One of the best ways to obtain balanced minerals is to use ionic minerals versus colloidal or metalic minerals (as found with most supplements). They are an angstrom in size which is the size required for cellular absorption. Most other minerals are a micron in size, which is thousands of times larger and, therefore, difficult to absorb.

Their best product is VIBE with balanced amounts of all essential ionic minerals including calcium and copper. Also, once the liver is all clean, calcium absorption will improve. You need bile to absorb calcium and other minerals.
