SUGGESTED USE: For short-term use only (up to 2 weeks). Adult/Adultescent: 130 mg (2 tablets). Children: 65 mg (1 tablet).

300 REAL TABLETS: These are actually tablets that are easily divisible if needed for smaller children and infants. Capsules can't be divided easily and have a shorter shelf life than tablets. Use is the same as potassium iodate tablets, ki pills 130mg or other iodine supplements.
