Minerals: major minerals, calcium, phosphorus, potassium, sulfur, sodium, chloride, magnesium. Trace minerals: trace minerals, iron, zinc, copper, manganese, iodine, selenium. Iron: cofactor to many enzymes involved in making amino acids, collagen, hormones, and neurotransmitters, most of the body"s iron is found in two proteins, hemoglobin, myoglobin, iron helps accept, carry, and then release oxygen. in the red blood cells in the muscle cells, food sources, heme iron (~25% absorbed): Tannic acid and other polyphenols in tea and coffee: recommendations, rda for men: 8 mg/day, rda for women of child bearing age: 18 mg/day, rda for women over 50: 8 mg/day, ul: 45 mg/day, deficiency, most common nutrient deficiency worldwide. Iron deficiency anemia = severe depletion of iron stores results in low hemoglobin production: pale and small red blood cells, can"t carry enough oxygen from the lungs to the tissues, fatigue, weakness, headaches, behavior, pica.
