Chelation is the suspension of a mineral between two or more amino acids. A chelated mineral is a mineral such as chromium, copper, zinc, manganese, cobalt or iron (there are others) that is bonded to "small proteins", peptides or amino acids.

Chelated minerals are organic trace minerals designed to enhance mineral absorption and improve bioavailability. Common inorganic forms of trace minerals may interact with other feed ingredients such as lipids, proteins, fiber or other minerals, inhibiting absorption. When minerals are bound to chelating agents such as amino acids and hydrolyzed proteins they become more stable and are much less reactive in the digestive tract. In fact, chelation is a naturally occurring process in the living body for transporting minerals across the intestinal wall during digestion.

Samjo Life Science has been producing a wide variety of chelated minerals especially chromium picolinate with cutting-edge technology and has been making progress every year.
