• Answer:

  Fat-soluble vitamins A,D,E,K Vitamin A deficiency can lead to night blindness Vitamin D deficiency can lead to rickets (failure of bons to calcify) or osteomalacia (abnormal bone synthesis) Vitamin E (alpha-tocopherol) deficiency produces a normocytic normochromic anemia Vitamin K deficiency is essential to the formation of coagulation factors (prothrobin)…no vit K = no clots = you bleed constantly Water-soluble vitamins C and B complex Vitamin C (ascorbic acid) considered important in reducing the risk of certain cancers and the common cold B complex vitamins most serve as enzyme cofactors. Deficiency in any B vitamin affects the body’s metabolism. (thiamine, riboflavin, niacin, pantothenic acid, biotin, pyridoxine (B6), the folates and cyanocobalamin (B12) B12 deficiency produces pernicious anemia Folate deficiency leads to megaloblastic anemia and in pregnant women possible fetal neural tube defects. Sodium Most abundant xtracellular cation regulated by the renal system. Disorders hypo/hyper-natremia Potassium Major intracellular cation regulates activity at neuromuscular junction and cardiac muscle contraction and pH Disorders hypo/hyper-kalemia, hypokalmia can produce irregular heartbeat. Iron disease states are Iron deficiency anemia, Iron overload (Hemosiderosis, Hemochromatosis-Hereditary, Sideroblastic anemia, Acquired). Mg deficiency are mitral valve prolapse, migraines, attention deficit disorder, fibromyalgia, asthma and allergies. http://www.ctds.info/5_13_magnesium.html Zinc http://www.ctds.info/zinc1.html really detailed site
