America's #1 selling trace mineral supplement Concen Trace Trace Mineral Drops is an all natural mineral concentrate that's made by using ConcenFlo, the proprietary harvesting process. ConcenTrace contains over 72 naturally occurring ionic trace minerals from the Great Salt Lake with 99% sodium removed. Ideally, minerals should come from eating a raw food diet. However, even eating a raw food diet isn't enough since researchers have proven that soils have been depleted of minerals. Therefore, if it's not in the soil, it's not in the food. Here's where ConcenTrace comes in - taking ConcenTrace everyday ensures you're getting a full spectrum of ionic trace minerals, which are the same kind of bioavailable ionic trace minerals that are found in foods.
