Iron is an important component of hemoglobin, a protein in red blood cells that delivers oxygen to tissues throughout the body. It is also a part of myoglobin, a protein that helps muscle cells store oxygen, and ferritin, the body's main iron storage protein found in the intestines, liver and spleen. Iron bound to ferritin is readily mobilized to meet the body's demands. Ferrochel brand iron bis-glycinate was developed using unique patented chemistry, allowing it to be absorbed rapidly from the lumen of the intestines into mucosal cells and then released for transport throughout the body. The intestinal mucosal tissue tightly controls the release of Ferrochel, supporting the safety profile of this iron amino acid chelate. In a double blind, randomized, placebo-controlled trial, iron supplementation supported healthy ferritin levels and enhanced energy and well-being in female subjects. Another report emphasizes the importance of maintaining healthy serum ferritin for optimal performance in elite female athletes. In another randomized trial, iron supplementation or a high iron diet supported cognitive wellness and moderated fatigue in women of childbearing age. Ester-C is a natural, non-acidic water-soluble form of vitamin C that is distinguished by its unique chemical composition and biological activity. It is manufactured in an exclusive, water-based process that results in a mixture of naturally occurring vitamin C metabolites, including ascorbate, dehydroascorbate, and threonate. Vitamin C aids in the absorption of iron and the formation of red blood cells. Research indicates that vitamin C supports healthy hemoglobin levels.*
