What are Chelated Minerals?
The word chelate comes from the Greek word "chele", which means claw. Chelated minerals refer to a molecular reaction or binding process that occurs between a nutritional mineral and the protein source (the ligand). This binding process forms a ring structure, sharing electrons between the mineral and the ligand, making the mineral compound more stable for greater nutritional utilization and absorption in the body. Examples of naturally occurring chelates are iron in hemoglobin and magnesium in chlorophyll.
Why Should I Take Chelated Minerals?
Advantages of Chelated Mineral Supplements
(1) Better NutritionMinerals are catalysts for every enzyme in the human body. Our bodies need several different minerals for essential human nutrition. Deficiencies and imbalances can lead to serious health conditions. Ideally, we should absorb most minerals through our food. However, the modern diet is deficient in mineral nutrition. Food that is highly processed and exposed to contaminants limits nutritional quality. Additional minerals are needed to restore optimal levels of minerals in the body.
(2) Greater BioavailabilityDietary minerals are often obtained from inorganic sources or mineral salts. Unfortunately, inorganic sources are poorly assimilated and/or ionize easily, yielding low bioavailability. ie. Baker- found manganese sulfate (32.5% elemental Mn) in corn/soy diet had 1-6% bioavailability, providing only 2% of the manganese to be utilized. Minerals found in food are bound to proteins. In a similar fashion, amino acids are protected bythe ring structure in a mineral chelate. This protects the mineral as it passes through the acidity of the digestive system to make the mineral more bioavailable.
University of Florida studies indicate that chelated minerals have more bioavailability and absorption than inorganic minerals. Our product’s bioavailability was statistically more significant than seven competitors.
(3) Increased StabilityChelated minerals, because of their protective ring structure, have the ability to avoid inhibition such as oxidation-reduction reactions when mixed with fat soluble vitamins. The ring structure also enables the mineral to avoid antagonism with other minerals.
(4) ResearchOur research is based on published university and industry studies that have analyzed the bioavailability of our original patented chelates (AAFCO definition for chelates in agriculture, Metal Proteinates).

How is Biokey® different from other chelated mineral supplements?
The Biokey® line of amino acid chelates is a premium line of chelated products. Chelated minerals' quality is determined by the degree and integrity of the bond between a nutritional mineral and molecule. Our Biokey® product line has one elemental value per mineral that is consistent with a mineral to ligand ratio for optimum chelation. Biokey® Amino Acid Chelates provides a multiple amino acid chelate specifically formulated for each mineral's properties, supplying maximum binding and bioavailability of the mineral. University data supports the use of multiple ligand chelates by showing greater bioavailability in various studies.
