A higher bioavailability of the dietary iron can be achieved by increasing the content of food components enhancing iron absorption ascorbic acid meatfish or by decreasing the content of inhibitors eg phytates tannins.

In the intestinal tract vitamin C enhances iron bioavailabil-ity by maintaining non-heme iron in the ferrous state. Vitamin C also promotes duodenal ferric reductase activity further con-tributing to the absorption potential of dietary iron17 Hallberg et al18 showed that iron absorption increased in a.

Vitamins Personal Care and More. 01102014 Vitamin C regulates iron metabolism by increasing Tf-dependent and non-Tf iron uptake the latter of which occurs by a novel transplasma membrane ascorbate-cycling mechanism stimulating ferritin synthesis inhibiting lysosomal ferritin degradation via autophagy and decreasing cellular iron efflux.

Iron deficiency is a major world health problem that is to a great extent caused by poor iron absorption from the diet. Vitamin C can create a more acidic environment in the stomach and prevent the oxidization of ferrous iron to ferric iron. AA is known to enhance the availability and absorption of iron from non-heme iron sources.

The reduction of iron by AA has been suggested to increase dietary absorption of. Several dietary factors can influence this absorption. Heme iron derived from hemoglobin and myoglobin is well absorbed and relatively little affected by other foods eaten in the same meal.
