Angstrom is a unit of measurement, that as I've read is discouraged from use. So from what I read, they suggest a particle size of 0.1 nanometers.

What Is Angstrom?
Angstrom is the smallest wavelength of light and used to describe the length of molecules of minerals. Angstrom is a measurement to illustrate how small the particles are in the mono-atomic form. Mono=One and Atomic=atom, therefore meaning one atom form. Colloids (like Colloidal Silver ) and complex minerals are all in particle size of approximately a micron. One human hair is about 50 microns wide. An angstrom is 10,000 times smaller than a micron.

The nature of minerals in their most elemental( basic) state is that of atoms. Only in this state can they carry an electrical charge, positive or negative. ( Ionic just a big advertising word to confuse you!) The body can only take up these elements if they carry an electrical charge. (see a periodic table for charges) When minerals do not have an electrical charge they are locked-up and unusable. Minerals in complex and colloidal forms are not cell ready. They must be broken down further by digestion and even then are at times not able to be carried through the cell as the cell is much to small to allow the micron to enter. No matter how much you want to, you will never be able to crawl in side of a pop bottle. it is the same principle, some thing too large cannot enter something smaller than it's self. It doesn't matter that amino acids are added to the large particles or that they have been ionized (charged), the cell is still too small to accept it.

Some complex minerals and colloid supplements are more than likely causing more harm than good. Complex minerals are those like Calcium Carbonate, one calcium atom and three carbon atoms. CaCO3. That’s is three times the carbon for every calcium. They are bound tightly together and almost useless for the body. ( Something is better than nothing.) Molecular bonds the body recognizes and can break apart are the loose bonds found in plants, that is, providing that the body is working to break these loose bonds have a functional digestive tract. Most Americans do not. ( Americans eat a lot of junk and need a digestive enzyme)

Colloidal Minerals must pass throught the digestive tract first. Angstrom Minerals are so small that they are absorbed into the cells as soon as you put them in your mouth. Quicker absorbtion, Faster, Stronger results= MORE MINERAL FOR YOUR DOLLAR!
