ConcenTrace® isn’t actually something TMR makes. It’s an amazing complex of full spectrum ionic trace minerals that has been made by Mother Nature. For thousands of years, every sprouting seed and towering tree has helped dissolve minerals, raising them from deep within the soil to the surface, where they are easily washed away. But they don’t just wash away. They are carried in the rivers and streams into oceans and seas like the Great Salt Lake (GSL) in Utah, USA. But the GSL is unique because it has no outlets and is considered an inland sea. Therefore, the GSL is rich in minerals that have been deposited there over these thousands of years.
