Iodine toxicity

["Barbara B. Peck" <bpeck@together.net>]

2 to 5 milligrams (mg) per day is the horses daily requirement for

iodine. 

 There's about 2.5 mg iodine in 36 grams of iodized salt, which is about 2 tablespoons of salt ( 2 tablespoons of salt is a little over an ounce of salt)

 

The toxic level, from iodized salt, is about 40 mg/day ( fed daily for several months.)

 

From kelp, the toxic level is 350 mg/day  (fed  daily over several months.)
