compromised the effects of taking 50 mg beta-carotene every other day to a placebo in over 22,000 male physicians and found no adverse health effects [ ]. Also, a trial that tested the ability of four different nutrient combinations to help prevent the development of gastric cancers in 30,000 men and women in China suggested that after five years those participants who took a combination of the beta carotins, and vitamin e had % reduction in cancer deaths [ ]. In one lung cancer trial, men who consumed more than 11 grams/day of alcohol (approximately one drink per day) were more likely to show an adverse response to beta-carotene supplements [ ], which may suggest a potential relationship between alcohol and beta-carotene. The carotene or other carotenoids. Instead, it concluded that beta-carotene supplements are not advisable for the general population. As stated earlier, however, they may be appropriate 13 as pro vitamin a source for the prevention of vitamin a deficit in the specific populations [ vitamin a inlets and in the healthy parliamentary allowance

deficit . The inability to synthesize DNA during erythrocyte maturation leads to abnormally large erythrocytes termed macrocytic anemia. Folate deficiencies are rare due to the adequate presence of folate in food. Poor dietary habits as those of chronic alcoholics can lead to folate deficiency. The predominant causes of folate deficiency in non-alcoholics are impaired absorption or metabolism or an increased demand for vitamin . The predominant condition requiring an increase in the daily intake of folate is pregnancy. This is due to an increased number of rapidly proliferating cells present in the blood. The need for folate will nearly double by the third trimester of pregnancy. Certain drugs such as anticonvulsants and oral contraceptives can impair the absorption of folate. Anticonvulsants also increase the rate of folate metabolism. back to the top
folat (folacin or folic acid): Functions: Folate is , which operate a water-soluble vitamin , which play a substantial cylinder in producing DNA and RNA to make new body cells. It also , with vitamin b12, in order hemoglobin in red blood cells. Deficiency problems: Impaired cell division and growth, a type of anemia, and, during the first trimester of pregnancy, increased risk of delivering a baby with neural tube defects including spina bifida. Food sources: Leafy vegetables, orange juice and some fruits, legumes, liver, yeast breads, wheat germ and some fortified cereals. Excess amounts: May interfere with medications and cause convulsions in people with epilepsy. It can to form also vitamin b12 the deficits, are leading to the permanent nerve damage if not , covers which with vitamin b12 . Back is treated, in order vitamin b12 (cobalamin): Functions: vitamin b12 to exceed, a water-soluble vitamin , operating with folat to make red blood cells. It also serves in body cells as a vital part of many body chemicals and helps the body use fatty acids and some amino acids. Deficiency problems: Anemia, fatigue, nerve damage, a smooth tongue, very sensitive skin. B12 deficiencies may be hidden when extra folate is taken to treat or prevent anemia.

Stem cells are dependent on retinoids for normal into red blood cells. additionally, vitamin a seems, mobilization of iron from storage sites to the developing red blood cell for incorporation into , the oxygen carrier in red blood cells (2, 7). Nutrient interactions deficiency is thought to to enable obstructs vitamin a metabolism in some methods : (1) zinc deficiency results in decreased synthesis of retinol binding protein (RBP), which transports retinol through the circulation to tissues (e.g., the retina) and also protects the organisma against potential toxicity of retinol; (2) zinc deficiency results in decreased activity of the enzyme that releases retinol from its storage form, retinyl palmitate, in the liver; and (3) zinc is required for the enzyme that converts retinol into retinal . At present, the health consequences of zinc the deficit on vitamin a supporting status in humans, unclear vitamin a deficit can . vitamin a supplement verbittern has favourable of effects on iron deficiency anemia and improves iron nutritional status among children and pregnant women. The combination additional vitamin a is and iron seems reduce anemia more effectively than either supplemental iron, or vitamin a is allein . Moreover, studies in rats have shown that iron deficiency alters plasma and liver levels vitamin a vitamin a of the deficit and sight vitamin a of the deficit among children in developing nations is the leading preventable cause of blindness .

The onset of infection reduces blood retinol levels very rapidly. This phenomenon is generally believed to be related to decreased of retinol binding protein (RBP) by the liver. In this manner, infection stimulates a vicious cycle , because insufficient vitamin a is being located in connection supporting status, stated to increased severity and likelihood of death from infectious disease . However, a recent review of four studies that vitamin a supplement is not favourable in reducing the mother-to-child transmission of HIV .

The latest RDA is based on the amount needed to ensure adequate stores (four months) of vitamin a in the body support normal reproductive function, immune function, gene expression , and vision . The table below lists the RDA values in both micrograms (mcg) of Retinol Activity Equivalents (RAE) and international units (IU). For more information on these units, see the section on Recommended Dietary Allowance (RDA) for vitamin a as preformed vitamin a (Retinol Activity Equivalents) Life Stage Males: mcg/day (IU/day) Females: mcg/day (IU/day) children was improved
not assigned radicals and reacting oxygen species that can be generated during normal metabolism as well as through exposure to toxins and pollutants (e.g. smoking). vitamin c are also to regenerate other antioxidants like vitamin e, which was heavier vitamin c deficit well-known for many centuries as the potentially fatal disease, . By the late 1700's the British navy was aware that scurvy could be cured by eating oranges or lemons , even if vitamin c separate until the early 1930's. Symptoms of scurvy include bleeding and bruising easily, hair and tooth loss, joint pain and swelling. Such symptoms appear to be related to the weakening of blood vessels, connective tissue, and bone, which contain collagen. Early symptoms of scurvy such as fatigue result from diminished levels of , needed to derive energy from fat, or decreased synthesis of the norepinephrine (see ). Scurvy is rare in developed countries because it can be prevented by not as few vitamin c however would be daily in the layer, new cases have occurred in children and the elderly on very restricted diets The Recommended Dietary Allowance (RDA) In the U.S., the recommended dietary allowance ( ) for vitamin c recently corrected upward from 60 mg daily for men and women. The RDA continues to be based primarily on the prevention of deficiency disease, rather than the prevention of chronic disease and the promotion of optimum health. The recommended intake for smokers is 35 mg/day higher than for nonsmokers, because smokers are under increased oxidative stress from the toxins in cigarette smoke and generally have lower blood levels vitamin c recommended diã¤tetischen permit (RDA) for vitamin c of life step men were (mg/day)
