Iron from food sources in heme and non-heme forms with varying absorption rates.
Iron obtained from food sources, existing in two forms: heme iron (from animal products) and non-heme iron (from plant sources). Heme iron has better bioavailability than non-heme iron.
Dietary iron is essential for oxygen transport in the blood and energy production in cells. The body absorbs heme iron (found in red meat, poultry, and fish) more efficiently at 15-35% absorption rate, compared to non-heme iron (found in legumes, grains, and vegetables) which is absorbed at only 2-20%. This difference is crucial for individuals at risk of iron deficiency, as they may need to consume significantly more plant-based iron or combine it with enhancers like vitamin C to meet their needs.
Essential mineral for hemoglobin synthesis, oxygen transport, and cellular energy metabolism.
Consume a variety of iron sources daily, combining heme sources with vitamin C-rich foods to enhance non-heme iron absorption. For vegetarians and vegans, prioritize legumes, fortified grains, and seeds while pairing them with citrus fruits or tomatoes.
Dietary iron quality and absorption vary significantly between animal and plant sources, requiring strategic food combinations for optimal nutrition.
