2 Pack of 140 Real Potassium Iodide Tablets per bottle (enough for 2 weeks for 5-10 people), unlike other brands that only offer a 60 count bottle. Most other brands offer capsules instead of the recommended tablets or liquid tincture. Potasium iodide is a stable iodine salt. A single dose of potassium iodide lasts for 24 hours. Regular table salt or food contain very small amounts of Potassium Iodide. Dietary supplements that contain pure iodine in the place of an potassium iodide tablet also only contain micro amounts. This product is great to have in any type of kit and can simply give peace of mind for the entire family. A great extension to any prepper's kit.
