摘要
Iron deficiency anemia affects approximately 1.62 billion people worldwide,yet traditional iron supplements present bioavailability limitations and gastrointestinal side effects.This randomized,double-blind clinical trial investigated a novel Auricularia auricula polysaccharide-iron complex(AAPIC)compared with heme iron and ferrous glycinate in 180 iron-deficient adults receiving 30 mg elemental iron daily for 12 weeks.AAPIC achieved comparable hemoglobin improvements(from 98.3±8.7 to 126.5±9.2 g/L)to heme iron(from 97.8±9.1 to 128.3±8.6 g/L)and was significantly superior to ferrous glycinate(from 98.6±8.9 to 119.7±10.3 g/L;p<0.001).Iron absorption efficiency showed AAPIC at 23.7±4.2%,heme iron at 25.1±3.8%,and ferrous glycinate at 18.4±5.1%.Toxicological assessments revealed no hepatotoxicity,nephrotoxicity,or mutagenicity.Gastrointestinal adverse events occurred in 8.3%of AAPIC recipients versus 15.0%with ferrous glycinate and 10.0%with heme iron.The polysaccharide component facilitates iron transport through enhanced intestinal uptake mechanisms.AAPIC represents a promising,well-tolerated alternative with clinical efficacy comparable to established iron formulations.
