This product does what it says. I use it for iodine supplementation of my health. Since starting the iodine I have noticed I sleep better, feel stronger, and have an endurance outlasting my co-workers. I use this twice a day 10 drops each. Once in the morning when I wake up, and once in the evening when I get home from work for recovery. Use this supplement in conjunction with an animal based diet and my health has gone from terminal to strong, active, and non-terminal.
