Chelation occurs when an amino acid “grabs” and holds onto a mineral molecule, (magnesium glycinate for example glycine is the amino acid) usually making a ring formation that doesn’t break down in the digestive process.This is why chelated minerals are more bioavailable - by “surviving digestion” the minerals can get carried to your cells bound to the amino acid. Any mineral (magnesium, zinc, etc) should always be taken in a chelated form for increased absorption and bioavailability rates. These superior chelated minerals are rare, expensive, and take a long time to produce. In fact, there are only few mineral suppliers in the world that actually make 100% reacted magnesium chelates. Most magnesium supplements on the market that claim to contain chelated magnesium actually do not and are mis-labeled. The problem starts with the ingredient suppliers. Many suppliers claim to make chelated magnesium (like magnesium glycinate) because it's a superior form and it allows them to charge a higher price. However the magnesium they sell is actually only partially chelated and is blended with an unknown percentage of unbound inorganic magnesium (like magnesium oxide). The result is an unbound inorganic magnesium that is very poorly absorbed, thus causing the bowel intolerance symptoms caused by most magnesium supplements. Albion Laboratories has been selling magnesium glycinate chelate to supplement companies that is NOT fully chelated, containing undisclosed amounts of magnesium oxide. Affected supplement brands include Bluebonnet Nutrition, Vitacost, and Nature’s Lab. So far there have been two class-action suits brought against them.
