My opinion from the description:
It looks to me like they’ve gone off the rails. Their original concept was reasonable but tedious: test many ions and replace individually. Not every element they suggested was sensible, but folks got good results from the others.
Now they seems to be going wild on the addition idea veering into elements with little or no known biological role;
Liquid-Mud provides the beneficial supplementation of natural occurring essential minerals and trace elements also known as Rare Earth Elements (REE),
With the Liqui-Mud, these minerals and trace elements that are very difficult to dose, and are naturally based such as Beryllium, Gold, Gallium and many other minor trace elements, are simply supplemented on a daily basis with this Product.
I cannot see any reason to dose these.
The product may have benefits, but not for the reasons given.
