Iodine-Supplement

Iodine is necessary in the diet for growth and to regulate metabolism. Only a small amount (as little as 1 mg daily) is needed.

Sufficient iodine is included in most commercial feeds.

If you still think your horse lacks iodine, a little iodized salt or mineral salt (such as is afforded by an equine salt or mineral block) can supply it. Kelp products also contain iodine. But the danger is usually of supplying too much iodine rather than too little. It's best to check with your veterinarian before adding iodine to a horse's ration.
