38 results about "Iron supplement" patented technology

Iron supplements, also known as iron salts and iron pills, are a number of iron formulations used to treat and prevent iron deficiency including iron deficiency anemia. For prevention they are only recommended in those with poor absorption, heavy menstrual periods, pregnancy, hemodialysis, or a diet low in iron. Prevention may also be used in low birth weight babies. They are taken by mouth, injection into a vein, or injection into a muscle. While benefits may be seen in days up to two months may be required until iron levels return to normal.

Methods for determining the amount of encapsulated and free iron in a sample

PCT designated stageWO2026176335A1ReceptorIron supplement
Methods of increasing systemic iron availability in a human subject using plant-derived ferritin-bound iron are provided. In certain embodiments, ferritin-bound iron is orally administered in an amount effective to produce sustained systemic iron exposure characterized by measurable serum iron levels at least 24 hours after administration. In some embodiments, administration produces a delayed peak serum iron concentration and provides controlled systemic iron delivery relative to conventional iron supplements. In certain embodiments, administration of ferritin-bound iron results in a reduced hepcidin response relative to ferrous sulfate, thereby facilitating improved iron utilization. The ferritin-bound iron may be absorbed through receptor-mediated uptake mechanisms that provide controlled intracellular iron release and sustained systemic availability. The methods are useful for increasing systemic iron availability and for treating or preventing iron deficiency and iron deficiency anemia in human subjects.
