Short answer: YES. The company says: "Real Salt does contain naturally-occurring iodine, but not enough to satisfy the recommended daily allowance of 150 micrograms. Real Salt doesn't provide the recommended daily allowance of protein, either. Or fat. Because nature intended salt to provide our bodies with sodium chloride and trace minerals!
So, instead of using chemically-processed, unhealthy salt in order to get iodine, we like to stick with Real Salt and get naturally occurring iodine from other delicious sources like kelp, yogurt, eggs, strawberries, and mozzarella cheese."

From the bag: "Long ago in what is now Central Utah, Native Americans found a mineral-rich salt deposit from an ancient sea when they saw deer eating the soil. In 1959,Milo and Lamar Bosshardt were struggling to keep their family afloat when they discovered that this salt deposit extended beneath their land. They began selling the salt to local farmers for their animals and heard reports the farmers were using the salt to season their own food. People insisted this 'real' salt made available for everyday use and the brand was born"
Raymond, my most recent purchased bag of Redmond REAL SALT has an expiration date of 07.04.2029. SALT is a preservative so you good to go! The only thing this particular salt will do is clump if high humidity exists. You'll go to use the salt shaker and nothing will come out because it has clumped together--NO PROBLEM. Just tap the salt shaker a couple of times on the table so it breaks loose and then use it freely. The clumping does not affect taste or shelf life. ENJOY!
This one can be poured straight into into the salt shaker. They also have coarse salt that probably does need to be ground: http://smile.amazon.com/One-16-Ounce-Real-Salt-Coarse/dp/B001CM8RZU/ref=sr_1_1?ie=UTF8&qid=1401558680&sr=8-1&keywords=real+salt+coarse
