Vitamin, b-1, or thiamin, helps your body convert food into energy. Your brain depends on vitamin, b-1 to metabolize glucose, and your nerves need it to function properly. Vitamin B 12, also called cobalamin, is a water-soluble vitamin that has a key role in the normal functioning of the nervous system via the synthesis of myelin.

and depression and may help relieve pain from fibromyalgia. The recommended daily intake for vitamin B-12.4 micrograms for men and women. Good sources include enriched cereals and animal-based foods, such as fish, chicken, beef, milk, cheese and yogurt. Vitamins B-1 and B-12 aren't known to cause side effects, whether you get them through your diet or take supplements. Vitamin B-6 from foods wont cause problems, but taking a large dose of supplemental B-6 can cause pain and numbness in your arms and legs. To prevent overconsumption, you shouldn't consume more than 100 milligrams of vitamin B-6 daily. Slow-release potassium supplements and medications used to treat gastroesophageal reflux disease may interfere with your bodys ability to absorb vitamin B-12. Extra calcium may improve its absorption, but talk to your healthcare provider about your vitamin needs if you take medications.

What Are the benefits of Vitamins


Some of the best sources are enriched ready-to-eat cereals made from whole grains, but the amount youll get varies from one brand to the next. Other rich sources are roasted ham, pork chops, brown rice, lentils, peas and internet beans such as navy, black, pinto, lima and kidney beans. Vitamin B-6, vitamin B-6 actives enzymes responsible for producing energy, neurotransmitters, red blood cells and white blood cells that support the immune system. You may help keep your heart healthy by getting an adequate amount of vitamin B-6 because it removes the amino acid homocysteine from your blood. High levels of homocysteine are associated with an increased risk of developing cardiovascular disease. Your daily diet should include.3 milligrams of vitamin B-6. Tuna, salmon, poultry, beef, potatoes, spinach, bananas and fortified breakfast cereals are all good sources. Vitamin B-12, your body needs vitamin B-12 to make neurotransmitters, hemoglobin and dna.

Receptors on the surface of the ileum (final part of the small intestine) take up the if-b12 complex only in the presence of calcium, which is supplied by the pancreas (5). Vitamin B12 can also be absorbed by passive diffusion, but this process is very inefficient—only about 1 absorption of the vitamin B12 dose is absorbed passively (2). The prevalent causes of vitamin B12 deficiency are (1) an autoimmune condition known as pernicious anemia, and (2) a disorder called food-bound vitamin B12 malabsorption. Both conditions have been associated with a chronic inflammatory disease of the stomach known as atrophic gastritis. Atrophic gastritis Atrophic gastritis is thought to affect 10-30 of people over 60 years of age (6). The condition is frequently associated with the presence of autoantibodies directed toward stomach cells (see pernicious anemia ) and/or infection by the bacteria, helicobacter pylori (. Pylori infection induces chronic inflammation of the stomach, which may progress to peptic ulcer disease, atrophic gastritis, and/or gastric cancer in some individuals.

This biotin enzyme is required for the synthesis of the amino acid, methionine, from homocysteine. Methionine in turn is required for the synthesis of s-adenosylmethionine, a methyl group donor used in many biological methylation reactions, including the methylation of a number of sites within dna, rna, and proteins (3). Aberrant methylation of dna and proteins, which causes alterations in chromatin structure and gene expression, are a common feature of cancer cells. Inadequate function of methionine synthase can lead to an accumulation of homocysteine, which has been associated with increased risk of cardiovascular disease ( Figure 1 ). Cofactor for L-methylmalonyl-coenzyme a mutase 5-deoxyadenosylcobalamin is required by the enzyme that catalyzes the conversion of L-methylmalonyl-coenzyme a to succinyl-coenzyme a (succinyl-coa which then enters the citric acid cycle ( Figure 2 ). Succinyl-coa plays an important role in the production of energy from lipids and proteins and is also required for the synthesis of hemoglobin, the oxygen-carrying pigment in red blood cells (3).

Deficiency In healthy adults, vitamin B12 deficiency is uncommon, mainly because total body stores can exceed 2,500 μg, daily turnover is slow, and dietary intake of only.4 μg/day is sufficient to maintain adequate vitamin B12 status (see rda ) (4). In elderly individuals, vitamin B12 deficiency is more common mainly because of impaired intestinal absorption that can result in marginal to severe vitamin B12 deficiency in this population. Causes of vitamin B12 deficiency Intestinal malabsorption, rather than inadequate dietary intake, can explain most cases of vitamin B12 deficiency (5). Absorption of vitamin B12 from food requires normal function of the stomach, pancreas, and small intestine. Stomach acid and enzymes free vitamin B12 from food, allowing it to bind to r-protein (also known as transcobalamin-1 or haptocorrin found in saliva and gastric fluids. In the alkaline environment of the small intestine, r-proteins are degraded by pancreatic enzymes, freeing vitamin B12 to bind to intrinsic factor (if a protein secreted by specialized cells in the stomach.

Vitamin B1 - thiamin - the world's

Older individuals and vegans are advised to use vitamin B12 fortified foods and supplements to meet their needs. (More information) The long-term use of certain medications, such as inhibitors of stomach acid secretion, can adversely affect vitamin B12 absorption. (More information) Vitamin B12 has the cosi largest and most complex chemical structure of all the vitamins. It is unique among vitamins in that it contains a metal ion, cobalt. For this prijs reason cobalamin is the term used to refer to compounds having vitamin B12 activity. Methylcobalamin and 5-deoxyadenosylcobalamin are the forms of vitamin B12 used in the human body (1). The form of cobalamin used in most nutritional supplements and fortified foods, cyanocobalamin, is readily converted to 5-deoxyadenosylcobalamin and methylcobalamin in the body. In mammals, cobalamin is a cofactor for only two enzymes, methionine synthase and L-methylmalonyl-coenzyme a mutase (2). Function Cofactor for methionine synthase methylcobalamin is required for the function of the folate-dependent enzyme, methionine synthase.

(More information the preservation of, dna integrity is dependent on folate and vitamin B12 availability. Poor vitamin B12 status has been linked to increased risk of breast cancer in some, but not all, observational studies. There is a need to evaluate whether supplemental vitamin B12, along with folic acid, could help reduce breast cancer incidence. (More information low maternal vitamin B12 status has been associated with an increased risk of neural tube defects (ntd but it is not known whether vitamin B12 supplementation could help reduce the risk of ntd. (More information vitamin B12 is essential for the preservation of the myelin sheath around neurons and for the synthesis of neurotransmitters. While hyperhomocysteinemia cooper may increase the risk of cognitive impairment, it is not clear whether vitamin B12 deficiency contributes to the risk of dementia in the elderly. Although b-vitamin supplementation lowers homocysteine levels in older subjects, the long-term benefit is not yet known. (More information) Both depression and osteoporosis have been linked to diminished vitamin B12 status and high homocysteine levels. (More information) Products of animal origin constitute the primary source of vitamin B12.

Contents, español, summary, vitamin B12 or cobalamin plays essential roles in folate metabolism and in the synthesis of the citric acid cycle intermediate, succinyl-coa. (More information vitamin B12 deficiency is commonly associated with chronic stomach inflammation, which may contribute to an autoimmune vitamin B12 malabsorption syndrome called pernicious anemia and to a food-bound vitamin B12 malabsorption syndrome. Impairment of vitamin B12 absorption can cause megaloblastic anemia and neurologic disorders in deficient subjects. (More information normal function of the digestive system required for food-bound vitamin B12 absorption is commonly impaired in individuals over luizenkam 60 years of age, placing them at risk for vitamin B12 deficiency. (More information vitamin B12 and folate are important for homocysteine metabolism. Elevated homocysteine levels in blood are a risk factor for cardiovascular disease (CVD). Although b vitamin supplementation has been proven effective to control homocysteine levels, current data from intervention trials have not shown that lowering homocysteine levels decreases cvd risk.
