The trace element is an essential component of numerous oxygen– and electron-transferring active groups. Iron deficiency leads to a decrease in the activity of the iron-dependent enzymes involved, especially oxidoreductases and monooxigenases. Oxygen transport and storage As an essential building block of hemoglobin, the main role of iron is to transport oxygen from the lungs … Iron: Features
Interactions of iron with other micronutrients (vital substances): Vitamin C To promote absorption of iron by reduction to Fe2+, 25 mg to 75 mg or more of vitamin C must be present in a meal. It is also possible that vitamin C increases the stability of intracellular ferritin. As a result, phagocytosis of ferritin into … Iron: Interactions
The most common symptoms of iron deficiency are the anemia deficiency symptoms Fatigue Rapid heartbeat – tachycardia Shortness of breath under stress Iron deficiency worsens athletic performance and physical work capacity in several ways: Low hemoglobin in red blood cells iron deficiency anemia – results in decreased oxygen delivery to muscles. In the muscle cells … Iron: Symptoms of Deficiency
At-risk groups for iron deficiency include individuals with. Inadequate intake (in the case of malnutrition or a one-sided, low-iron diet – for example, vegans). Poor absorption (small intestinal villous atrophy, for example, in sprue). Deficient utilization (in condition after gastric resection). Increased demand – growth in young people and losses due to menstruation of about … Iron: Risk Groups
The United Kingdom Expert Group on Vitamins and Minerals (EVM) last evaluated vitamins and minerals for safety in 2003 and set a so-called Safe Upper Level (SUL) or Guidance Level for each micronutrient, provided sufficient data were available. This SUL or Guidance Level reflects the safe maximum amount of a micronutrient that will not cause … Iron: Safety Assessment
In the National Nutrition Survey II (NVS II, 2008), the dietary behavior of the population was investigated for Germany and it was shown how this affects the average daily nutrient intake with macro- and micronutrients (vital substances). The intake recommendations (D-A-CH reference values) of the German Nutrition Society (DGE) are used as the basis for … Iron: Supply Situation
The intake recommendations (D-A-CH reference values) of the German Nutrition Society (DGE) presented below are aimed at healthy people of normal weight. They do not refer to the supply of sick and convalescent people. Individual requirements may therefore be higher than the DGE intake recommendations (e.g., due to dietary habits, consumption of stimulants, long-term medication, … Iron: Supply
