Thorne Ferrasorb® Iron Bisglycinate Capsules - High Absorption, Gentle Formula

Superior Absorption & Bioavailability: Ferrasorb® utilizes iron bisglycinate chelate, where iron is bound to two glycine molecules, protecting it from interactions with other dietary components that typically inhibit iron absorption. This chelated structure allows the iron to remain intact through the digestive tract and be absorbed via amino acid transport pathways rather than competing for standard iron receptors, resulting in significantly higher bioavailability compared to ferrous sulfate or ferrous fumarate while dramatically reducing common side effects like nausea and constipation.

Energy Production & Reduced Fatigue: Iron serves as an essential cofactor for cytochrome enzymes within mitochondria, the cellular powerhouses responsible for ATP energy production. Adequate iron levels enable efficient oxygen delivery to tissues and optimal mitochondrial function, directly addressing the profound fatigue, weakness, and reduced exercise tolerance associated with iron deficiency. By restoring healthy iron stores, Ferrasorb® supports sustained physical and mental energy throughout the day, enhanced endurance during activity, and faster recovery from exertion.

Healthy Red Blood Cell Formation: As a critical component of hemoglobin synthesis, iron enables the bone marrow to produce healthy red blood cells capable of binding and transporting oxygen from the lungs to every cell in the body. Ferrasorb® provides the elemental iron necessary to support erythropoiesis (red blood cell production), maintain healthy hemoglobin and hematocrit levels, and prevent iron deficiency anemia. This is particularly important for menstruating women, pregnant individuals, growing adolescents, and anyone with increased iron requirements or documented deficiency.

Gentle, Well-Tolerated Formula: Enhanced with folate (400mcg as L-5-methyltetrahydrofolate from Quatrefolic®) and vitamin B12 (150mcg as methylcobalamin), Ferrasorb® provides complementary nutrients essential for red blood cell maturation and DNA synthesis. The addition of vitamin C from ascorbyl palmitate further enhances iron absorption while providing antioxidant protection. This comprehensive formulation eliminates the need for multiple supplements and ensures all critical co-factors for healthy iron metabolism are present in their most bioavailable forms.
