needs to be supplemented.
The iodine in salt content may differ where you are and you will need to find out the correct numbers, but this is the way you should go about it.
Kelp has good iodine, but may be too good. The source of that kelp should also be checked. When feeding such products, use this standard to deliver only the amount of iodine needed vs. the feeding directions. You may even find that the kelp replaces the need for iodine in salt, but don't let it. The need for the electrolytes in salt is still needed. Horses can be dehydrated and their body tricking them into thinking they aren't, so the benefit of salt driving thirst will still be important.
Success is not guessing or supplementing over or under, its about balance....dead on.
Hope this helps.....
